Nutritional knowledge, nutritional status and associated factors among pregnant adolescents in the West Arsi Zone, central Ethiopia

When pregnancy occur among teenagers; there is a competition for nutrients between the still-growing adolescent mother and her fetus. Pregnant adolescents' nutrition issues are not addressed well and changes are too slow in Ethiopia. This study aimed to study, nutrition knowledge, nutritional status and associated factors among pregnant adolescents in West Arsi , central Ethiopia. We conducted a cross-sectional study of 426 pregnant adolescents between January 1 and January 25, 2023. Data were collected using kobo collect and analyzed using SPSS version 25. We performed linear regression to identify independent predictors of nutritional status and multivariable logistic regression analyses to identify nutritional knowledge. Odds ratios (ORs) with 95% confidence intervals were estimated to show the strength of the association. Magnitude of good nutrition knowledge was 23.7%, 95% CI (21.4-25.3%), and the odds of having good nutrition knowledge was 7.5 times higher among participants whose education level was above college compared with illiterate participants [(AOR = 7.5, 95% CI = (5.27-9.38)],the odds of having good nutrition knowledge was 8 times higher among adolescent who had ANC visits, [(AOR = 8, 95% CI = (3.63-13.85)], and the odds of having good nutrition knowledge was 5 times higher among adolescents who received nutrition education [(AOR = 5, 95% CI = (3.67- 13.53)]. Receiving nutrition education (β = 0.25, P = 0.002) and good nutrition knowledge (β = 0.08, P < 0.001) were positively associated with nutritional status; however, food insecurity (β = - 0.93, P < 0.001) was negatively associated with nutritional status. The nutrition knowledge of pregnant adolescents was suboptimal; educational status, ANC visits and nutrition education were associated with good nutrition knowledge, whereas food insecurity, low nutrition knowledge, and not receiving nutrition education were predictors of poor nutritional status. Nutritional education interventions, increasing utilization of ANC, and interventions for improving food security are strongly recommended.

Outcomes of a homestead food production program on nutritional knowledge, dietary diversity, food security and empowerment of rural women in Tehran province, Iran

BACKGROUND

Food and nutrition insecurity is a major health issue in developing countries. Homestead food production (HFP) programs are strategies for improving food and nutrition security of a country. Iran implemented a HFP program entitled "Nutrition Improvement of Rural and Nomadic Women" in its villages for a five-year period from 2017. The current study assessed the outcomes of this mentioned program and its determinants among rural women in Tehran province.

METHODS

The population of this cross-sectional study comprised a group covered by the program (n = 143) and a non-covered group (n = 160). The participants were selected randomly from 32 villages of five counties in Tehran province. Data was collected using five questionnaires: (1) General information, (2) Women's empowerment, (3) Nutritional knowledge, (4) Dietary diversity, and (5) Household Food Insecurity Access Scale (HFIAS). Data was analyzed using the IBM SPSS version 21 and the IBM Amos SPSS version 22 software.

RESULTS

The results of the study showed no significant improvement in the expected indicators, such as frequency of home gardening, nutritional knowledge, dietary diversity, women's empowerment, and household food insecurity status among women covered by the program (p > 0.05). The structural equation modelling (SEM) results indicated that women's empowerment from the dimension of decision-making power (r = 0.151) and nutritional knowledge (r = 0.135) were the significant positive predictors of dietary diversity (p < 0.05), while household food insecurity predicted it negatively (r=-0.138) (p < 0.05).

CONCLUSION

Because the current evaluated program has not been able to improve the expected indicators, modification of the program implementation may be needed, such as: addressing the probable barriers and challenges and strengthening the facilities in the covered villages. The current study presents a model of the dietary diversity predictors for consideration in redesigning or enhancing the program.

Level of knowledge, nutritional habits, use of stimulants, and physical activity during the COVID-19 epidemic among students of physiotherapy at Wroclaw Medical University

OBJECTIVES

The COVID-19 pandemic had a huge effect around the world. The aim of this study was to determine what eating habits, physical activity, and use of stimulants were likely among physical therapy students during the outbreak.

METHODS

The 16-65-ComPAN questionnaire for views and eating habits was used. The Fagerström Test was used to determine nicotine dependence, the International Physical Activity Questionnaire to gauge physical activity, and the Alcohol Use Disorders Identification Test to determine alcohol consumption.

RESULTS

The results indicated a relatively high percentage of alcohol consumption among this group, as well as a relationship between an unhealthy diet and years of study and smoking. A high value of unhealthy diet and the relationship between dietary knowledge, body mass index, and healthy diet index were also found. No correlation was obtained between the effect of COVID-19 on the student's life and nutritional knowledge and habits, but the percentage of students negatively affected by COVID was high (51%).

CONCLUSION

The findings presented here indicate the need to take measures to increase nutritional knowledge among physiotherapy students and to take measures to reduce the use of stimulants.

Nutritional knowledge, attitude, and practice of professional athletes in an Iranian population (a cross-sectional study)

BACKGROUND

Proper nutrition is vital in promoting community health, yet insufficient knowledge and improper dietary practices can lead to deficiencies and diseases. Professional athletes depend on optimal nutrition for their performance and recovery, but a lack of understanding can impede their potential. The nutritional status of athletes impacts their overall health and sports performance. Inadequate sports nutrition knowledge may result in suboptimal practices, reducing strength, power, endurance, and immunity. Additionally, disordered attitudes can lead to dietary imbalances and an increased risk of injury. This study, conducted in Qazvin, Iran, examined athletes' nutritional knowledge, attitudes, and practices. By addressing these factors, there is potential to enhance dietary behaviors and ultimately improve athletes' performance.

METHODS

The study employed a descriptive-analytical, cross-sectional design to investigate the nutritional knowledge, attitude, and practice (KAP) of professional athletes in Qazvin, Iran. A total of 320 purposefully selected professional athletes (68.13% male, 31.87% female) from various sports fields participated in the research. The data collection tool consisted of demographic questions and a KAP questionnaire, including 27 nutritional knowledge questions, 16 nutritional attitude questions, and 14 nutritional performance questions. The quota sampling method was used to estimate sample sizes. Data analysis was carried out by SPSS v.26 using one sample t-test, one-way ANOVA, and Pearson's correlation coefficient test.

RESULTS

The results showed that nutritional knowledge (the mean value was 79.594 ± 7.015 - the optimal knowledge level = 84) and attitude (the mean value was 23.347 ± 5.300 - the optimal attitude level = 26) for athletes are low, but their nutritional practice (the mean value was 21.788 ± 3.450 - the optimal performance level = 24) was moderate. Also, professional athletes' nutritional knowledge, attitude, and practice were lower than normal (p < 0.05). Significant positive correlations were among knowledge, attitude, and practice (p < 0.05). However, there were no significant differences in nutritional knowledge, attitude, and practice among the subjects of different age groups, genders, and sports types (p > 0.05).

CONCLUSION

This study showed that the nutritional knowledge, attitude, and practice of professional Iranian athletes in Qazvin province were low; therefore, the implementation of more theoretical and applied nutrition education, such as using knowledge assessment tools and interventions, irrespective of their age, sport's field, and gender, is compelling.

Attitudes toward the integration of nutritional assessment and counseling in the framework of physical therapy: a cross-sectional survey

BACKGROUND

As the field of physical therapy increasingly acknowledges the integral role of nutritional assessment and counseling, revisiting this subject is essential due to limited updated information regarding this topic. Furthermore, it is crucial to investigate the factors that may influence physical therapists' attitudes toward integrating nutritional assessment and counseling into their physical therapy practice. The study's primary aim was to explore the attitudes of registered physical therapists in Israel toward incorporating nutritional assessment and counseling into their clinical practice. We also explored the relation between personal and professional characteristics of physical therapists and their attitudes.

METHODS

An anonymous nationwide online self-report survey was conducted. It included three sections: personal and professional background characteristics, self-reported level of nutritional knowledge and sources of nutritional knowledge, and attitudes toward incorporating nutritional assessment and counseling into practice. Descriptive statistics were calculated for all outcome measures. The total score of the attitude statements was compared between different groups of participants. Multiple linear regression analysis was used to predict positive attitudes.

RESULTS

The study included 409 physical therapists. The attitude score was 19.78 (2.53) of 25, indicating a positive attitude. A majority (67%) reported that they did not acquire knowledge regarding nutrition during their entry-level studies or in other formal settings (63%). The three primary sources of nutritional information for the participants reported were the Internet (87.0%), registered dietitian (70.0%), and professional, scientific journals (36.0%). Prior knowledge acquired during entry-level physical therapist studies and clinical experience of ≥ 13 years significantly predicted positive attitudes (β = 0.17, β = -0.13, respectively).

CONCLUSION

Registered physical therapists held a positive attitude toward incorporating nutritional assessment and counseling into their clinical practice. Two background professional characteristics were predictors of positive attitudes. Accordingly, there is need to appropriate formal education regarding nutritional issues. Further studies are required to explore the actual integration of nutrition into the physical therapy framework.

Nutritional knowledge, dietary habits and nutritional status of adults living in urban Communities in Lagos State

Background

Malnutrition is a major threat to the world's public health. While under-nutrition and micronutrient deficiencies persist, obesity is increasing worldwide. Although malnutrition has been extensively researched among children, it has become of increasing concern among adults because of the relative increase in the prevalence of diet-related non-communicable diseases (NCDs).

Objectives

This study was conducted to determine the nutritional knowledge, dietary habits and nutritional status of adults in an urban community in Lagos State.

Methods

This was a descriptive cross-sectional study involving 320 adults selected using a multi-stage sampling technique. Data was obtained using interviewer-administered questionnaires and standard anthropometric measurements. Chi-square analysis was used to compare prevalence between categories.

Results

Only 15.9% of respondents had good nutritional knowledge. The dietary habits and estimated nutrient intake showed a deficiency of fiber, energy and most micro-nutrients with the exception of zinc, iron and vitamin A. Dietary carbohydrate, protein as well as sodium levels were elevated. BMI findings estimated the prevalence of overweight at 24.8% and obesity at 17.3%. However, there was no statistically significant association observed between nutritional knowledge and status of respondents.

Conclusion

Nutritional knowledge was poor and obesity was relatively high among participants. Improved nutrition education intervention is necessary to increase knowledge and reduce obesity among adults living in urban communities in Lagos, Nigeria.

Nutritional knowledge and practices of mothers/caregivers and its impact on the nutritional status of children 6-59 months in Sefwi Wiawso Municipality, Western-North Region, Ghana

Background

Good maternal/caregiver nutrition knowledge protects the child from events that lead to low weight-for-age z-score (WAZ) and low height-for-age z-score (HAZ). Indicators of good child nutritional status have traditionally been low in cocoa-growing areas. This paper aimed to explore the relationship between maternal nutrition knowledge and practices and its effect on the nutritional status of children 6-59 months in the Sefwi Wiawso municipality; a predominant cocoa-growing area in Ghana.

Methodology

A cross-sectional study design was used to assess nutrition knowledge, nutritional practices of mothers and dietary adequacy and nutritional status of their children using 24-hour dietary recall and anthropometric measures.

Results

A total of 226 caregiver-child pairs were recruited for the study. The level of nutritional knowledge was average (61.5%) among caregivers/mothers. Most caregivers (92.3%) initiated breastfeeding within 1 hour of giving birth. A total of 66% of mothers practiced exclusive breastfeeding. Complementary feeding was initiated at 6 months in 83.6% of the cases. The prevalence of underweight, wasting, and stunting were 8.29%, 10.23%, and 16.74% respectively. There was no significant association between mother/caregiver's nutrition knowledge and child malnutrition status although the risk of wasting reduced with increasing nutritional knowledge of caregivers (p = 0.118).

Conclusion

There was no association between maternal nutrition knowledge and the nutritional status of children even though wasting showed a pattern of decrease with increasing nutritional knowledge. The prevalence of malnutrition in children in the study was comparatively lower than the national average. Underweight was statistically significantly higher in children whose mothers/caregivers were farmers hence appropriate nutrition education with a focus on infant and young child feeding practices should be promoted during antennal care and child welfare clinic services within these communities. Family planning services targeted particularly at teenage girls should be instituted to prevent teenage pregnancies as malnutrition is more likely to occur in children born to teenage mothers.

Minimum dietary diversity and associated factors among lactating mothers in Haryana, India: a community based cross-sectional study

INTRODUCTION

Food adequacy and dietary quality in the lactation period are fundamental for maternal and child health. Lactating mothers are vulnerable to malnutrition because of increased physiological demand, monotonous diet, lactogenesis process, and increased nutrient requirements. The micronutrient adequacy especially among women is not ensured in Indian diet. The dual course of gender bias and poverty, along with lack of knowledge about diet quality are significant impediments in maintaining minimum dietary diversity among Indian women. The study aimed to assess the prevalence of minimum dietary diversity and associated factors among lactating women.

METHODOLOGY

A community-based cross-sectional study was conducted among 1236 lactating women through a multistage sampling procedure in Haryana state, India. Data were collected in Computer-assisted personal interviewing (CAPI) using a pretested structured interview schedule. Minimum Dietary Diversity for Women by Food and Agriculture Organization (FAO) was used to calculate the minimum dietary diversity.

RESULTS

The mean dietary diversity score among lactating women from the ten food groups was 6.35 ± 2.57 and the prevalence of minimum dietary diversity was 77.1%. The complete model revealed that both individual and household factors can explain the variation in dietary diversity intake. Furthermore, the result of model 2 explained that women aged 31 to 35 years (AOR 5.92,95% (1.87-18.77), graduation and above qualified women (AOR 1.98, 95% (0.96-4.09) and lactating women with high knowledge on nutrition (AOR 2.00, 95% (1.34-4.57) were the significant factors promoting minimum dietary diversity.

CONCLUSION

Three-fourths of the lactating women reached adequate minimum dietary diversity. Younger age, low educational level, and poor nutritional knowledge were significant constraints to achieving minimum dietary diversity. Further improvement in the minimum dietary diversity among lactating women is very much required. It is also advised that exiting platforms dispersing awareness on nutrition should be supported and strengthened.

Evaluating the impacts of school garden-based programmes on diet and nutrition-related knowledge, attitudes and practices among the school children: a systematic review

BACKGROUND

Previous evidence suggests that school garden-based programmes (SGBP) may be a promising yet cost-effective intervention to improve children's knowledge, attitudes and practices (KAP) on healthy eating. This review aimed to summarise and evaluate the evidence available on the impacts of SGBP in addressing diet and nutrition-related KAP among school-aged children.

METHODS

Five databases including PubMed, Embase, Cochrane, Web of Science and Scopus were searched until February 2021. Randomised, non-randomised controlled and pre-post intervention studies investigating the impacts of SGBP on at least one of the outcomes of interest including diet and nutrition-related knowledge, attitudes towards fruits and vegetables (F&V), food diversity and dietary practice among school-aged children were included. Study selection and data extraction were performed by one reviewer and checked for accuracy by the other two reviewers in accordance with PRISMA guideline. Quality appraisal for studies included was assessed using American Dietetic Association Quality Criteria Checklist.

RESULTS

A total of 10,836 records were identified, and 35 studies that met the inclusion and exclusion criteria were included. This includes 25,726 students from 341 schools and 8 nurseries from 12 countries. Intervention duration ranged from 6 weeks to 4 years with 18 studies involving a varied degree of parental participation. SGBP, which majorly includes school gardening activities, cooking lessons and nutrition education, demonstrated beneficial effects on children's nutritional knowledge, their attitudes and acceptability towards fruits and vegetables and children's dietary practices including the actual F&V consumption and dietary diversity. However, the impacts of SGBP on such outcomes were highly influenced by various social and environmental factors including the activities/components and duration of the intervention, parental involvement, sample size, and the age of children when interventions were first introduced.

CONCLUSION

These findings suggest that SGBP may be effective in promoting children's nutritional knowledge, attitudes and acceptability towards vegetables, however, the impacts may vary by the type, the extent, and the length of the programmes, and other factors such as parent involvement. Future SGBP is suggested to implement using a combined multidisciplinary approach targeting the children, parents, and community to effectively promote healthy eating among the children and prevent childhood obesity.

Identifying dietary patterns in Irish schoolchildren and their association with nutritional knowledge and markers of health before and after intervention

The aim of the study was to identify dietary patterns (DP) and examine differences in anthropometric measures, blood pressure (BP), cardiorespiratory fitness and nutritional knowledge of 6- and 10-year-old children at baseline and following a nutrition and physical activity intervention, with respect to DP and treatment group. This is a longitudinal study. Food diary, nutritional knowledge questionnaire and 550-m walk/run test measured dietary intake, nutritional knowledge and cardiorespiratory fitness, respectively. BP, weight, height and waist circumference were also measured and BMI and waist-to-height ratio (WHtR) were derived. All measurements were performed at baseline and following intervention. Two primary schools (one intervention, one control) in Cork, Ireland, were selected. Participants were 6- (n 39, age 5·9 (sd 0·6) years) and 10- (n 49, age 9·8 (sd 0·5) years)-year-olds. Two DP were identified, using k-means cluster analysis, for both 6- (unhealthy and nutrient-dense) and 10-year-olds (processed and Western diet) at baseline. DP derived post-intervention were (1) plant-based and (2) processed foods for 6-year-olds and (1) nutrient-dense and (2) unhealthy for 10-year-olds. There was no statistically significant difference in DP for 6- and 10-year-olds at baseline and post-intervention (P > 0·05). Following the intervention, a multivariate ANOVA showed there were no statistically significant differences in nutritional knowledge, BMI, WHtR, cardiorespiratory fitness and BP based on DP and intervention/control group for both age groups (P > 0·05). Three out of four dietary patterns identified for 6- and 10-year-olds were unfavourable. While no statistically significant evidence of intervention impact was found on DP, a positive trend was emerging among 10-year-olds.

Nutritional status and associated factors among people living with HIV/AIDS in Ghana: cross-sectional study of highly active antiretroviral therapy clients

Background

Nutrition among people living with HIV/AIDS (PLWHA) is essential in their care and management as it has implication for their immune function. We examined the nutritional status and associated factors among HIV positive clients accessing Highly Active Anti-Retroviral Therapy (HAART) at a public hospital in Ghana.

Methods

This was a descriptive cross-sectional study of 152 clients. Anthropometric measurements for weight and height were carried out in 2019. Data were analysed using SPSS 22.0. Descriptive and analytical statistics comprising frequency, percentage, and binary logistic regression were adopted in presenting the results.

Results

Seventy-nine percent and 74% of the clients had good nutrition knowledge and attitude, respectively. Also, 42% were malnourished (underweight = 13.8%, and overweight = 28.3%). Clients with primary (AOR = 0.36, 95% CI = 0.07–1.84), JSS/JHS (AOR = 0.26, 95% CI = 0.08–0.84), SSS/SHS (AOR = 0.22, 95% CI = 0.05–1.02) and tertiary (AOR = 0.26, 95% CI = 0.08–0.88) were less likely to be malnourished compared with those with no formal education. Those with good nutrition-related knowledge were 56% (AOR = 0.44, 95% CI = 0.18–1.09) less likely to be malnourished than those with poor knowledge; this was however, not statistically significant.

Conclusion

We found a high prevalence of malnutrition among the clients which militates against progress towards achieving the Sustainable Development Goal targets 3.3 and 3.4 of stopping AIDS epidemic and preventing premature deaths from malnutrition. Our findings justify the need for the implementation of innovative interventions by stakeholders in Ghana’s health industry to improve the nutritional status of people living with the disease.

Knowledge and food practices questionnaire: construction and validation

OBJECTIVES

To develop and validate an instrument about nutritional knowledge and feeding practices to be used in children aged 7-11 years, based on the latest Brazilian Food Guide.

METHODS

Review on the subject; instrument creation; content validity with two groups of judges: first, nutritionists and, after adjustments, a multidisciplinary group (content validity index [CVI]); FACE validity; reproducibility analysis (intraclass correlation coefficient [ICC], level of agreement, and kappa [k]); internal consistency analysis (Cronbach's alpha[α]) and construct validity (Kaiser-Meyer-Olkin and exploratory factorial analysis). The sample was calculated, considering at least ten subjects for each question of the questionnaire.

RESULTS

There was a final sample of 453 children (53.6% girls), with a mean age of 9.45 years (SD = 1.44). The content validity showed a CVI ≥ 0.80 for relevance in 62.3% of the items for nutritionists' group and 100% of the items for the multidisciplinary group, clarity (49.4%, 91.8%), and pertinence (58.8%, 98.4%), respectively. The test-retest showed a level of agreement of 84.3% and k = 0.740 for the Knowledge dimension and ICC = 0.754 for the Food Practices dimension. The internal consistency showed α = 0.589 for the Knowledge dimension and α = 0.618 for the Food Practices dimension. For the construct validity, Kaiser-Meyer-Olkin was 0.724 and exploratory factorial analysis showed a variance of 47.01 with varimax rotation and defined five factors for the Practices Dimension.

CONCLUSION

The Food Knowledge and Practices Questionnaire (Questionário de Conhecimento e Práticas Alimentares [QCPA]) instrument showed validity and reliability to assess nutritional knowledge and food practices in children aged 7-11 years.

Effectiveness of a nutrition education and intervention programme on nutrition knowledge and dietary practice among Princess Nourah Bint Abdulrahman University's population

OBJECTIVE

The study sought to assess the influence of nutrition education and intervention programmes on nutrition knowledge and dietary practice among both students and staff (including faculty) of Princess Nourah Bint Abdulrahman University in Saudi Arabia.

DESIGN

A pretest-posttest, non-randomised experimental study design was implemented at Princess Nourah Bint Abdulrahman University in Riyadh City between September 2019 and February 2020.

SETTING

Princess Nourah Bint Abdulrahman University is the largest women's university in the world and has eighteen colleges and institutions and around ninety academic programmes.

PARTICIPANTS

The survey was completed by 1824 participants (1350 students and 474 staff/faculty) before the intervention and by a different cohort of 1731 participants (1317 students and 414 staff/faculty) after the intervention. In total, an independent sample of 3555 staff and students participated. Participants were asked about dietary knowledge and practices. Dietary knowledge entailed food variety and nutrients, fast food and its poor nutritional value, and the influence of cooking style on the nutritional quality of food. Dietary practices involved eating breakfast; consuming salt/sugar, eating high-salt food; eating pre-packaged food and consumption of vegetables, fruits, supplements, water and caffeine.

RESULTS

The majority of the sample consisted of students (75·1 %) and had not been diagnosed with any disease (73·7 %). The result of the current study showed that nutrition knowledge improved after completion of the nutrition programme.

CONCLUSIONS

The nutrition awareness programme improved students' nutritional knowledge; however, there was no significant effect on their dietary practices. Future nutrition awareness programmes should separate activities for students and staff, focusing on one target population at a time.

Diet quality scores in relation to fatness and nutritional knowledge in women with polycystic ovary syndrome: case-control study

OBJECTIVE

The purpose of the study was to analyse the dietary habits identified by diet quality scores (DQS) in the scope of body fatness (BF) and nutritional knowledge (NK) of polycystic ovary syndrome (PCOS) women.

DESIGN

Case-control study. The DQS were accessed by Dietary Habits, and Nutrition Beliefs Questionnaire (KomPAN, The Committee of Human Nutrition, Polish Academy of Science) included food frequency consumption of thirty-three food items and was formulated by six diet indexes: Pro-Healthy-Diet-Index (pHDI-10), Non-Healthy-Diet-Index (nHDI-14), High-Glycemic-Diet-Index-7 (hGIDI-7), Low-Glycemic-Diet-Index-4 (lGIDI-4), High-Sugar-Diet-Index-4 (hSDI-4) and High-Saturated-Fats-Diet-Index-8 (hSFDI-8). The BF was analysed by air displacement plethysmography (BodPod, Life Measurement Inc.). NK was assessed by using the twenty-five 'true or false' statements included in the KomPAN questionnaire.

SETTING

Poland, Clinical Hospital, Department of Endocrinology, Metabolism, and Internal Diseases.

PARTICIPANTS

The study group included 122 PCOS women and 116 age- and socio-economic status-matched healthy controls (CON) aged 17-44 years.

RESULTS

Higher BF and lower NK in PCOS women v. controls were observed. PCOS women had a lower pHDI-10 and LGIDI-4 than CON. There was no relation between NK and DQS in PCOS women. The higher NK in the CON group was associated with increased intensity of pHDI-10 and lower frequency of hSFDI-8 levels.

CONCLUSIONS

Pro-healthy DQS and NK of PCOS women in this study were lower than CON. Professional dietary education might improve dietary behaviours and understanding of the necessity of dietary habits modification in this group. A multidisciplinary approach is needed in the treatment of PCOS women.

A comparative study on nutritional knowledge and dietary behavior between Korean and Chinese postpartum women

BACKGROUND/OBJECTIVES

Proper nutrition intake during pregnancy and lactation is very important to both mothers and babies. Pregnant women should maintain proper nutritional status to restore decreased physical strength due to pregnancy and childbirth and produce breastmilk for the growth and development of the baby. Recently, the number of Chinese people living in Korea has increased as the exchange between Korea and China becomes active. It is important to provide proper nutrition education for pregnant women of both countries considering cultural differences.

SUBJECTS/METHODS

The subjects of this study were postpartum women in Gyeonggi, South Korea and Jinhua, China. The subjects were 20-45 years old less than six months after childbirth. A survey, using self-administered questionnaires, was conducted from October 2018 to January 2019. For data analysis, 221 Korean postpartum women (KPW) and 221 Chinese postpartum women (CPW) questionnaires were used.

RESULTS

KPW had significantly higher nutritional knowledge score and dietary attitude score than CPW (P < 0.001). However, overall score for dietary habits was significantly higher in CPW compared to KPW (P < 0.001). In KPW, nutritional knowledge (P < 0.01) and dietary attitude (P < 0.001) had significantly positive correlations with dietary habits. The proportions of KPW and CPW who answered that they had experience of nutrition education were 28.5% and 80.1% (P < 0.001). The score for dietary habits was lower as the hours for watching TV and using mobile phone became longer in postpartum women of both countries, with significant differences in KPW (P < 0.001) and CPW (P < 0.05). In KPW, the score for dietary habits in postpartum women with exercise experience was significantly higher than that in postpartum women without exercise experience (P < 0.001).

CONCLUSIONS

More pregnancy-related nutrition education should be provided and various and effective nutrition education programs, which not only transfer information but can be practiced in the actual life, should be developed.

Evaluation of a questionnaire to assess nutritional knowledge, attitudes and practices in a Thai population

Background

The rapid increase in non-communicable chronic diseases in people of working age has had a major effect on health care utilization, productivity and economy. Lifestyle and diet are recognized as being major risk determinants involved. Disease prevention strategies need to be based on people’s understanding of nutritional knowledge, attitudes and practice. This study evaluates the validity of a new nutritional knowledge and practice questionnaire specifically developed for assessing individuals of working age in a Thai population.

Methods

The questionnaire was constructed and based on previous relevant literature and its content validity was scrutinized by an expert panel. An exploratory factor analysis (EFA) was performed to reduce the number of questions included. Subsequently, data from a cross-sectional study of 1,032 participants were used to evaluate the reliability and validity of this questionnaire. The validity of the questionnaire constructed for assessing knowledge and attitude was evaluated using Confirmatory Factor Analysis (CFA). For the practice component, set criteria were applied to determine the final variables used.

Results

CFA of the nutritional knowledge component suggested that all the variables in the model fitted with the data (χ² = 80.17, df = 66, p > 0.05, CFI = 0.99, RMSEA = 0.01, SRMR = 0.02). The CFA final model for the nutritional knowledge included three factors (food recommendation, nutrients related to diseases, and healthy diet) with a total of 14 questions. For nutrition attitude, CFA also revealed a good fit (χ² = 178.14, df = 93, p < 0.001, CFI = 0.99, RMSEA = 0.03, SRMR = 0.03). The final CFA model for nutritional attitude included three factors (food choice, healthy diet and food recommendation) with a total of 16 questions. For practice items, the number of questions was reduced from 76 to 60.

Conclusions

Questionnaire development should use a logical, systematic and structured approach. Results from our evaluation process demonstrates the construction validity of the nutritional knowledge and practice questionnaire developed. This questionnaire can be further modified for use in other countries within the region.

Nutritional knowledge, dietary practice and associated factors among adults on antiretroviral therapy in Felege Hiwot referral hospital, Northwest Ethiopia

Background

Nutritional support is identified as one of the most critical and immediate needs for people living with human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS). Adequate nutrition is vital to optimize response to medical treatment, manage opportunistic infections, maintain the immune system, and support optimal quality of life for people living with HIV/AIDS (PLWHA). Evidence has shown that the progression of the disease could be slowed with good nutrition. Nutrition interventions increase compliance with treatment regimens and optimize the benefits of antiretroviral drugs. The nutritional knowledge, dietary practice and associated factors among adults on antiretroviral therapy are not well understood generally in Ethiopia and particularly in Bahir Dar City. Therefore, the aim of this study was to assess the nutritional knowledge, dietary practice and associated factors among adult PLWHA on anti-retroviral therapy (ART) in Felege Hiwot Referral Hospital.

Methods

Institution based cross-sectional study was conducted from April 13 to May 18, 2017 in Felege Hiwot Referral Hospital. Systematic random sampling technique was used to select 539 adults on highly active antiretroviral treatment (HAART). Data were collected using a semi-structured and pretested questionnaire. Bivariate and multivariate logistic regression analyses were carried out to identify factors associated with nutritional knowledge and dietary practice.

Results

This study shows that 25.8, 52.5 and 21.7% of respondents had poor, average and good nutritional knowledge scores respectively. Ever heard about good nutrition and received dietary counselling were significant factors for nutritional knowledge. This study also reveals that 3.2, 66.4 and 30.4% of respondents had poor, average and good dietary practice scores respectively. Presence of gastrointestinal symptom, ever heard about good nutrition and good nutritional knowledge were significant factors for dietary practice.

Conclusions

This study found that the magnitude of good nutritional knowledge and good dietary practice were 21.7 and 30.4%. Nutrition education and counseling should be given by health care workers for patients on ART to improve their nutritional knowledge. The media should also strengthen its role in disseminating nutrition information. The health professionals should routinely diagnose and treat gastrointestinal symptoms to maintain patients' appetite for food their by increasing dietary intake.

Level of nutrition knowledge and its association with fat consumption among college students

BACKGROUND

Intake of saturated fat, trans fat, and cholesterol has been associated with increased risk of coronary heart disease. The aim of this study was to explore whether increased nutrition knowledge is associated with a reduction in the consumption of unhealthy fats in a sample of university students.

METHODS

A sample of 231 students, with a mean age of 20 years, was recruited from university campus during spring 2012. Students completed a validated questionnaire related to students' demographic, nutrition knowledge, and daily fat consumption. Weight, height, and waist circumference were measured. Data were analyzed using one-way ANOVA, chi-square, and student's t-test.

RESULTS

Results indicate that female students have greater nutrition knowledge than male students (the mean nutrition score for women was 5 points higher than that of men (P = 0.01)). Nutrition knowledge was negatively correlated with fat and cholesterol intake. Students who consumed more than 35 % calories from fat or >300 mg of cholesterol daily had lower mean nutrition scores than those students with lower fat or cholesterol intake (8 points lower and 7.9 points lower, respectively). Using linear regression for nutrition scores on estimated saturated fat intake and cholesterol intake (controlling for gender, height, weight, age, and dieting), nutrition scores were negatively associated with saturated fat intake (-0.15, P <0.0001) and cholesterol intake (-1.38, P <0.0001).

CONCLUSION

Students with greater nutritional knowledge consumed less unhealthy fats and cholesterol. This finding magnifies the role of nutrition education as a potential tool in health campaigns to promote healthy eating patterns among college students. Results of this pilot study can inform the design of future nutrition education intervention studies to assess the efficacy of nutrition knowledge on pattern of fat consumption among college students.

Health and dietary traits of organic food consumers: results from the NutriNet-Santé study

The dietary and health traits of organic food (OF) consumers have not been comprehensively described. The aim of this study was to identify factors associated with OF consumption. Data were collected from 54 283 participants from the NutriNet-Santé cohort using self-administered web-based questionnaires. Occasional organic food consumers and regular organic food consumers (ROFC) were compared with non-organic food consumers (NOFC) using logistical regression providing an OR and 95 % CI. Adherence to the French food-based guidelines and interactions between nutritional knowledge and OF consumption in adherence to dietary guidelines were investigated. Medical history was also assessed in relation to OF consumption. Compared with NOFC, ROFC were more likely to be vegetarian (OR 9·93; 95 % CI 7·42, 13·29 in women; OR 13·07; CI 7·00, 24·41 in men) and were less likely to be aware of nutritional guidelines regarding meat consumption (OR 0·37; CI 0·34, 0·40 in women; OR 0·41; CI 0·36, 0·47 in men). Compared with NOFC, ROFC had a lower risk of type II diabetes, hypertension and CVD; however, this effect was only significant for men. In contrast, organic consumers were more likely to report food allergies. Consuming OF appeared to affect the relationship between nutritional knowledge and adequate intake of meat/poultry/seafood/eggs and starchy food among both sexes. Our study provides new insights into the diet- and health-related behaviours of OF consumers in a large sample of participants residing in France. This should be taken into account in future studies investigating relationships between health and OF consumption.

A comparative study of nutritional status and foodstuffs in adolescent girls in iran

BACKGROUND

The prevalence of obesity and overweight in children and adolescents is increasing world-wide. Obesity in children and adolescents is a major risk factor for diabetes, heart diseases, hypertension, and cancer in adulthood.

AIM

The aim of the study was to compare the nutritional status and food-stuffs among high-school girls in Arak, Iran, in matter of body mass index (BMI) and associated factors.

SUBJECTS AND METHODS

A cross-sectional survey of a representative sample of 278 adolescents was conducted in six randomly chosen high-schools. Height and weight of students were collected using standard methods and the BMI calculated and BMI percentiles of these girls are compared with the Center of Disease Control and Prevention (CDC) reference data. The 5(th), 8(th), and 95(th) percentiles of the CDC were adopted as cut-off points for underweight, overweight and obese girls, respectively. Data were analyzed using SPSS by analysis of variance and Chi-square tests.

RESULTS

On the basis of CDC, the overall prevalence rates of underweight, overweight, and obesity were estimated 10.1% (28/278), 12.9% (36/278), and 1.4% (4/278), respectively. There was no significant difference between nutritional knowledge scores and the rate of physical activities in various groups. The mean age at menarche was significantly higher among the obese girls (P = 0.02). Consumption of ice-cream and chocolate was significantly higher in the obese girls group (P = 0.03).

CONCLUSION

According to the present study, the prevalence of overweight and obesity in high-school girls of Arak is lower than that of many other parts of Iran and some neighboring countries, which are at the high-risk of overweight and obesity. This study warrants the necessity of paying attention to promote healthy life-style and weight control. The earlier age of menarche is alarming.

Fruit and vegetable intake among older adults: a scoping review

Older adults are the fastest growing segment of the world population. Older adults are also at heightened risk of chronic conditions (such as diabetes, heart disease, and cancer) and specific geriatric conditions (such as cognitive impairment, frailty, and falls). Research studies have examined the relationship between fruit and vegetable intake and subsequent health outcomes and the correlates of fruit and vegetable intake in the U.S. population. However, relatively few studies have specifically examined health impacts and correlates of fruit and vegetable intake among older adults, who have unique biophysical and socioeconomic circumstances. Evidence is reviewed to (1) describe findings related to consumption and chronic, geriatric, and other health outcomes among older adults and (2) describe patterns in fruit and vegetable consumption among older adults and how these patterns vary within and among populations. This review addresses specific barriers faced by older adults in obtaining and consuming fruits and vegetables in community settings. Recommendations for practice and policy are discussed.

Effect of Mothers Nutritional Knowledge and Attitudes on Omani Children's Dietary Intake

OBJECTIVES

The study investigates the dietary intakes of Omani preschoolers and associations with both socio-demographic characteristics and the mother's nutritional knowledge and attitudes.

METHODS

A sample of 154 parents of preschoolers completed a questionnaire including socio-demographic characteristics, a food-frequency questionnaire to assess children's food intake, nutritional knowledge and attitudes towards healthy eating.

RESULTS

The results showed a lower dietary adequacy of children's food intake in mothers with low educational levels, high-ranked occupation, and lower levels of both nutritional knowledge and food related health attitudes. The highest food intake and healthy eating attitude scores were found in children of mothers with high education level and mother without a job. The association of the dietary adequacy with socio-demographic background can help the Omani healthcare decision makers to develop better-tailored nutrition interventions which are more suitable for the Omani community.

CONCLUSION

The results from this study of mothers' nutritional knowledge and attitudes support the inclusion of knowledge and attitudes in dietary interventions.
