Sugar-sweetened carbonated beverage consumption correlates with BMI, waist circumference, and poor dietary choices in school children

A randomized controlled trial of sweet basil leaf powder-enriched cookies for anemia management in adolescent girls

The study aimed to evaluate the effectiveness of sweet basil leaf powder as a natural source of iron for the treatment of anemia in adolescent girls. Purposive sampling technique of two-stage sampling; part of the nonprobability sampling approach. Out of 2400 approached adolescent girls, 1645 agreed to participate and their nutritional status was assessed. Of these, 89.95% had clinical signs and symptoms of anemia, and 59.79% were found to be anemic based on Hb levels. From the anemic group, 65.18% were randomly selected to receive either B0 (Control), B1 (12.699 g FeSO4.7H2O/100 g), and B3 (16 g SBLP/100 g) cookies for 4 months. At the end of the intervention, the assessment of nutritional status, complete blood count, serum iron, serum ferritin, serum total iron-binding capacity (TIBC), and transferrin saturation was explored. Hematological parameters such as Hb, Hct, TIBC, MCV, MCH, MCHC, serum iron, and serum ferritin were significant (p ≤ .05). The result showed that the serum Fe was highest in group B3 while a significant decline was noted for group B0. Serum ferritin for B1 was better than B3. The entire treatment for transferrin saturation showed a highly significant increasing trend in B3 and B1, regardless of the control. TIBC levels raised in the control group while in all other treatments, it declined. The study demonstrated that SBLP-fortified cookies can be an effective treatment option for anemia, as evidenced by significant improvements in key hematological parameters.

Sleep Duration Is Associated with Household Food Insecurity and Sugar-Sweetened Beverage Intake Among Women, Infants and Children Participating Children Ages 0-5

PURPOSE

To determine associations between child and household characteristics and sleep duration among low-income children in Los Angeles County.

DESIGN

Cross-sectional study.

SETTING

Survey data collected in 2017 and 2020 in Los Angeles County, California.

SAMPLE

Special Supplemental Nutrition Program for Women, Infants and Children (WIC) households with children ages 4-60 months.

MEASURES

Sleep duration for children 4-60 months old (less than recommended (LTR), recommended range, more than recommended (MTR)), household food insecurity (HFI), sociodemographics, and daily servings of sugar-sweetened beverages (SSB).

ANALYSIS

Multinomial logistic regression, stratified by child age, was used to calculate odds ratios (OR) and 95% confidence intervals (CI) for associations between household/child characteristics and LTR or MTR sleep compared to recommended duration among WIC participating children 4-60 months old.

RESULTS

The final sample included 3512 children ages 4-23 months and 6035 children ages 24-60 months. In the study population, 32% (3-5 years old) to 44% (4-11months) of children under 5 did not meet the recommended hours of sleep per night. HFI was associated with higher odds of LTR (OR 1.27, CI 1.12-1.45) and MTR (OR 1.46, CI 1.15-1.87) sleep among 24-60 month-old children. Each additional daily SSB serving was associated with higher odds of LTR sleep (4-23 months: OR 1.10, CI 1.02-1.19; 24-59 months: OR 1.12, CI 1.08-1.17).

CONCLUSIONS

HFI and SSB intake are associated with not getting the recommended amount of sleep among low-income WIC participating children. Nutrition assistance program participants may benefit from receiving information about recommended sleep duration for young children and how to establish sleep routines to optimize sleep duration.

Assessing the readiness to transition to adult care, perceived medication barriers, and glycemic control among teens with type 1 diabetes

AIM

This study assessed the readiness to transition (RT) from pediatric to adult care, perceived medication barriers (PMB), and glycemic control in teens with type one diabetes (T1D).

BACKGROUND

During the transition from pediatric to adult care, teens with T1D are at risk of long-term complications related to impaired adherence. With the increasing prevalence of T1D in Saudi Arabia, research is required to identify the challenges facing teens with T1D during their transition.

METHODS

This was a cross-sectional study with a convenient sample of 83 adolescents (12-17 years old) diagnosed with T1D for ≥6 months, their parents, and their pediatric endocrinologists from the pediatric endocrinology clinic in a tertiary hospital in Riyadh. The RT Questionnaire was used to measure RT, and the Medication Barriers Scale was used to measure PMB. Glycemic control was measured using hemoglobin A1c (HbA1c).

RESULTS

About 96 % of teens had HbA1c > 7 %. Male teens had higher HbA1c than female teens. Teens and their parents reported high PMB and low RT. PMB (teens), disease duration, family history of diabetes mellitus, and comorbidity were significant predictors of RT (parents). PMB (teens), teens' age, and having a family history of diabetes mellitus were significant predictors of RT (providers). RT (parents) and RT (providers) were the only significant predictors of HbA1c, with RT (providers) being the strongest predictors of HbA1c.

CONCLUSIONS

Health policy reform is required to develop national RT programs to prepare teens with T1D to take full responsibility for managing their medical conditions while ensuring adherence.

The relationship between multiple sleep dimensions and obesity in adolescents: A systematic review

Sleep is an involuntary behaviour, biologically fundamental to survival and wellbeing. However, sleep is increasingly neglected, with significant health implications. Recent research has identified associations between sleep duration, quality, timing and risk of overweight/obesity in children and adults. The aim of this review was to systematically identify and examine research that investigates the relationships between multiple objective and subjective sleep outcomes and objective adiposity measures in adolescents. A systematic review of literature, published to December 2022, was conducted using ten bibliographic databases. Search terms included objective and subjective sleep/circadian rhythm outcomes, objective adiposity measurements, and adolescents aged 8-18 years. Eighty-nine studies were included in the final review. Sleep outcomes were synthesized into three sleep domains: pre-sleep, during sleep and post-sleep outcomes. In summary, pre-sleep outcomes (including poor sleep hygiene, later chronotype and increased variability and later sleep timings) and increased sleep disturbance are consistently significantly associated with increased obesity and adiposity in adolescents. The relationship between during-sleep outcomes (sleep quality and efficiency) with adiposity and obesity measures was mixed. These findings suggest that adapting an individual's schedule to best suit chronotype preference and improving sleep hygiene, including a consistent bedtime routine, could reduce adiposity and obesity in adolescents.

Prevalence of Eating Disorders and Disordered Eating Behaviours amongst Adolescents and Young Adults in Saudi Arabia: A Systematic Review

Eating disorders (EDs) and disordered eating behaviours (DEBs) are significant health problems related to body image and weight dissatisfaction among adolescents and young adults worldwide. During this stage of sensitive development, these behaviours may hinder the optimal growth process and can consequently lead to wasting, stunting, and micronutrient deficiencies. However, there is a limited amount of literature on DEB among Arab populations, particularly in Saudi Arabia. This review aims to assess the prevalence of EDs/DEB and to develop a clear understanding of the epidemiology of such conditions among adolescents and youth in Saudi Arabia. Five databases were systematically searched and 14 papers met the inclusion criteria. The Eating Attitudes Test (EAT-26) was the predominant tool used for evaluating aberrant eating behaviours, indicating a high prevalence of EDs/DEB ranging from 10.2% to 48.1%. The highest prevalence of EDs/DEB was reported in the eastern region ranging from 29.4% to 65.5%. In terms of age and sex, the prevalence was higher among older students compared to younger school students and males reported more Eds/DEB compared to female students. These disorders are found to be prevalent in Saudi Arabia, and the risk of developing such conditions is high across the whole age range.

Examining the Impact of Socioeconomic Factors and Lifestyle Habits on Obesity Prevalence Among Male and Female Adolescent Students in Asser, Saudi Arabia

Background Understanding the relationships between obesity and lifestyle factors is essential for the effective prevention and management of obesity in youth. This study aimed to investigate the association between sociodemographic factors, lifestyle elements such as physical activity and social stress, and the prevalence of overweight and obesity among Saudi adolescents in the Aseer region. Methodology From December 2022 to March 2023, we conducted a cross-sectional study using the multi-stage stratified random sampling technique. The study included Saudi male and female adolescents aged 12-19 years attending middle and high schools. Ordinal logistic regression was used to analyze the association between the ordinal dependent variable, classified into weight groups (normal, overweight, obese), and the independent variables. Results Of the total of 512 individuals, 90.4% were aged ≥18 years, 77.5% were males, and 76.8% were urban residents. Of the studied population, 33.6% were overweight, and 20.5% were obese. The prevalence of obesity and overweight was significantly higher among males compared to females (20.9% vs. 19.1% and 36.5% vs. 23.5%, respectively). Multivariate analysis revealed the following factors to be associated with obesity and overweight: female gender (2.31, 95% CI = 1.45-3.71), age 12-17 years (0.53, 95% CI = 0.28-0.97), place of delivery (Tanoma) (2.32, 95% CI = 1.13-4.75), family size of over eight members (0.43, 95% CI = 0.24-0.74), family monthly income of over 20,000 SAR (3.79, 95% CI = 1.38-11.35), being smokers (0.26, 95% CI = 1.31-2.93), experiencing social stress (1.96, 95% CI = 1.96-2.93), engagement in physical activity less than three times a week (0.49, 95% CI = 0.32-0.75), and engagement in physical activity more than three times a week (0.36, 95% CI = 0.22-0.58). Conclusions These findings emphasize the importance of addressing demographic, socioeconomic, and lifestyle factors in combating childhood and adolescent obesity through targeted interventions.

Healthy beverage index could decrease odds of metabolic syndrome: A cross-sectional study

Some studies indicated that sugar-sweetened beverages (SSBs) were related to MetS risk, and others found no relationship between MetS and SSBs. Therefore, the present study aimed to investigate the relationship between healthy beverage index (HBI) and MetS in Iranian adults. This cross-sectional study was performed on baseline data FASA cohort. Out of 10,127 participants in the FASA cohort study, 8838 participants were included in this study. The National Cholesterol Education Program's Adult Treatment Panel (ATP) III was used for MetS definition. The HBI was calculated by a 125-item food frequency questionnaire with standard criteria. The association between HBI and MetS and its components was evaluated by univariate regression. Multivariate regression with the backward method was used for adjusting confounders. p < .05 was considered as statistically significant. Compared to the first quartile, it was observed that HBI in the last quartile was significantly related to lower odds of MetS in the multivariate analysis (odds ratio [OR] = 0.72; 95% confidence interval [CI]: 0.60-0.87, p < .001). Also, we observed a significant association between the last quartile of HBI with lower odds of high waist circumference (WC) (OR = 0.55; 95% CI: 0.45-0.67, p < .002). Our findings showed that the higher HBI score reduced MetS odds and WC. Therefore, to reduce the odds of MetS, a healthy pattern of beverage consumption, including drinking water, low-fat milk, unsweetened tea, and coffee, and reducing the consumption of SSB are recommended. More studies are needed to confirm the findings.

Sarcopenic obesity is associated with coffee intake in elderly Koreans

This study assessed the association between sarcopenic obesity (S+O+) and coffee intake inelderly Koreans. This study obtained data from the Korea National Health and Nutrition Examination Survey (KNHANES, 2008-2011), a cross-sectional and nationally representative survey conducted by the Korean Centers for Disease Control and Prevention. Of the 2,661 participants included in this study, there was a significant difference between 5.861 (95% CI 2.024-16.971) in less than one cup of coffee, and 6.245 (95% CI 2.136-18.260) in one cup of coffee, and 4.323 (95% CI 1.457-12.824) in two cups of coffee compared to three or more than cups of coffee. In contrast, in the case of sarcopenia or obesity only (S+O- or S-O+), no significant difference was found in any model. The results suggest that the elderly who consume less than one cup of coffee per day had a greater risk of S+O+ than those who consume more than three cups per day. Furthermore, there was an association between coffee intake and sarcopenia but not with obesity. Therefore, coffee intake may have prevented musculoskeletal loss in these patients.

Consumption of fruits and vegetables among adolescents in Arab Countries: a systematic review

BACKGROUND

Adolescents' consumption of fruits and vegetables is inadequate in most Arab countries, leading to a higher risk of poor health outcomes. This systematic review evaluates fruits and vegetables intake among adolescents in Arab countries, the proportion of adolescents meeting the dietary guidelines in these countries, and the dietary assessment tools used to assess fruits and vegetables intake.

METHODS

Four databases were searched, MEDLINE, PUBMED, EMBASE, and Web of Science. Studies were eligible if they reported fruit or vegetable consumption among adolescents aged 10 to 19 in 22 Arab countries. The risk of bias in the included studies was assessed by two reviewers independently using the risk of bias tool developed by Hoy et al. Data were extracted and synthesized into three categories; frequency of fruits and vegetables consumption, mean fruits and vegetables consumption, and percentage of adolescents meeting fruits and vegetables consumption recommendations.

RESULTS

The review included 44 articles utilizing 41 cross-sectional studies. Most studies were school-based, and data was collected from both males and females using self-administered questionnaires. Of those, validated questionnaires were used in 28 studies. According to the World Health Organization recommendation, most studies defined five fruits and vegetables servings as the adequacy cutoff point; other definitions were used in some studies. The reported mean consumption ranged between 6.1 times per week and 4.5 servings of fruits and vegetables per day. The proportion of those who met the recommendations of eating five servings per day ranged between 10 and 29%. Fruits were shown to have a lower daily intake than vegetables (4.2 to 53.7% for fruits and 7.8 to 66.3% for vegetables).

DISCUSSION

This review indicated inadequate fruits and vegetables consumption among adolescents in Arab countries and highlighted an increased risk of non-communicable diseases and malnutrition prevalence. A limitation was the incomparability of available data between countries. Further in-depth research on the core reasons behind adolescents' inadequacy in fruits and vegetables consumption is recommended.

Sugar Reduction Initiatives in the Eastern Mediterranean Region: A Systematic Review

This systematic review aims to identify and characterize existing national sugar reduction initiatives and strategies in the Eastern Mediterranean Region. For this purpose, a systematic review of published and grey literature was performed. A comprehensive list of search terms in the title/abstract/keyword fields was used to cover the four following concepts (1) sugar, (2) reduction OR intake, (3) policy and (4) EMR countries. A total of 162 peer-reviewed documents were identified, until the 2nd of August 2022. The key characteristics of the identified national strategies/initiatives included the average sugar intake of each country's population; sugar levels in food products/beverages; implementation strategies (taxation; elimination of subsidies; marketing regulation; reformulation; consumer education; labeling; interventions in public institution settings), as well as monitoring and evaluation of program impact. Twenty-one countries (95%) implemented at least one type of sugar reduction initiatives, the most common of which was consumer education (71%). The implemented fiscal policies included sugar subsidies' elimination (fourteen countries; 67%) and taxation (thirteen countries 62%). Thirteen countries (62%) have implemented interventions in public institution settings, compared to twelve and ten countries that implemented food product reformulation and marketing regulation initiatives, respectively. Food labeling was the least implemented sugar reduction initiative (nine countries). Monitoring activities were conducted by four countries only and impact evaluations were identified in only Iran and Kingdom of Saudi Arabia (KSA). Further action is needed to ensure that countries of the region strengthen their regulatory capacities and compliance monitoring of sugar reduction policy actions.

Toward the upscaling of school nutrition programs in Dubai: An exploratory study

Background

School nutrition programs impact the intellectual, social, and emotional development of school children, as well as their future risk of developing Non-Communicable Diseases. While many stakeholders are involved in the development, implementation, and evaluation of school nutrition programs in Dubai, United Arab Emirates, little is known about the complementarity among those stakeholders, and the means to upscale school nutrition programs while ensuring effective, efficient, and equitable implementation. Accordingly, this study aims at exploring the perceptions of a diverse group of stakeholders, positioned at differing levels of the public health and education ecosystems in the United Arab Emirates, in relation to current guidelines and practices around the planning, implementation, and evaluation of school nutrition programs in Dubai, United Arab Emirates.

Methods

The current study relied on a qualitative design, based on semi-structured key informant interviews. A total of 29 interviews were carried out. Those interviewees included leaders and directors from different institutions, decision- and policy- makers, nutritionists and dieticians, school nurses and nurse managers, and school principals and vice principals. All stakeholders were interviewed by the research team. Data was transcribed, and then thematically analyzed using the health systems' model as an analytic framework.

Results

The thematic analysis of interview data identified five interrelated themes. The first theme relates to the limited coordination across regulatory local and federal entities, and the multiplicity of guidelines issued by the different stakeholders. The challenges around the human and financial resourcing of school nutrition programs constituted the second theme. The third theme was the weakly coordinated implementation efforts. The fourth theme was the need for better performance measurement, and the fifth theme flagged the need for improved inclusiveness for health needs and cultural preferences of the diverse student body in Dubai (given that there are citizens from more than 200 nationalities co-existing in Dubai).

Conclusion

This study emphasizes that all the involved stakeholders need to better collaborate to upscale the school nutrition program in Dubai. This will require the formation of a unified governing body, which would identify and develop a single stream of resources, and sets in place a reliable, all encapsulating and equitable implementation plan along with an overarching monitoring and evaluation framework.

An agent-based model of child sugar-sweetened beverage consumption: implications for policies and practices

BACKGROUND

A strong body of evidence links young children's intake of sugar-sweetened beverages (SSBs) with myriad negative outcomes.

OBJECTIVES

Our research provides insight into whether and to what extent potential intervention strategies can reduce young children's consumption of SSBs.

METHODS

We built an agent-based model (ABM) of SSB consumption representing participants in the Project Viva longitudinal study between ages 2 and 7 y. In addition to extensive data from Project Viva, our model used nationally representative data as well as recent, high-quality literature. We tested the explanatory power of the model through comparison to consumption patterns observed in the Project Viva cohort. Then, we applied the model to simulate the potential impact of interventions that would reduce SSB availability in 1 or more settings or affect how families receive and respond to pediatrician advice.

RESULTS

Our model produced age-stratified trends in beverage consumption that closely match those observed in Project Viva cohort data. Among the potential interventions we simulated, reducing availability in the home-where young children spend the greatest amount of time-resulted in the largest consumption decrease. Removing access to all SSBs in the home resulted in them consuming 1.23 (95% CI: 1.21, 1.24) fewer servings of SSBs per week on average between the ages of 2 and 7 y, a reduction of ∼60%. By comparison, removing all SSB availability outside of the home (i.e., in schools and childcare) had a smaller impact (0.77; CI: 0.75, 0.78), a reduction of ∼40%.

CONCLUSIONS

These results suggest that interventions reducing SSB availability in the home would have the strongest effects on SSB consumption.

The clusters of health-risk behaviours and mental wellbeing and their sociodemographic correlates: a study of 15,366 ASEAN university students

Background

This study investigated, through cluster analysis, the associations between behavioural characteristics, mental wellbeing, demographic characteristics, and health among university students in the Association of Southeast Asian Nations (ASEAN) University Network – Health Promotion Network (AUN-HPN) member universities.

Methods

Data were retrieved from a cross-sectional self-administered online survey among undergraduate students in seven ASEAN countries. A two-step cluster analysis was employed, with cluster labels based on the predominant characteristics identified within the clusters. The ‘healthy’ cluster was assigned as the reference group for comparisons using multinomial logistic regression analysis.

Results

The analytic sample size comprised 15,366 university students. Five clusters of student-types were identified: (i) ‘Healthy’ (n = 1957; 12.7%); (ii) ‘High sugary beverage consumption’ (n = 8482; 55.2%); (iii) ‘Poor mental wellbeing’ (n = 2009; 13.1%); (iv) ‘Smoker’ (n = 1364; 8.9%); and (v) ‘Alcohol drinker’ (n = 1554; 10.1%). Being female (OR 1.28, 95%CI 1.14, 1.45) and being physically inactive (OR 1.20, 95%CI 1.04, 1.39) increased the odds of belonging to the ‘High sugary beverage consumption’ cluster. Being female (OR 1.21, 95%CI 1.04, 1.41), non-membership in a sports club (OR 1.83, 95%CI 1.43, 2.34) were associated with ‘Poor mental wellbeing’. Obesity (OR 2.03, 95%CI 1.47, 2.80), inactively commuting to campus (OR 1.34, 95%CI 1.09, 1.66), and living in high-rise accommodation (OR 2.94, 95%CI 1.07, 8.07) were associated with membership in the ‘Smoker’ cluster. Students living in The Philippines, Singapore, Thailand, and Vietnam had a higher likelihood of being alcohol drinkers, compared with those who lived in Brunei.

Conclusions

ASEAN university students exhibited health-risk behaviours that typically clustered around a specific health behaviour and mental wellbeing. The results provided support for focusing interventions on one dominant health-risk behaviour, with associated health-risk behaviours within clusters being potential mediators for consideration.

Time to Diagnosis and Treatment of Diabetes Mellitus among Korean Adults with Hyperglycemia: Using a Community-Based Cohort Study

OBJECTIVES

To identify the time from hyperglycemia to diabetes mellitus (DM) diagnosis and treatment, the risk factors for diabetes development, and the prevalence of comorbidities/complications in patients > 40 years of age.

METHODS

This secondary data analysis study used data from the Korean Genome and Epidemiology Study. The participants comprised 186 patients who did not have diabetes at baseline, but developed hyperglycemia at the first follow-up. The average and median periods until DM diagnosis and treatment were calculated using Kaplan-Meier survival analysis.

RESULTS

Of the 186 participants, 57.0% were men and 35.5% were 40-49 years old. The average time to DM diagnosis and treatment was 10.87 years and 11.34 years, respectively. The risk factors for the duration of DM were current smoking, body mass index (BMI), fasting blood sugar (FBS), and postprandial 2-hour glucose (PP2). The risk factors for the duration of diabetes treatment were current smoking, hypertension, BMI, FBS, and PP2. The development of one or more comorbidities or diabetes complications was identified at the time of DM diagnosis (36.5%) and DM treatment (41.4%).

CONCLUSIONS

As diabetes complications occur at the time of DM, and early treatment can impact the development of diabetes complications or mortality, it is necessary to establish a referral program so that participants presenting with high blood sugar levels in the screening program can be diagnosed and treated in a timely manner.

Association between plant-based diets and metabolic health status in adolescents with overweight and obesity

The association of plant-based diets with health status is underestimated in pediatrics. We aimed to examine the relation between plant-based diets (including overall plant-based index (PDI), healthy plant-based (hPDI) and unhealthy plant-based (uPDI)) and metabolic health status in Iranian adolescents with overweight/obesity. We conducted a cross-sectional study on 203 adolescents with overweight/obesity (12-18 years old) selected by a multistage cluster random-sampling method. Usual dietary intakes were assessed through a validated 147-item food frequency questionnaire (FFQ). Anthropometric indices and blood pressure values were measured and fasting blood samples were drawn. For classification of participants into metabolically healthy obese (MHO) or metabolically unhealthy obese (MUO) groups, two methods of International Diabetes Federation (IDF) and combination of IDF with Homeostasis Model Assessment Insulin Resistance (HOMA-IR) were applied. No significant association was observed between higher adherence to PDI and odds of MUO status defined by both IDF and IDF/HOMA-IR strategies. After adjustments for all potential confounders, adolescents in the highest tertile of hPDI, compared with those in the lowest tertile, had 85% (95% CI 0.05-0.43) and 84% (95% CI 0.05, 0.52) lower odds of being MUO based on IDF and IDF/HOMA-IR criteria, respectively. Greater adherence to uPDI was associated with odd of 3.95 (95% CI 1.41, 11.12) and 4.06 (95% CI 1.31, 12.57) of being MUO based on IDF and IDF/HOMA-IR definitions, after considering all potential confounders. Stratified analysis revealed that these associations were stronger in girls and overweight subjects. Adherence to healthy plant-based foods was inversely associated with odds of MUO status in Iranian adolescents. In contrast, unhealthy plant-based diets was directly associated with MUO in pediatrics. Further studies with prospective nature, are required to affirm these results.

A Scoping Review of Epidemiological Studies on Intake of Sugars in Geographically Dispersed Asian Countries: Comparison of Dietary Assessment Methodology

Previous systematic reviews, which focused on sugar intake and its relation with health issues, were mainly conducted in Western countries, not Asian countries characterized by differences in dietary habits and disease prevalence. The scarcity of Asian studies may be attributed to the lack of assessment tools for estimating sugar intake. To provide an overview of the epidemiological studies on sugar intake in Asian countries, with a primary focus on dietary assessment methodology for estimating sugar intake, we conducted a scoping review of the epidemiological studies estimating sugar intake in Asian countries (the United Nations' definition) and Taiwan using PubMed and Web of Science. Study quality was evaluated based on its assessment of sugar intake in the whole diet, dietary assessment methods, and data sources used for estimating sugar content. We identified 143 studies from 136 publications from Eastern (n = 63), Southern (n = 30), South-Eastern (n = 26), and Western (n = 24) Asia. Total sugars were investigated in 95 studies, while 23-30 studies investigated sucrose, fructose, added sugars, and free sugars. The main aim of the selected studies was assessment of diet-disease relations (n = 85) and estimation of dietary intake (n = 40), and 62 studies assessed sugars as the primary exposure/outcome. A total of 120 studies assessed sugar intake in the whole diet, and 62 studies used validated FFQs or multiple-day dietary assessment methods. Only 41 studies used country-specific comprehensive food-composition databases or directly measured sugar content. Only 17 studies reported high-quality data. This review elucidated a sufficient number of epidemiological studies estimating sugar intake across Asian countries; however, most studies reported low-quality data. The results from our review showed that both feasible and validated dietary assessment methods, as well as comprehensive country-specific sugar-composition databases, are essential for producing high-quality studies with accurate sugar intake to examine its association with health outcomes.

Beverage Consumption and Ulcerative Colitis: A Case-Control Study from Saudi Arabia

Background: The association between beverage intake and ulcerative colitis (UC) is not well-established, with no available data from Arab countries. Herein, we investigated the potential association of consuming coffee, tea, and carbonated soft drinks with UC among a population from Saudi Arabia. Methods: This hospital-based case-control study used data of 171 newly diagnosed UC patients and 400 patients with other gastrointestinal conditions who served as controls. All UC cases were ascertained by endoscopy, while beverage intake was assessed by a questionnaire that was completed before diagnosis. We computed odds ratios (ORs) and 95% confidence intervals (95% CIs) of UC and UC extension for frequent versus infrequent intakes of coffee, tea, and carbonated soft drinks using logistic regression. Results: Overall, 23.4% of UC patients had pancolitis, 21.1% extensive, 51.4% left-sided, and 4.1% proctitis. UC patients had a similar sex distribution to the controls but were older and had a lower BMI. After adjustment for age, sex, body mass index, and smoking history, frequent intakes of coffee and tea were associated with lower odds of UC: 0.62 (0.42, 0.91) and 0.53 (0.35, 0.79), respectively. On the other hand, frequent intakes of carbonated soft drinks were associated with increased odds of UC: 9.82 (6.12, 15.76). The frequency of beverage consumption was not associated with UC extension. Conclusion: UC was negatively associated with frequent coffee and tea consumption but positively associated with frequent carbonated soft drink intake in Saudi people. More population-based prospective cohort studies are needed to confirm our findings.

Development of a Food Frequency Questionnaire for Assessing Habitual Intake of Free Sugar Among Children in Saudi Arabia

The World Health Organization emphasizes the urgency to assess and limit the intake of free sugar (FS) among individuals in order to prevent several non-communicable diseases. However, data regarding intake of FS are lacking in Saudi Arabia and in the Middle East. A reliable valid tool is needed to assess children's habitual intake of FS. Thus, we aimed to develop and validate a food frequency questionnaire (FFQ) that assesses children's habitual intake of FS in Saudi Arabia. In this cross-sectional study, 424 healthy Saudi children ages 6–12 years were included using river sampling method. Sociodemographic data and contact information were collected from mothers using an online survey. Dietary data were collected using 24-h dietary recalls (reference method) and a semi-quantitative FFQ through phone interviews. Items and food groups included in the initial draft of the FFQ were adopted from previous work. Content validity was done to the FFQ with total of 12 food groups and 41 food items. Next, a pilot study was conducted to estimate the sample size needed for the study and to ensure that all items reported in the 24-h dietary recalls were included in the final draft of the FFQ. Finally, data were collected to assess the validity and reliability of the FFQ at the population level. Mean intake of FS assessed by the FFQ was significantly higher than that assessed by the 24-h dietary recalls. Spearman's correlation between total FS assessed by the FFQ and 24-h dietary recall was positively low (rs = 0.30, p &lt; 0.001). The coefficient alpha indicated an acceptable level of internal consistency (α = 0.74, p &lt; 0.001). Test-retest reliability for total FS intake assessed by the FFQ was positively high (rs = 0.82). A slight agreement between FS intake assessed by the FFQ and the 24-h dietary recall was seen among the study sample (κ = 0.21, p &lt; 0.001). The newly developed FFQ was found to be reasonably valid in assessing children's habitual intake of FS in Saudi Arabia. Validating the instrument among older population in Saudi Arabia is warranted.

Consumption of Free Sugar Predicts Nutrient Intake of Saudi Children

Data concerning the association between free sugar intake and nutrient intake in children in the Middle East are not available. This study aimed to explore the association between the consumption of free sugar and nutrient intake among Saudi children. A cross-sectional study included 424 Saudi children ages between 6 and 12 years old and their mothers. An online survey collected sociodemographic data from mothers. Trained data collector personal contacted mothers to arrange for a phone interview in order to collect 24-h dietary recall to assess the dietary intake of children. Only 0.90% of children consumed free sugar within the recent recommendation of the World Health Organization (WHO) of <5% of total energy intake, whereas 10.6% of children consumed free sugar <10% of total energy intake. The percentage of free sugar intake was negatively associated with total energy intake. Multiple linear regression analysis of free sugar consumption and nutrient intake adjusted for children's age and sex indicated that a higher percentage of free sugar intake significantly predicted lower intake of saturated fat, fiber, sodium, potassium, calcium, iron, zinc, and vitamin B₁₂. Excessive intake of free sugar predicted a lower intake of many essential nutrients. Interventions that aim to reduce the intake of free sugar are urgently needed in order to improve diet of growing children. Future research to explore top food sources of free sugar is needed to establish effective interventions that aim to limit free sugar intake among children.

Distinct Impact of Natural Sugars from Fruit Juices and Added Sugars on Caloric Intake, Body Weight, Glycaemia, Oxidative Stress and Glycation in Diabetic Rats

Although fruit juices are a natural source of sugars, there is a controversy whether their sugar content has similar harmful effects as beverages’ added-sugars. We aimed to study the role of fruit juice sugars in inducing overweight, hyperglycaemia, glycation and oxidative stress in normal and diabetic animal models. In diabetic Goto-Kakizaki (GK) rats, we compared the effects of four different fruit juices (4-weeks) with sugary solutions having a similar sugar profile and concentration. In vitro, the sugary solutions were more susceptible to AGE formation than fruit juices, also causing higher postprandial glycaemia and lower erythrocytes’ antioxidant capacity in vivo (single intake). In GK rats, ad libitum fruit juice consumption (4-weeks) did not change body weight, glycaemia, oxidative stress nor glycation. Consumption of a matched volume of sugary solutions aggravated fasting glycaemia but had a moderate impact on caloric intake and oxidative stress/glycation markers in tissues of diabetic rats. Ad libitum availability of the same sugary solutions impaired energy balance regulation, leading to higher caloric intake than ad libitum fruit juices and controls, as well as weight gain, fasting hyperglycaemia, insulin intolerance and impaired oxidative stress/glycation markers in several tissues. We demonstrated the distinct role of sugars naturally present in fruit juices and added sugars in energy balance regulation, impairing oxidative stress, glycation and glucose metabolism in an animal model of type 2 diabetes.

Changes in Sugary Beverage Consumption and Public Perceptions in Upstate New York After Implementation of a Community Awareness Campaign and Healthier Vending Strategies

OBJECTIVE

We evaluated the impact of a community-based healthy beverage procurement and serving practices program, and educational media campaign, on residents' behaviors and beliefs regarding sugary beverages.

DESIGN

Repeated cross-sectional population surveys in 2013 and 2014 were conducted, as well as semistructured interviews with key informants. We employed multivariate differences-in-differences regression analysis, adjusting for demographics and weight status, using the survey data. Key informant interviews were reviewed for common themes.

SETTING

Three rural counties in upstate New York with high prevalence of children living in poverty and childhood obesity.

PARTICIPANTS

Residents of Broome, Cattaraugus, and Chautauqua, with Chemung as a control, reached through cross-sectional random-digit-dial landline and cellular telephones, and practitioners involved in intervention implementation.

INTERVENTION

Community organizations were encouraged through presentations to leadership to adopt healthier vending policies, providing more low- and no-sugar options, and were provided assistance with implementation. In addition, a media campaign supported by presentations to the public aimed to educate residents regarding the health consequences of sugary beverage consumption.

OUTCOME MEASURES

The survey measured population demographics and sugary beverage consumption frequency, availability, beliefs about harmfulness, and support for regulation, pre- and postintervention. Key informant interviews elicited perceived program challenges and successes.

RESULTS

Compared with temporal trends in the control county, availability of regular soda in the intervention counties decreased (differences-in-differences estimator: β = -.341, P = .04) and support for regulation increased (differences-in-differences estimator: β = .162, P = .02). However, there were no differences regarding beliefs about harmfulness or consumption. Practitioners confirmed that the intervention increased awareness but was insufficient to spur action.

CONCLUSION

Although public education on the harmfulness of sugary beverages and provision of healthier options in some vending machines successfully impacted soda availability and support for regulation, it did not reduce consumption. This intervention seems promising but should be paired with other community-based interventions for a more comprehensive approach.

Sugar-sweetened beverage consumption and bone health: a systematic review and meta-analysis

BACKGROUND

Current evidence demonstrate that sugar-sweetened beverages (SSBs) and bone health are related; however, there has been only a few reviews on the link between SSBs and bone health. A systematic review and meta-analysis was performed to investigate the association between SSBs consumption and bone health in chidren and adults.

METHODS

Relevant studies of SSBs and bone health published up to 15 March 2021 were searched using PubMed, the Web of Science, Cochrane Library, and a reference search. A random-effects meta-analysis was conducted to estimate the standardized mean difference (SMD). Subgroup analyses were performed to identify whether effects were modified by age, sex, measured skeletal sites, type of SSBs, and SSBs intake questionnaire.

RESULTS

Twenty-six publications including 124,691 participants were selected on the review. The results from this meta-analysis showed a significant inverse association between SSBs intake and bone mineral density (BMD) in adults (ES: -0.66, 95% CI: - 1.01, - 0.31, n = 4312). Eighteen of the 20 studies included in the qualitative-only review in children and adults supported the findings from the meta-analysis. When subgroup analysis was performed according to skeletal site, a large effect was found on whole body BMD (ES: -0.97, 95% CI: - 1.54, - 0.40). There was a moderate effect on BMD in females (ES: -0.50, 95% CI: - 0.87, - 0.13). There was a moderate or large effect on BMD in individuals aged under 50 years (under 30 years: ES: -0.57, 95% CI: - 0.97, - 0.17; 30 to 50 years: ES: -1.33, 95% CI: - 1.72, - 0.93). High consumption of carbonated beverages had a moderate effect on BMD (ES: -0.73, 95% CI: - 1.12, - 0.35).

CONCLUSION

The meta-analysis showed that SSBs consumption such as carbonated beverages were inversely related to BMD in adults. Qualitative review supported the results of meta-analysis.

TRIAL REGISTRATION

This review was registered in the PROSPERO database under identifier CRD42020164428 .

Barriers and Facilitators Associated with Physical Activity in the Middle East and North Africa Region: A Systematic Overview

Increasing physical inactivity levels in the Middle East and North Africa (MENA) region is a public health concern. We aimed to synthesize barriers and facilitators to physical activity and make appropriate recommendations to address physical inactivity. We conducted an overview of systematic reviews on physical activity barriers and facilitators in 20 MENA countries by systematically searching MEDLINE/PubMed and Google Scholar for systematic reviews published between 2008 and 2020. Our overview included four systematic reviews and 119 primary studies with data from 17 MENA countries. Lack of suitable sports facilities, time, social support and motivation, gender and cultural norms, harsh weather, and hot climate were the most commonly reported barriers to physical activity. Socio-demographic factors negatively associated with physical activity participation include advanced age, being female, less educated, and being married. Motivation to gain health benefits, losing/maintaining weight, being male, dietary habits, recreation, and increased Body Mass Index are positively associated with increased levels of physical activity. Interventions promoting physical activity in MENA should target schoolchildren, women and girls, working parents, and the elderly. Country-specific sociocultural and environmental factors influencing physical activity should be considered in the design of interventions. Current and future policies and national interventions must be consistently evaluated for effectiveness and desired outcomes.

Prevalence and social determinants of overweight and obesity in adolescents in Saudi Arabia: A systematic review

Obesity in adolescents has a serious impact later in life in the form of disturbances in health and wellbeing. We aimed to evaluate the prevalence of overweight and obesity (Ow/Ob) in Saudi adolescents and to construct an ecological model of social determinants (SDs) of Ow/Ob and evaluate current evidence of their effect on Saudi adolescents. A systematic review of literature reported up until 31 December 2018 on Ow/Ob and factors that can influence them in Saudi adolescents was conducted. Fifty-one studies with n = 97 666 adolescents (55.6% males) were reviewed. The prevalence of Ow/Ob started off high and continued to increase over time. Most of the 49 reviewed SDs reports, from 19 studies, showed positive association between SDs constructed ecological model and Ow/Ob in Saudi adolescents. The prevalence of Ow/Ob among adolescents is a major public health problem in Saudi Arabia, is growing at an alarming rate and SDs play a significant role in this problem, and should be considered in all strategies targeting it. The constructed ecological model for SDs of Ow/Ob in adolescents can serve as a useful exploratory tool that helps investigating the multi-faceted aetiology of adolescent Ow/Ob and facilitates the development of effective intervention and prevention programmes.

Increased adiposity in children with obesity is associated with low red blood cell omega-3 fatty acid status and inadequate polyunsaturated fatty acid dietary intake

The association between total dietary fat intake and measures of body fatness in children with obesity remains inconsistent. This study aimed to determine whether dietary long-chain polyunsaturated fatty acids (LCPUFA) and LCPUFA status relate to body composition in children with obesity. Children (n = 63, 9.0 ± 0.2 year, BMI Z-score 3.1 ± 0.2) were divided into tertiles of percentage body fat assessed by dual-energy X-ray absorptiometry. Diet was assessed 3-days food diaries. Fatty acid proportions in red blood cells (RBC) were measured by gas chromatography. Data stratified by sex and Tanner stages were compared with a MIXED model ANOVA. Associations between RBC fatty acid status and dietary intakes were examined with Spearman correlation. Moderate correlations were observed between RBC eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) proportions, dietary EPA and DHA (r = 0.39, P < .05) as well as fish servings (r = 0.33, P < .05). Dietary LCPUFA did not differ among tertiles. Children in tertile 3 had lower RBC α-linolenic acid (-40%) and EPA + DHA (-15%) proportions adjusted for age, Tanner stages and race compared with tertile 1. The lower omega-3 LCPUFA status in children with greater adiposity is consistent with suboptimal intakes of omega-3 LCPUFA and fish in the diet.

Impact of Sugary Food Consumption on Pregnancy: A Review

Obesity in pregnancy has been directly associated with an increased risk of almost all pregnancy complications such as gestational hypertension, preeclampsia, gestational diabetes mellitus (GDM), and premature delivery. Thereby, according to current evidence available, life-style interventions to prevent pre-pregnancy overweight and obesity in women of fertile age are necessary to reduce the negative impact of obesity on mother and child health. Unhealthy dietary patterns, together with the increased consumption of processed foods rich in simple sugar and sweeteners are some of the responsible, among others, for the increase in obesity rates during the last years. Nevertheless, how its consumption can affect pregnancy outcomes and long-term children’s health is still uncertain. This review aims to collate the available evidence about the consequences of unhealthy dietary patterns and sugary products consumption, including sweeteners, during pregnancy for obesity in childhood and mid-childhood. High simple sugar intake during gestation may contribute to an excessive gestational weight gain (GWG) as well as to develop other pregnancy complications such as GDM, preeclampsia and preterm birth. The heterogeneity of study populations, sample size, different approaches to measure GWG, GMD, preeclampsia, and birth weight, among other conditions, might explain the divergences observed among studies. Therefore, large, well-designed intervention-controlled trials with biological biomarkers to ensure dietary adherence are necessary to evaluate the effectiveness of lifestyle interventions in order to provide effective nutritional advice.

Analysis of gum bleeding among children aged 12-15 years in Jiangxi Province and related influencing factors

OBJECTIVE

To study the prevalence of gum bleeding in children aged 12-15 years in Jiangxi Province and related influencing factors for the development of effective prevention and treatment strategies.

METHODS

A multistage cluster stratified sampling method was used to select 8,160 children aged 12-15 years for this study. Enrolled children completed a set of survey questionnaires covering children's gender, age, parents' educational level, oral health knowledge scores, attitude scores, and brushing habits in addition of dental examination. All the data were analyzed using the chi-square test and logistic regression.

RESULTS

Among 8,160 children, the gum bleeding rate was 66.5 percent (95% CI: 65.8%-68.1%). The gum bleeding rate in urban children (68.0 percent) was higher than that in rural areas (65.0 percent) (P < 0.01); the gum bleeding rate in boys (67.6 percent) was higher than that in girls (65.4 percent) (P < 0.05). The results of binary logistic regression analysis showed that age, urban and rural areas, mother education, knowledge score, attitude score, and brushing frequency were all important factors affecting gum bleeding.

CONCLUSION

This study showed that incidence of gum bleeding in Jiangxi children is high which is affected by their age, mother's education, and several other factors. These new findings form the baseline information essential for the development of more effective approaches to prevent and control children gum bleeding in Jiangxi and other regions in the future.

Food Consumption Patterns and Nutrient Intakes of Children and Adolescents in the Eastern Mediterranean Region: A Call for Policy Action

The Eastern Mediterranean Region (EMR) has witnessed significant social and economic changes that may have influenced the diet of children and adolescents, and increased the risk for obesity and malnutrition in this age group. This review aims to characterize and assess food consumption patterns and nutrient intakes amongst school-aged children (5-10 years) and adolescents (10-19 years) in countries of the EMR. Electronic databases (MedLine, PubMed, Scopus, and Google Scholar) were searched for relevant articles published between 2005 and 2020; international organizations and governmental websites were also searched. Available studies documented low intakes of fruits, vegetables and fiber, inadequate consumption of water, milk and dairy products, coupled with high intakes of fat, saturated fat, and sugar sweetened beverages, as well as a frequent consumption of energy-dense, nutrient poor foods such as sweet and savory snacks. Micronutrient inadequacies were also observed, particularly for calcium, iron, zinc and vitamins A, D, C, and folate. Acknowledging the impact that nutrition may have on building societies and transforming the lives of children, adolescents and their families, there is a crucial need for a food system approach in developing and implementing national and regional policies and interventions aimed at improving the diet of children and adolescents.

Difference on the prevalence, patterns and awareness of soft drink consumption among male and female Arab students

BACKGROUND

The increase in soft drink (SD) consumption is emerging as a serious health issue. Our aim is to explore the prevalence and awareness regarding SD consumption among Saudi students.

METHODS

This cross-sectional study included 1000 apparently healthy Saudi students (527 males, 473 females) aged 16-23 years. A designed questionnaire including various sections was used to obtain the required information.

RESULTS

The BMI and frequency of SD consumption were significantly higher in males (P < 0.001) than females, whereas, females exhibited higher awareness and knowledge regarding SD consumption than males. The SD consumption in females was due to society, taste, availability and markets, whereas in males it was due to cheap price. Females support the implementation of new policies to prevent consumption of SD.

CONCLUSIONS

Arab students exhibited a high prevalence of SD consumption especially in males. Although females showed more awareness and knowledge about SD, various misconceptions were notable in both sexes. New policies, health promotion campaigns must be organized to raise awareness among children and parents. Parents and health educators should motivate and encourage the children to consume more water in the context of a healthy balanced diet.

Contribution of Home and School Environment in Children's Food Choice and Overweight/Obesity Prevalence in African Context: Evidence for Creating Enabling Healthful Food Environment

This review aimed primarily to investigate the current trends of overweight and obesity in school children in the African context, secondly to explore the contribution of home and school environments on the children’s food choices and lastly suggesting measures for creating a healthier food environment. Despite the increase in overweight and obesity among school children, empirical evidence on their determinants in the African context is scarce, thus calls for consideration of home and school environments. A literature search was conducted between October and December 2018 using Medline (PubMed), Directory of Open Access Journals, Google Scholar, manual search and “grey” literature. This review included articles published between the 1st January 2008 and 30th June 2018. Out of 343 articles, 49 were included for the full text reading after meeting the inclusion criteria. Five reports from grey literature were also included. Results show that the prevalence of overweight and obesity among school children in Africa is increasing and ranges from <5% to >40% in the 10-year period in which the review was taken. High socio-economic status, urban residence and female gender predicted higher prevalence of overweight/obesity. Few reviewed articles on the contribution of home and school environments on children’s food choices showed a shred of evidence, thus calls for further research to address this gap. This review found an increasing prevalence of overweight and obesity in school children in Africa. Therefore, further investigation of home and school environment is imperative to curb the increase in the magnitude of overweight and obesity.

Sugar-sweetened beverage consumption is associated with visceral fat in children

Sugar-sweetened beverage (SSB) consumption has been associated with visceral fat partitioning in adults; however, the underlying mechanisms in childhood remain unclear and warrant exploration. This cross-sectional study aimed to investigate the association between SSB consumption and body fat in children aged 9-13 years and the potential modifying effect of children's sex and serum cortisol levels. A sample of 2665 Greek schoolchildren participated in the 'Healthy Growth Study', and anthropometric, body composition, dietary intake and serum cortisol data were assessed. SSB consumption was defined as low (<1 serving/d), medium (1-2 servings/d) or high (>2 servings/d). We used linear regression models to assess the association between SSB consumption and measures of adiposity and to assess effect modification; models were stratified by sex and tertiles of morning serum cortisol. A significant positive association was observed between high SSB consumption and visceral adipose tissue (VAT) (β = 1·4, 95 % CI 0·4, 2·3, P = 0·01) but not BMI or BMI z-score. When stratified by sex, the association was observed in boys (β = 1·8, 95 % CI 0·3, 3·4, P = 0·02) but not in girls. When stratified by cortisol levels, SSB consumption was associated with VAT in children with cortisol levels in the lowest tertile (β = 2·8, 95 % CI 1·0, 4·6, P < 0·01). These results indicate that increased SSB consumption is associated with visceral adiposity in schoolchildren and this association may be modified by sex and morning serum cortisol. To prevent VAT accumulation and concomitant disease risk, dietary interventions should target SSB consumption during childhood.

Urgent Need for Adolescent Physical Activity Policies and Promotion: Lessons from "Jeeluna"

Physical inactivity is a growing concern in Kingdom of Saudi Arabia (KSA) and globally. Data on physical activity (PA) trends, barriers, and facilitators among adolescents in KSA are scarce. This study aims to identify PA trends amongst adolescents in KSA and associated health and lifestyle behaviors. Data from “Jeeluna”, a national study in KSA involving around 12,500 adolescents, were utilized. School students were invited to participate, and a multistage sampling procedure was used. Data collection included a self-administered questionnaire, anthropometric measurements, and blood sampling. Adolescents who performed PA for at least one day per week for >30 min each day were considered to “engage in PA”. Mean age of the participants was 15.8 ± 0.8 years, and 51.3% were male. Forty-four percent did not engage in PA regularly. Only 35% engaged in PA at school, while 40% were not offered PA at school. Significantly more 10–14-year old than 15–19-year-old adolescents and more males than females engaged in PA (<0.01). Mental health was better in adolescents who engaged in PA (<0.01). Adolescents who engaged in PA were more likely to eat healthy food and less likely to live a sedentary lifestyle (<0.01). It is imperative that socio-cultural and demographic factors be taken into consideration during program and policy development. This study highlights the urgent need for promoting PA among adolescents in KSA and addressing perceived barriers, while offering a treasure of information to policy and decision makers.

Physical activity and sedentary behaviour in the Middle East and North Africa: An overview of systematic reviews and meta-analysis

To support the global strategy to reduce risk factors for obesity, we synthesized the evidence on physical activity (PA) and sedentary behaviour in the Middle East and North Africa (MENA) region. Our systematic overview included seven systematic reviews reporting 229 primary studies. The meta-analysis included 125 prevalence measures from 20 MENA countries. After 2000, 50.8% of adults (ranging from 13.2% in Sudan to 94.9% in Jordan) and 25.6% of youth (ranging from 8.3% in Egypt to 51.0% in Lebanon) were sufficiently active. Limited data on PA behaviours is available for MENA countries, with the exception of Gulf Cooperation Council countries. The meta-regression identified gender and geographical coverage among youth, and the PA measurement as predictors of PA prevalence for both adults and youth. Our analysis suggests a significant PA prevalence increase among adults over the last two decades. The inconsistency in sedentary behaviour measurement is related to the absence of standardized guidelines for its quantification and interpretation. The global epidemic of insufficient PA is prevalent in MENA. Lower PA participation among youth and specifically females should be addressed by focused lifestyle interventions. The recognition of sedentary behaviour as a public health issue in the region remains unclear. Additional data on PA behaviours is needed from low- and middle-income countries in the region.

Prevalence and correlates of fruit and vegetable consumption among adolescents in Laos

The study aimed to estimate the prevalence and correlates of fruit and vegetable (FV) intake among adolescents in the "2015 Laos Global School-Based Student Health Survey (GSHS)". The study sample consisted of 3,683 school adolescents with a median age of 16 years from Laos that responded to the 2015 cross-sectional GSHS. The prevalence of inadequate fruit consumption (<2/day) was 74.0%, inadequate vegetable consumption (<3/day) 78.5%, and inadequate FV consumption (<5/day) 83.7%. In adjusted logistic regression analysis, physical inactivity (adjusted odds ratio = AOR: 1.43, 95% confidence interval=CI, 1.061.93) was positively, and being overweight or obese (AOR: 0.65; 95% CI, 0.450.95), soft drink consumption (AOR: 0.55; 95% CI, 0.440.69), fast food consumption (AOR: 0.59; 95% CI, 0.470.74), and peer support (AOR: 0.69; 95% CI, 0.540.88) were negatively associated with inadequate FV consumption. A high proportion of inadequate FV consumption was found and strategies to increase FV consumption in this population may take into account sociodemographic, lifestyle, peer and parental factors.

Correlates of sugar-sweetened beverage consumption of Malaysian preschoolers aged 3 to 6 years

Background

There is little information about the diet, lifestyle and parental characteristics associated with habitual sugar-sweetened beverage (SSB) consumption in Asian children. The aim of the present study was to assess cross-sectional associations between habitual SSB consumption and preschoolers’ diet, physical activity, sedentary behaviour as well as parental and child characteristics in Malaysian preschoolers aged 3 to 6 y.

Methods

A total of 590 preschoolers, comprising 317 boys and 273 girls were included. Pre-pilot parental questionnaires were used to assess diet, physical activity (PA) and sedentary behaviour practices and anthropometry was assessed in preschoolers and their parents.

Results

Multiple logistic regression analyses showed that preschoolers with more frequent weekly intake of snacks [OR 2.7; 95% CI, 1.6–4.4; p < 0.001] and monthly fast food consumption [OR 3.5; 95% CI, 1.9–6.3; p < 0.001], were associated with higher SSB intake (≥5 days in a week), after adjustments of potential confounders. Preschoolers with higher daily fruit and vegetable intake had lower SSB intake [OR 0.4; 95% CI, 0.2–0.8; p = 0.011]. A positive association of higher weekly vigorous PA [OR 2.0; 95% CI, 1.1–3.7; p = 0.030] and daily screen-based practices [OR 2.0; 95% CI, 1.2–3.6; p < 0.001] on habitual SSBs intake was also substantiated.

Conclusion

Multiple diet, physical activity and sedentary behaviour factors were significantly associated with SSB intake among Malaysian preschoolers. Continued effort is required to encourage healthier beverage choices, as well as healthy diet and active lifestyle practices among children during the critical early years of growth and development.

Snack food consumption among Bangladeshi children, supplementary data from a large RCT

Childhood obesity has been associated with consumption of energy-dense foods such as caloric beverages and fast foods. Many low- and middle-income countries like Bangladesh are now experiencing a rising problem of noncommunicable diseases along with the long-standing problem of stunting and undernutrition. WASH Benefits Bangladesh was a large community-based cluster randomized controlled trial conducted in rural Bangladesh. Study clusters were randomized into seven arms: single nutrition (N); water (W); sanitation (S); hygiene (H); combined water, sanitation, and hygiene (WSH); WSH and nutrition (N + WSH); and a double sized control (C). Nutrition intervention messages included four promotional components: maternal nutrition, breastfeeding, complementary feeding, and lipid-based nutrient supplements. The World Health Organization infant food frequency questionnaire (24-hr recall and 7-day recall) was administered at Year 1 and Year 2 of intervention. The likelihood of any snack food consumption was significantly lower (odds ratio 0.37: 95% confidence interval [0.28, 0.49]) in the nutrition intervention arms compared to the control arm in Year 2 follow-up. In addition, in the water intervention arm, fewer children (about 50% less) consumed soft drinks, but not the other sugar-sweetened beverages, compared with control in Year 2. There were no other differences between groups. Simple messages about balanced diet and feeding family foods were effective in lowering commercially produced snack food consumption of the young children in low-income rural communities of Bangladesh. Provision of safe water apparently encouraged mothers to reduce offering unhealthy beverages to the young children.

Adherence to healthy diet is related to better linear growth with open growth plate in adolescent girls

Nutritional status can affect the linear growth of bones during puberty by affecting growth plate (GP) chondrocytes. We hypothesized that there is a relationship between dietary patterns and bone age on girls who have experienced height loss. This cross-sectional study was conducted on 350 girls aged 12-13 years with open GP, and major dietary patterns were determined using the factor analysis method. Dual-energy x-ray absorptiometry measurement of participant's wrist was performed to determine GP openness and bone age. In the present study, 70.3% of participants had bone age below chronological age. Three major dietary patterns-healthy, high sugar and salt, and Western diet-were identified using findings of dietary intake. Adherence to the healthy diet led to significant increase in height, weight, body mass index, and other components of body composition such as lean body mass (P < .001). Among these dietary patterns, we found only a significant association between healthy diet and difference between bone and chronological age (B = -0.106). In the present study, adherence to a healthy diet was associated with increase in bone age (P = .02). Healthy dietary pattern with an emphasis on enough intake of plant protein and white meat was associated with better linear growth.

Eating Habits Among Medical Students at King Abdulaziz University, Jeddah, Saudi Arabia

Background

Eating habits are a major concern with regard to the health status of university students. This study aimed to identify patterns of eating habits among undergraduate medical students and to investigate their relationship to sociodemographic, socioeconomic, and psychological factors.

Methods

This cross-sectional study included 378 undergraduate medical students aged 19-26 from the Faculty of Medicine at King Abdulaziz University, Jeddah, Saudi Arabia. Students were in their second through sixth academic year. Data were gathered with a self-administered questionnaire encompassing questions on sociodemographics, eating habits, and psychological factors.

Results

Eating habits score was much lower among students who were smokers, lived in rented places, lived alone, had separated parents, and did not exercise regularly. In multivariate analysis, multiple psychological factors, such as living alone and stressed, were found to be associated with eating patterns.

Conclusion

A majority of undergraduate medical students had unhealthy eating patterns, and socioeconomic and psychological elements were significantly affecting eating patterns.

Association between soft drink consumption, gastric reflux, dental erosion, and obesity among special care children

OBJECTIVES

This study assessed the association between soft drink consumption, gastric reflux, dental erosion, and obesity among special care children.

MATERIALS AND METHODS

A total of 350 special care children (male-131, female-219) mean age of 12.6 (± 2.6) years were included. Detection of dental erosion was performed according to the World Health Organization criteria. The medical evaluation assessed body mass index (BMI). With appropriate sample weighting, relationships between dental erosion prevalence and obesity were assessed using multivariable logistic regression.

RESULTS

Overall prevalence of dental erosion was 36%. Mean BMI for entire study population was 24.7 (± 7.8). Regression analysis showed strong association between dental erosion prevalence and consumption of soft drinks (adjusted odds ratio = 1.8; 95% CI = 0.71-2.92, P < .05), bulimia (adjusted odds ratio = 2.27; 95% CI = 0.99-4.28, P < .001), and gastric reflux (adjusted odds ratio = 2.24; 95% CI = 0.82-4.1, P < .001). Bivariate analysis showed high prevalence of dental erosion among obese children compared to children with normal weight (P = .04).

CONCLUSION

The present study demonstrated a significant association between dental erosion prevalence and consumption of soft drinks and gastric reflux among special care children.

Characterizing Micro-scale Disparities in Childhood Obesity: Examining the Influence of Multilevel Factors on 4-Year Changes in BMI, Healthy Eating, and Physical Activity, Among a Cohort of Children Residing in Disadvantaged Urban Enclaves

The childhood obesity epidemic in the United States disproportionately affects minority, low-income populations. Hispanics have one of the highest childhood obesity rates, and are the fastest growing population subgroup in the country. Past research has examined disparities in the occurrence of obesity, healthy eating, and physical activity at a macro-geographic level, with less emphasis on examining the multilevel, micro-scale determinants of childhood obesity in disadvantaged urban ethnic enclaves. The aim of our study was to identify child-, parental-, familial-, community-, and neighborhood-level factors associated with differences in 4-year changes in BMI, healthy eating, and physical activity, among children residing in low-income, predominantly Hispanic urban enclaves in Austin, Texas. This analysis used data from the Go Austin! Vamos Austin! (GAVA) Evaluation study, a cohort with 4 years of follow-up from 313 child-caregiver dyads. The dependent variables were change categories denoting 4-year increase, decrease, or no change in Body Mass Index (BMI) percentile, fruit and vegetable intake, and physical activity, among child participants. The independent variables were factors at multiple levels of the socio-ecological model: child, parental, familial, community, and environmental. Multinomial logistic regression models were used to estimate the odds of children being in the “increasing” or “decreasing” categories for the three dependent variables (vs. “no change”), in association with the studied independent variables. The results showed that among children residing in this low-income, predominantly Hispanic urban enclave, weight gain prevention and weight loss have different determinants. We identified relevant micro-scale disparities, and micro-level factors of influence on child BMI and its related health behaviors, at all levels of the socio-ecological model. Our results revealed evidence, through the characterization of positive deviance cases (children for whom decreases in BMI, increases in fruit and vegetable intake, or increases in physical activity were observed) which could potentially help mitigate established unhealthy habits among high need populations. Factors associated with positive deviance for BMI (decreases in child BMI) included male child sex (OR: 0.33, 95% CI: 0.12–0.83) and living in a food-insecure household (OR: 0.24, 95% CI: 0.13–0.79). Our findings may inform the design of obesity prevention interventions in these types of disadvantaged urban Hispanic enclaves.

Dietary Patterns, Exercise, and the Metabolic Syndrome Among Young People in Urban Pakistan (Lahore)

Background: Increasing urbanization, mechanization, and rural-to-urban migration has led to deranged sleeping patterns, surplus energy intake, and sedentary lifestyles in South Asian young people. This shift poses an insidious health risk for the development of metabolic syndrome (MetS). Early detection is needed because in the South Asian population, this syndrome carries an increased risk of comorbidities compared to people without the syndrome. This study was designed to elucidate the prevalence of MetS and its risk factors in young people in urban areas of Pakistan. Methods: A cross-sectional study was conducted in four undergraduate institutions in Lahore, Pakistan. Five hundred and nine young people participated, and each provided their informed consent for the collection of data on their demographic, physical, and biochemical characteristics along with information on their dietary, sleep, and physical activity habits. Results: Most participants reported consuming greater-than-recommended amounts of protein and smaller-than-recommended amounts of vegetables and fruits. The International Diabetes Federation criteria for MetS were fulfilled by 6.1% of the students. Hypertension (67.7%) and hypo-HDL-emia (64.5%) were the most common risk factors. More than 50% of the respondents slept fewer hours per day than recommended, and 33% had a sedentary lifestyle. Men, participants with a family history of metabolic illness and those with low physical activity levels had higher odds of a positive result on screening for MetS. Conclusions: The early detection of MetS and early identification of probable risk factors may make beneficial contributions to both public health and clinical interventions directed at high-risk individuals. Establishing and using cutoff values for modified waist circumference and specific body mass index in Asian populations may aid in early detection.

Fast food consumption and its associations with heart rate, blood pressure, cognitive function and quality of life. Pilot study

Background

To investigate the relationship of fast food consumption with cognitive and metabolic function of adults (18-25 years old) in Riyadh, Kingdom of Saudi Arabia.

Materials and Method

This cross-sectional study was conducted at the College of Medicine at King Khalid University Hospital, Riyadh, Saudi Arabia. The conventionally recruited subjects underwent an evaluation that included demographic data, quality of life (wellness, stress, sleepiness, and physical activity), mini-mental status examination, and the frequency of fast food consumption. To investigate metabolic function, blood was drawn to evaluate serum HDL, LDL, cholesterol, and triglyceride levels. Cognitive function was assessed by the Cambridge neuropsychological test automated battery. The participants were divided into 2 groups based on fast food consumption: those who consumed fast food 3 times per week or less (Group 1) and those who consumed fast food more than 3 times per week (Group 2).

Results

The mean diastolic blood pressure in Group 1 and Group 2 was 72 mmHg and 77 mmHg, respectively, a significant difference (p = 0.04). There was no significant difference for cognitive function and quality of life between the two groups. There was significant correlation of HDL with AST correct mean latency and the AST correct mean latency congruent (p = 0.02, p = 0.01, respectively) and TC with diastolic blood pressure (p = 0.003).

Conclusions

We concluded that fast food consumption has an effect on blood pressure but has no direct effect on cognition or quality of life.

Childhood obesity in relation to sweet taste perception and dental caries - a cross-sectional multicenter study

Background

Obesity is a multifactorial disease that is increasing worldwide and is caused by different environmental and genetic factors, with an increase in the consumption of high-energy–containing food and a decrease in physical activity constituting two of the main reasons. Sweet taste perception may have an effect on the subject’s dietary choices and affect his or her predisposition to obesity.

Objectives

The aim was to study the sweet taste perception and dental caries in relation to body mass index (BMI) in 13–15-year-old schoolchildren from three different countries and to compare the BMI among the countries.

Design

The sweet taste perception level, determined as the sweet taste threshold and preference, was assessed in a total of 669 schoolchildren from Italy, Mexico and Saudi Arabia, examined in school settings. Height and weight were collected and BMI was calculated, after which the children were grouped as underweight, normal, overweight, and obese. For caries registration, the International Caries Detection and Assessment System and Decayed Missing Filled Surfaces indices were used.

Results

A statistically significant difference was found for BMI among the children from the three countries (p < 0.001), with the highest mean found among Saudi children, followed by Mexican and Italian children. A statistically significant difference regarding sweet taste threshold when comparing the BMI groups was only found for Saudi Arabia (p < 0.01). No significant correlation was found between BMI and sweet taste threshold or preference and dental caries variables, respectively.

Conclusions

BMI was found to differ between countries, with a further significant difference among the groups among the Saudi Arabia schoolchildren.

Sprouts Growing Healthy Habits: Curriculum Development and Pilot Study

High rates of childhood obesity and the impact this has on children's health make it important to establish a healthy lifestyle during the early school years. This pilot study explored the impact of a newly developed healthy habits curriculum. The Sprouts: Growing Healthy Habits curriculum presents topics such as energy balance, healthy sleep habits, and food groups through short activities and interactive book-reading. A nonrandomized controlled experimental study design was used to assess impact. Fifty-seven children between 5 and 6 years of age participated from two elementary schools (36 from the intervention school, 21 from the control school). Knowledge was assessed pre- and post-intervention in five content areas (farm to table, bedtime routines, portion size, energy expenditure, sugar content of beverages) using card sorting, ranking, and sequence activities. Within- and between-school comparisons were conducted using differences between groups and mixed modeling approaches. Within the intervention school, significant increases in knowledge were observed for farm to table, sugar content of beverages, and bedtime routines. For the control school, there was a significant increase in knowledge of portion sizes. Considering between-schools, only change in knowledge of bedtime routines remained significant, with greater increases in the intervention school. Results seem promising given the short dosage of curriculum. Increases in knowledge of healthy habits in early childhood may help in promoting healthy behaviors and combatting the effects of obesity.

Dietary and physical activity patterns related to cardio-metabolic health among Malaysian adolescents: a systematic review

Background

A sedentary lifestyle and an unhealthy diet are major factors in the increasing prevalence of obesity among Malaysian adolescents. The purpose of this systematic review is to compile the evidence from observational and intervention studies among Malaysian adolescents to evaluate the associations between diet and physical activity (PA) as determinants of cardio-metabolic risk factors.

Methods

A systematic search of Medline via the PubMed, Science Direct, Cochrane Review and Web of Science databases was conducted for studies on the associations between diet and PA factors and cardio-metabolic risk factors among Malaysian adolescents aged 13–18 years that were published until 31 August 2017. The search results were independently screened and extracted by two reviewers.

Results

From over 2,410 references retrieved, 20 full texts articles were screened as potentially relevant. Seventeen (16 cross-sectional and one intervention) met the inclusion criteria for data extraction and analysis. All 17 studies were rated as poor quality and the majority had made insufficient adjustment for confounders. As regards the effect of diet and PA on cardio-metabolic health, the intakes of energy (n = 4) and macronutrients (n = 3) and meal frequency (n = 5) were the most commonly studied dietary factors, while the PA score and level were the most commonly studied PA factors. In addition, BMI and body weight were the most common cardio-metabolic health outcomes. The studies showed that obese and overweight adolescents consume significantly more energy and macronutrients. They are also more likely to skip their daily meals compared to their normal weight peers. In most studies, the direction of the PA effect on body weight was unclear. Some studies found that higher PA is associated with a lower risk of overweight and obesity. However, the associations are often small or inconsistent, with few studies controlling for confounding factors.

Conclusions

This review identified a lack of evidence and well-conducted prospective studies on the effect of diet and PA on cardio-metabolic health of Malaysian adolescents.

The extent, nature, and nutritional quality of foods advertised to children in Lebanon: the first study to use the WHO nutrient profile model for the Eastern Mediterranean Region

Objective

Exposure to food marketing may influence children’s food preferences and consumption patterns and may increase the risk of childhood obesity. The WHO Office for the Eastern Mediterranean Region (EMR) has recently released a regional nutrient profile model (WHO EMR) for the purpose of regulating the marketing of food and beverages to children. This study aimed at 1) analyzing the frequency and types of food and drink advertisements during children’s viewing time in Lebanon; 2) examining the nutritional content of the advertised food products in reference to the nutrient thresholds specified by the WHO EMR model; and 3) assessing the proportion of food advertisements that included health messages.

Design

This study consisted of a cross-sectional content analysis of food advertisements on local TV channels, during children’s viewing time.

Setting

Three local Lebanese channels with the highest viewership among 4- to 14-year-olds were selected. Recorded broadcasts (September 2016 through January 2017) were analyzed between 3 pm and 10 pm on weekdays and between 8 am and 10 pm on weekend days.

Results

Approximately 31% of advertisements were for foods or drinks. The proportion of food advertisements was the highest during children’s programs (43%) compared to general viewing (32%) and parental guidance (29%) programs. Approximately 8 out of 10 food advertisements were for products that did not meet the standards of the WHO EMR model. Of concern was the heavy advertisement of alcoholic beverages during programs for general audiences. The majority of the advertisements that comprised a health claim were for foods that did not meet the WHO EMR’s nutritional standards (79%).

Conclusions

The findings of this study, which is the first to utilize the new WHO EMR profile model, should be viewed as a foundation for the development of food marketing policies aimed at reducing children’s exposure to TV food advertisements in Lebanon, a country that harbors a high burden of childhood obesity.

Obesogenic food consumption among young children: the role of maltreatment

OBJECTIVE

To determine whether children exposed to a greater variety of acts of parent-to-child physical and psychological maltreatment will be at greater risk of consuming obesogenic foods at a higher frequency.

DESIGN

Survey research using a longitudinal panel design.

SETTING

In-home interviews with primary caregivers in twenty large US cities.ParticipantsA national sample of at-risk children and their families who participated in the Fragile Families and Child Wellbeing Study (FFCWS).

RESULTS

Child maltreatment emerged as a statistically significant (P&lt;0·01) and robust predictor of obesogenic food consumption, in both cross-sectional and longitudinal analyses. Child maltreatment also consistently emerged as one of the strongest predictors of obesogenic food consumption in these models. Ancillary analyses indicated that physical maltreatment plays a particularly important role in these associations.

CONCLUSIONS

A major implication of the present study is that child maltreatment prevention efforts should be reflected in interventions that seek to diminish unhealthy eating practices among children. Multi-professional teams can work together on obesity prevention not only via education but also by considering the interconnectedness of obesogenic food consumption and experiences of maltreatment.

A qualitative exploration of parents', youths' and food establishment managers' perceptions of beverage industry self-regulation for obesity prevention

OBJECTIVE

We aimed to explore the range of stakeholders' perceptions of the Balance Calories Initiative (BCI), under which the American Beverage Association pledged to decrease per capita US consumption of beverage energy by 20 % by 2025.

DESIGN

Semi-structured cross-sectional interviews were conducted in 2017.

SETTING

Participants were recruited from communities targeted by the BCI (Montgomery, AL; North Mississippi Delta, MS; Eastern Los Angeles, CA).ParticipantsA total of thirty-three parents and thirty-eight youths aged 10-17 years were recruited through youth-serving organizations, street intercept and snowball sampling; sixteen store/restaurant managers were recruited at businesses. Participants were asked about their awareness of the BCI. Parents and youths were asked to 'think aloud' as they viewed BCI messages (e.g. 'Balance What You Eat, Drink, and Do') and managers were asked about beverage marketing.

RESULTS

Twelve parents and twenty-four youths had seen BCI messages; only four managers were aware of the BCI. Many parents and youths showed some misunderstanding of BCI messages (e.g. that they should drink more sugar-sweetened beverages (SSB) or they needed to equalize healthy and unhealthy beverage intake). Only one manager had communicated with beverage companies about the BCI.

CONCLUSIONS

We found mixed comprehension and low awareness of BCI messages in communities targeted by the American Beverage Association for reduced SSB consumption. Industry self-regulation attempts to reduce SSB consumption may have limited effectiveness if stakeholder input is not addressed. Public health practitioners should be aware of the need to address youths' and parents' misunderstandings about SSB consumption, especially in BCI-targeted communities.
