Physical activity in adults with and without diabetes: from the 'high-risk' approach to the 'population-based' approach of prevention

Factors associated with physical inactivity among Palestinians with type 2 diabetes mellitus treated in resource-limited settings

This study determined the prevalence and the associated factors with meeting the recommended amount of physical activity among type 2 diabetes mellitus (T2DM) patients receiving care in resource-limited settings of the West Bank of Palestine. Physical activity was assessed using the World Health Organization's Global Physical Activity Questionnaire. Associations were examined using multivariate logistic regression. Of the 302 patients included, 117 (38.7%) met the recommended amount of physical activity. Being younger than 58 years [aOR = 2.1 (95% CI 1.0-4.3], were employed [aOR = 2.3 (95% CI 1.1-4.9)], had high income [aOR = 3.9 (95% CI 1.3-11.9)], had thought that physical activity was crucial for T2DM patients [aOR = 32.7 (95% CI 3.9-275.5)], did not have comorbidities [aOR = 2.2 (95% CI 1.1-4.4)], had normal weight [aOR = 2.8 (95% CI 1.3-6.0)], and those who were overweight [aOR = 2.6 (95% CI 1.1-6.0)] were more likely to meet the recommended amount of physical activity compared to the patients who were 58 years or older, had low income, did not think that physical activity was crucial for T2DM patients, had comorbidities, and were obese, respectively. There is a need to increase physical activity among T2DM patients in resource limited settings.

Political Economy of Non-Communicable Disease (NCD) prevention and control in Lebanon: identifying challenges and opportunities for policy change and care provision reforms

INTRODUCTION

Lebanon is a middle-income country facing substantial fragility features. Its health profile shows a high burden of NCD morbidity and mortality. This paper intends to analyse the political economy of NCD prevention and control in Lebanon.

METHODS

This study adopted a literature-based case study research design using a problem-driven political economy analysis framework. A total of 94 peer-reviewed articles and documents from the grey literature published before June 2019 were retrieved and analysed.

RESULTS

Lebanon's political instability and fragile governance negatively affect its capacity to adapt a Health-in-All-Policies approach to NCD prevention and enable the blocking of NCD prevention policies by opposed stakeholders. Recent economic crises limit the fiscal capacity to address health financing issues and resulting health inequities. NCD care provision is twisted by powerful stakeholders towards a hospital-centred model with a powerful private sector. Stakeholders like the MOPH, UN agencies, and NGOs have been pushing towards changing the existing care model towards a primary care model. An incremental reform has been adopted to strengthen a network of primary care centres, support them with health technologies and improve the quality of primary care services. Nevertheless, outpatient services that are covered by other public funds remain specialist-led without much institutional regulation.

CONCLUSION

Our study revealed a locked equilibrium in NCD prevention policymaking in Lebanon, but with an incremental progress in service delivery reforms towards a primary care model. Advocacy and close monitoring by policy entrepreneurs (such as civil society) could initiate and sustain the implementation of policy change and care model reforms.

Trends in health behaviors of US adults with and without Diabetes: 2007-2018

AIMS

Understanding health behaviors of people with diabetes can inform strategies to reduce diabetes-related burdens.

METHODS

We used serial cross-sectional National Health and Nutrition Examination Surveys over 2007-2018 to characterize self-reported health behaviors among non-pregnant adults, with and without self-reported diabetes. We estimated weighted proportions meeting recommended health behaviors overall and by sociodemographic and glycemic levels.

RESULTS

During 2007-2010, proportions of adults with diabetes meeting recommendations were: 61.9 % for added sugar consumption (<10 % of total calories), 17.2 % for physical activity, 68.2 % for weight management, 14.4 % avoided alcohol, 57.5 % avoided tobacco, 34.1 % got adequate sleep, and 97.5 % saw a healthcare provider (compared with 19.2 %, 33.6 %, 68.8 %, 8.5 %, 44.2 %, 33.0 %, and 82.6 % respectively, among those without diabetes). During 2015-2018, adjusted analyses showed more adults with diabetes met sleep (+16.7 percentage-points[pp]; 95 % CI: 10.6,22.8) and physical activity goals (+8.3 pp; 95 % CI: 3.8,12.8), and fewer met added sugar recommendations (-8.8 pp; 95 % CI -14.7, -2.9). Meeting added sugar, physical activity, and weight management varied by age, education, and glycemic level, but not race and ethnicity.

CONCLUSIONS

During 2007-2018, there was some improvement in health behaviors. Improving self-management may require targeted interventions for different segments, like age groups or glycemic levels, among those with diabetes.

Factors Associated With Changes in Objectively Measured Moderate to Vigorous Physical Activity in Patients After Percutaneous Coronary Intervention: A Prospective Cohort Study

BACKGROUND

This study aimed to clarify factors affecting changes in moderate to vigorous physical activity (MVPA) in patients 1 to 3 months after undergoing percutaneous coronary intervention (PCI).

METHODS

In this prospective cohort study, we enrolled patients aged <75 years who underwent PCI. MVPA was objectively measured using an accelerometer at 1 and 3 months after hospital discharge. Factors associated with increased MVPA (≥150 min/wk at 3 mo) were analyzed in participants with MVPA < 150 minutes per week at 1 month. Univariate and multivariate logistic regression analyses were performed to explore variables potentially associated with increasing MVPA, using MVPA ≥ 150 minutes per week at 3 months as the dependent variable. Factors associated with decreased MVPA (<150 min/wk at 3 mo) were also analyzed in participants with MVPA ≥ 150 minutes per week at 1 month. Logistic regression analysis was performed to explore factors of declining MVPA, using MVPA < 150 minutes per week at 3 months as the dependent variable.

RESULTS

We analyzed 577 patients (median age 64 y, 13.5% female, and 20.6% acute coronary syndrome). Increased MVPA was significantly associated with participation in outpatient cardiac rehabilitation (odds ratio 3.67; 95% confidence interval, 1.22-11.0), left main trunk stenosis (13.0; 2.49-68.2), diabetes mellitus (0.42; 0.22-0.81), and hemoglobin (1.47, per 1 SD; 1.09-1.97). Decreased MVPA was significantly associated with depression (0.31; 0.14-0.74) and Self-Efficacy for Walking (0.92, per 1 point; 0.86-0.98).

CONCLUSIONS

Identifying patient factors associated with changes in MVPA may provide insight into behavioral changes and help with individualized PA promotion.

Prevalence and associated factors of physical inactivity among adult diabetes mellitus patients in Felege Hiwot Referral Hospital, Bahir Dar, Northwest Ethiopia

Physical inactivity has been viewed as an emerging public health problem in developing countries including Ethiopia. Diabetes mellitus (DM) is a group metabolic disorder characterized by chronic hyperglycemia resulting from defects in insulin secretion, function, or both. Its prevalence increases with changing lifestyles including physical inactivity across the globe. However, there is limited research, and not yet received attention in Ethiopia. This study aimed to assess the prevalence and associated factors of physical inactivity among adult diabetic patients in Felege Hiwot Referral Hospital, Bahir Dar, Northwest Ethiopia. An institutional-based cross-sectional study design was conducted among 308 participants from February to June 2018 at Felege Hiwot Referral Hospital. A face-to-face interview was conducted using a structured questionnaire by trained data collectors. Participants were selected through a systematic random sampling technique. Physical inactivity was assessed by the international physical activity questionnaire (IPAQ). Collected data were entered in Epi info version 7 and transferred to SPSS version 20 for analysis. A summary of descriptive statistics and multiple binary logistic regression analyses were computed to identify associated factors of physical inactivity among adult diabetic patients. P < 0.05 with 95% CI was considered statistically significant. The overall prevalence of physical inactivity among diabetic patients was 30.5% ( 95% CI: 22.8-33.5%). Gender (AOR = 1.5, 95% CI: 1.1, 3.62), Old age (AOR = 18.17, 95% CI: 22.7, 61.9) Residence (AOR = 4.24, 95% CI: 1,12,16.028), Low self-efficacy (AOR = 20.59, 95% CI: 10.598, 41.608), Poor attitude (AOR = 2.75, 95%CI: 1.44,5.28), and Lack of social support (AOR = 4.22, 95% CI: 1.28,4.07) were found significantly predictor factors of physical inactivity. The prevalence of physical inactivity in this study was high. Being female, old age, dwelling in an urban, having low efficacy, poor attitude, and lack of social support was greater risk factors for being physically inactive. Diabetic education should focus on engagement in physical activity by overcoming barriers to performing physical activity. Government and health professionals should emphasize that evidence-based physical activity important to change their attitudes and require reaching a consensus on social support by their families.

Risk Factors for Coronary Heart Disease Among Lebanese Women: A Case–Control Study

Purpose

Women are increasingly concerned by coronary heart disease (CHD), with peculiarities of their own, particularly concerning risk factors. The aim of the study was to assess the risk factors for CHD in Lebanese women over forty.

Patients and Methods

A case–control study was carried out in 6 hospitals in Beirut and Mount-Lebanon, from December 2018 to December 2019 including 1500 patients (1200 controls and 300 cases). Women were stratified into pre- and post-menopausal groups. Personal and medical data were collected from hospital records and during an interview where validated questionnaires were used. Binary logistic regressions were performed to investigate potential predictors of CHD in the 2 groups.

Results

In post-menopausal women, dyslipidemia (adjusted odds ratio [aOR], 3.018; 95% confidence interval, 2.102–4.332), hypertension (aOR: 2.449, [1.386–4.327]), a family history of CHD (aOR: 2.724, [1.949–3.808]), cigarette smoking (aOR: 2.317, [1.574–3.410]) and common non-rheumatic joint pain (aOR: 1.457, [1.053–2.016]) were strongly associated with CHD. Conversely, living in Mount Lebanon seemed protective, compared to Beirut (aOR: 0.589, [0.406–0.854]), as well as having a moderate monthly income (aOR: 0.450, [0.220–0.923]), adhering to a Mediterranean diet (aOR: 0.965, [0.936–0.994]), and practicing physical activity [PA] (aOR: 0.396, [0.206–0.759] and 0.725, [0.529–0.992], respectively for high and moderate vs low PA). In pre-menopausal women, dyslipidemia (aOR: 6.938, [1.835–26.224]), hypertension (aOR: 6.195, [1.318–29.119]), family histories of dyslipidemia (aOR: 6.143, [1.560–24.191]) and CHD (aOR: 4.739, [1.336–16.805]) reached statistical significance.

Conclusion

The identification of factors associated with CHD in women, some of which are frequent and trivialized in post-menopause, underlines the need to put in place specific and dedicated CHD prevention strategies in women.

The Effectiveness of Mobile Phone Messaging-Based Interventions to Promote Physical Activity in Type 2 Diabetes Mellitus: Systematic Review and Meta-analysis

Background

The prevalence of type 2 diabetes mellitus (T2DM) is increasing worldwide. Physical activity (PA) is an important aspect of self-care and first line management for T2DM. SMS text messaging can be used to support self-management in people with T2DM, but the effectiveness of mobile text message–based interventions in increasing PA is still unclear.

Objective

This study aims to assess the effectiveness of mobile phone messaging on PA in people with T2DM by summarizing and pooling the findings of previous literature.

Methods

A systematic review was conducted to accomplish this objective. Search sources included 5 bibliographic databases (MEDLINE, Cochrane Library, CINAHL, Web of Science, and Embase), the search engine Google Scholar (Google Inc), and backward and forward reference list checking of the included studies and relevant reviews. A total of 2 reviewers (MA and AA) independently carried out the study selection, data extraction, risk of bias assessment, and quality of evidence evaluation. The results of the included studies were synthesized narratively and statistically, as appropriate.

Results

We included 3.8% (6/151) of the retrieved studies. The results of individual studies were contradictory regarding the effectiveness of mobile text messaging on PA. However, a meta-analysis of the results of 5 studies showed no statistically significant effect (P=.16) of text messages on PA in comparison with no intervention. A meta-analysis of the findings of 2 studies showed a nonsignificant effect (P=.14) of text messages on glycemic control. Of the 541 studies, 2 (0.4%) found a nonsignificant effect of text messages on anthropometric measures (weight and BMI).

Conclusions

We could not draw a definitive conclusion regarding the effectiveness of text messaging on PA, glycemic control, weight, or BMI among patients with T2MD, given the limited number of included studies and their high risk of bias. Therefore, there is a need for more high-quality primary studies.

Dietary fructose and its association with the metabolic syndrome in Lebanese healthy adults: a cross-sectional study

BACKGROUND

Epidemiological studies investigating the association between dietary fructose intake and the metabolic syndrome (MetS) are scarce and have produced controversial findings. This study aimed at (1) assessing total dietary fructose intake in a sample of Lebanese healthy adults, and determining the intake levels of natural vs. added fructose; (2) investigating the association of dietary fructose with MetS; and (3) identifying the socioeconomic and lifestyle factors associated with high fructose intake.

METHODS

A cross-sectional survey was conducted on a representative sample of adults living in Beirut, Lebanon (n = 283). Anthropometric and biochemical data were collected, and dietary intake was assessed using a food frequency questionnaire. Intakes of naturally-occurring fructose from fructose-containing food sources, such as fruits, vegetables, honey, were considered as "natural fructose". Acknowledging that the most common form of added sugar in commodities is sucrose or High Fructose Corn Syrup (HFCS), 50% of added sugar in food products was considered as added fructose. Total dietary fructose intake was calculated by summing up natural and added fructose intakes. Logistic regression analyses were conducted to investigate the association of total, added and natural fructose intakes with the MetS and to identify the socioeconomic predictors of high fructose intake.

RESULTS

Mean intake of total fructose was estimated at 51.42 ± 35.54 g/day, representing 6.58 ± 3.71% of energy intakes (EI). Natural and added fructose intakes were estimated at 12.29 ± 8.57 and 39.12 ± 34.10 g/day (1.78 ± 1.41% EI and 4.80 ± 3.56% EI), respectively. Participants in the highest quartile of total and added fructose intakes had higher odds of MetS (OR = 2.84, 95%CI: 1.01, 7.94 and OR = 3.18, 95%CI: 1.06, 9.49, respectively). In contrast, natural fructose intake was not associated with MetS. Age, gender and crowding index were identified as factors that may modulate dietary fructose intakes.

CONCLUSIONS

The observed association between high added fructose intake and the MetS highlights the need for public health strategies aimed at limiting sugar intake from industrialized foods and promoting healthier dietary patterns in Lebanon.

Comparison of Lean Mass in Women With and Without Heart Disease

PURPOSE

This proof-of-concept study compared lean mass (LM) between women with heart disease (HD) and without HD.

METHODS

Fifty-six community-dwelling women were pair-matched by age. Heart disease was defined using criteria from the US Behavioral Risk Factor Surveillance System. Body composition was measured using multifrequency bioelectrical impedance analysis. Relative LM was calculated against height (kg/m2) as the lean mass index (LMI). Sarcopenia was defined as an LMI <15.0 kg/m2. Strength was measured with a handgrip dynamometer, arm curl test, and chair stand test.

RESULTS

Those with HD had significantly less absolute (38.2 ± 0.8 vs 43.5 ± 1.0 kg; P < .001) and relative (15.3 ± 0.3 vs 16.2 ± 0.3 kg/m2, P = .015) LM compared with those without HD. Body mass was significantly greater for those without HD (76.1 ± 2.1 vs 68.4 ± 2.1 kg; P = .013) and there were no differences in fat mass. Upper body strength was significantly less and lower body strength was diminished but not significantly different in those with HD compared to those without HD (handgrip: P = .016; arm curl: P < .001; chair stand: P = .066).

CONCLUSIONS

In this group of community-dwelling women, those who reported a diagnosis of HD had significantly less LM than those without HD. Although neither group was classified as sarcopenic, women with HD were at greater risk due to lower relative LM. Based on our findings, during cardiac rehabilitation clinicians should counsel women regarding resistance exercise for maintenance of LM in addition to strength.

Dietary Habits and Lifestyle During Coronavirus Pandemic Lockdown: Experience From Lebanon

This study aimed to examine the impact of quarantine on eating habits and lifestyle behaviors among the Lebanese adult population. A cross-sectional study was conducted using an online questionnaire designed on Google Forms between 3 June and 28 June 2020. The survey questions were adapted from the Short Food Frequency Questionnaire, the International Physical Activity Questionnaire Short Form, and the second version of the Copenhagen Psychosocial Questionnaire. A total of 2,507 adults completed the questionnaire. During the lockdown, 32.8% claimed weight gain, 44.7% did not eat fruits daily, 35.3% did not eat vegetables on daily basis, and 72.9% reported drinking less than eight cups of water per day. Moreover, there was a significant increase in the number of meals consumed per day, consumption of homemade meals, sedentary time, stress, and sleeping disturbances during the pandemic compared to before the pandemic (all p < 0.001). However, there was a significant decrease in physical activity engagement, sleep quality, and energy level during the lockdown compared to before the pandemic (all p < 0.001). The study highlights that the COVID-19 lockdown was associated with unfavorable changes in dietary habits and lifestyle behaviors in Lebanon. Sleep and mental health were also negatively impacted by the pandemic.

Measurement and prevalence of adult physical activity levels in Arab countries

OBJECTIVES

This study aims to examine the reported prevalence of sufficient physical activity among adults in Arab countries and to determine the use of validated instruments for assessing physical activity.

STUDY DESIGN

This is a systematic literature review.

METHODS

This review follows recommendations outlined in the Meta-Analysis of Observational Studies in Epidemiology guidelines. The protocol for this study was preregistered with PROSPERO. Cross-sectional, cohort and intervention studies with a minimum of 300 adults aged ≥18 years assessing physical activity using a questionnaire or other self-report measure in the Arabic language were identified from seven electronic databases (MEDLINE, Embase, Cochrane Database of Systematic Reviews, CINAHL, PsycINFO, SPORTDiscu and PubMed). Databases were searched from 1st January 2008 to 17th September 2018. Descriptive analysis was performed using frequency and percentages. The prevalence of physical activity was calculated as the average prevalence for the reported percentages from the studies with similar tools.

RESULTS

Fifty studies involving 298,242 participants were included in this review. The mean (range) sample size was 5964.8.1 (323-197,681). Data were collected from participants in 16 of the 22 Arab countries. Great variation exists across the studies in determining whether adults were sufficiently active or not. Twenty studies reported usable data from the Global Physical Activity Questionnaire and the International Physical Activity Questionnaire (moderate & high categories). In these studies, prevalence of physical activity ranged from 34.2 to 96.9%. It was not possible to compare the other studies owing to variation in instruments used to assess physical activity and in the case definition used for 'physically active'.

CONCLUSIONS

This study highlights the need for wider reporting of physical activity and the adoption of valid and reliable instruments to support the development of evidence-informed policy and programmes at both country and regional level. International tools need to be correctly validated, or context-specific tools must be developed to accurately measure physical activity.

Prevalence and Correlates of Hypertension Unawareness among Lebanese Adults: The Need to Target Those “Left Behind”

Introduction. Hypertension unawareness is context-specific, and our understanding of factors associated with it has implications on primary healthcare practices locally and contributes to achieving cardiovascular disease (CVD) targets, globally. In this study, we examine the prevalence and correlates of hypertension unawareness among adult Lebanese population. Methods. The study sample included a nationally representative sample of 2214 adults ≥25 years of age from the Noncommunicable Disease (NCD) Risk Factor WHO-STEPS cross-sectional survey conducted in Lebanon. In the first step, hypertension was assessed based on reported morbidity using face-to-face interviews, and in the second step, based on blood pressure (BP) measurement. We defined hypertension prevalence as systolic/diastolic blood pressure ≥140/90 mmHg and/or ongoing treatment for hypertension. Hypertension unawareness was described as lack of prior knowledge of hypertensive status. Those responding negatively to the face-to-face interview question “whether they had ever been told by a health worker that they have hypertension” were labelled as “apparently healthy.” Results. Overall prevalence of hypertension was 30.7%. A total of 369 subjects were unaware of their condition, representing 51.8% of all hypertensives and 15.9% of the apparently healthy. Multivariable analysis controlling for a number of confounders showed that, among apparently healthy participants, insurance coverage and contact with healthcare services were not associated with higher likelihood for hypertension awareness. Among all hypertensives, hypertension unawareness was significantly higher in the young, those with BMI <25 kg/m2 (adjusted OR (aOR): 2.52; 95% CI: 1.35–4.69), no CVD (aOR: 3.30; 95% CI: 1.74–6.29), and participants with no reported family history of hypertension (aOR: 4.87; 95% CI: 2.89–8.22), compared to their counterparts. Conclusion. In Lebanon, unawareness of hypertension occurred in those clinically least perceived to be at risk. These findings are key for optimizing current screening practices and informing NCD prevention efforts in the country and contribute to achieving global targets of the SDGs of “leaving no one behind.”

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.

Dynamics of non-communicable disease prevention, diagnosis and control in Lebanon, a fragile setting

BACKGROUND

Non-communicable diseases (NCD) present an increasing global health challenge, particularly for settings affected by fragility where access to care may be disrupted, and where high-quality continuous care delivery is difficult to achieve. This study documents the complex dynamics of NCD prevention and management in the fragile setting of rural Beqaa, Lebanon.

METHODS

Participatory system dynamics methods were used, including 30 semi-structured interviews and three Group Model Building (GMB) workshops. Participants included health care providers offering NCD care, and Lebanese host- and Syrian refugees community members affected by NCDs.

RESULTS

Participants across all groups articulated a shared complex understanding of both the structural and direct determinants behind NCD onset. Lebanese and Syrian community members further identified several barriers to health seeking, including restrictions in health coverage, limited availability of services in the Beqaa and perceptions of poor-quality care. Health providers and community members described a health system overtly focused on disease control and overwhelmed by delivery of care to people living with NCD across both communities.

CONCLUSION

Participants across all groups agreed on the need for health promotion and primary prevention activities and identified priority interventions in these areas.

Physical activity levels and related sociodemographic factors among Iranian adults: Results from a population-based national STEPS survey

Background: Physical inactivity (PA) is one of the leading modifiable risk factors for noncommunicable diseases (NCDs) worldwide. This study aimed to determine PA levels and related sociodemographic factors as risk factors for NCDs among Iranian adults.

Methods: In this cross sectional study, data were collected from the sixth nationwide STEPS survey in 31 provinces of Iran. A total of 6100 individuals aged 18-64 years were selected by a multistage cluster sampling method, and their PA levels were assessed using the Global Physical Activity Questionnaire (GPAQ). Data were analyzed using descriptive methods and analytical tests, including chi-square, ANOVA, and independent t tests in SPSS version 21 software.

Results: The prevalence of vigorous, moderate, and low levels of PA was 36.3% (95%CI:35.1-37.5), 29.2% (95%CI:28-30.3), and 34.5% (95%CI:33.3-35.7) in participants, respectively. The mean ± SD of total MET-min/week was 1842.3±2619.3. Total mean ± SD duration of PA was 98.2 ± 115 min/week (125.8±142.6 and 77.2±84.5 min/week in men and women, respectively). Transport-related PA and severe PA at work had large and small contributions to overall PA, respectively. Urbanization, sex, age, family size, and occupation status were identified as factors associated with PA levels (p<0.001).

Conclusion: This study revealed a significant prevalence of low PA among the target population and some sociodemographic characteristics identified as factors associated with PA. Identification of these factors can develop more effective interventions to promote PA.

Comprehensive Review of Cardiovascular Diseases, Diabetes, and Hypercholesterolemia in Lebanon

The Middle East and North Africa regions, including Lebanon, have recently witnessed rapid urbanization and modernization over the last couple of decades that has led to a dramatic transformation affecting lifestyle and diet. The World Health Organization reports that the leading cause of death in Lebanon is due to cardiovascular disease (CVD) at 47% of all-cause mortality. Over the last 30 years, especially the last 10, the population of Lebanon has changed dramatically due to the effect of wars in the region and refugees seeking asylum. With a population of around 4.5 million and a relatively high rate of consanguinity in Lebanon, a variety of novel mutations have been discovered explaining several familial causes of hypercholesterolemia, diabetes mellitus, congenital heart disease, and cardiomyopathies. Due to the Syrian civil war, 1.5 million Syrian refugees now reside in Lebanon in either low-income housing or tented settlements. A National Institutes of Health study is examining diabetes and CVD in Syrian refugees in comparison to native Lebanese. We provide the first review of CVD in Lebanon in its metabolic component including coronary artery disease and its risk factors, mainly hyperlipidemia and diabetes mellitus, and its structural component, including congenital heart disease, valvular heart disease, cardiomyopathies, and heart failure. The knowledge in this review has been compiled to guide clinicians and assist researchers in efforts to recognize risk factors for disease, improve delivery of health care, and prevent and treat CVDs in Lebanon, both for the native Lebanese and Syrian refugees.

Physical activity and its associated factors in females with type 2 diabetes in Riyadh, Saudi Arabia

Despite the benefits of physical activity (PA) for the management of type 2 diabetes Mellitus (T2DM), the topic of PA is poorly addressed in Saudi Arabia (SA), especially in females with T2DM. The present study examined PA and its associated factors in females with T2DM in Riyadh, Saudi Arabia. This observational cross-sectional study was performed in a random sample of 372 women with T2DM. A face-to-face interview that covered PA, health and environmental correlates of PA was performed. Discriminant analysis was used to determine which barriers had the greatest impact on PA in these women. The results showed that approximately 26.3% of the study participants met PA recommendations. Multivariate linear regression revealed lower levels of PA were associated with women who had more than three children (β = -0.17) compared to women with no children, older age (β = -0.18), women with a duration of diabetes ≥ 6 years (β = -0.16), women who were obese (β = -0.23), women with no family support (β = -0.20), no friend support (β = -0.13) and no healthcare provider support (β = -0.14). Discriminant analysis indicated that culture and tradition, lack of skills and knowledge, safety, fatigue, lack of time, weather conditions, and lack of facilities were the barriers that differentiated between the women who met and those who did not meet the PA recommendations. The present study suggests that the prevalence of PA is low and number of children, age, duration of diabetes, Obesity, family support, friend support and healthcare provider support are identified correlates of PA. These findings are valuable and should be used to design and implement future PA interventions, especially for women with T2DM. Healthcare providers may improve exercise levels and identify the specific barriers to reaching the recommended level of PA to improve health outcomes for each patient.

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.

Factors Associated with Meeting Current Recommendation for Physical Activity in Scottish Adults with Diabetes

It remains unclear which factors are instrumental in meeting the recommended physical activity in people with diabetes. We, therefore, aimed to determine the sociodemographic, health-related behavior and clinical factors associated with meeting the recommended levels of physical activity in Scottish adults with diabetes. The study was based on the nationally-representative cross-sectional Scottish Health Surveys (2014–2017). The study participants included a sub-sample of 1259 adults (≥16 years old) with diabetes. Physical activity was evaluated using international guidelines. Overall, 34.1% of the subjects met the recommended levels of physical activity. Independent determinants of meeting the recommended levels of physical activity include male gender (odds ratio (OR) 1.47; 95% confidence interval (CI) 1.07–2.00) and being a non-smoker (OR 1.62; 95% CI 1.02–2.56). Furthermore, meeting the recommended physical activity levels decreased with age (OR 0.96; 95% CI 0.95–0.97), having a longstanding illness (OR 0.56; 95% CI 0.34–0.93) and body mass index (OR 0.94; 95% CI 0.92–0.97), but increased with higher fruit and vegetable intake (OR 1.16; 95% CI 1.07–1.25) and mental wellbeing (OR 1.04; 95% CI 1.02–1.06). Implementation of health promotion programs that target the identified determinants is needed to improve the recommended levels of physical activity among adults with diabetes.

Physical activity level and its barriers among patients with type 2 diabetes mellitus attending primary healthcare centers in Saudi Arabia

Introduction

Physical activity (PA) plays an important role in diabetes management. This study aimed to evaluate the level of PA and the barriers toward practicing regular PA among patients with type 2 diabetes mellitus (T2DM) attending primary healthcare centers (PHCs) in Jeddah during 2018.

Materials and Methods

A total of 250 patients were interviewed face-to-face in three PHCs. Two questionnaires were used in this study. The first questionnaire measured the level of PA of the participants. The second questionnaire aimed to identify barriers to PA. For analysis, simple descriptive statistics, Chi-square, T-test, and analysis of variance were used.

Results

The prevalence of physical inactivity was found to be 38.4%. Males and females composed 40% and 37.4% of the participants, respectively. Lack of social support, lack of energy, fear of injury, and lack of skills were identified as significant barriers to PA according to the level of PA.

Conclusion

Our findings may provide baseline data for future research on this topic and information for healthcare professionals to improve their efforts in promoting the overall health of patients with T2DM.

Objectively Measured Physical Activity of Vietnamese Adults With Type 2 Diabetes: Opportunities to Intervene

OBJECTIVES

To objectively determine and compare the physical activity (PA) levels of adults newly diagnosed with type 2 diabetes (T2D) and adults without T2D in Vietnam using an accelerometer.

METHODS

A total of 120 participants with newly diagnosed T2D and 120 adults without T2D were recruited from a large hospital in Hanoi, the capital city of Vietnam. All participants wore an ActiGraph GT3X accelerometer for at least 5 days, including 1 weekend day. Freedson cut-off points were used to estimate different intensities of PA. In addition, comparisons between groups were made with respect to achieving the World Health Organization (WHO) and International Diabetes Federation (IDF) recommended PA guidelines.

RESULTS

Men with T2D had significantly lower levels of PA than men without T2D. The respective multivariable-adjusted mean values of daily step count, daily light-intensity, moderate-intensity, and moderate-to-vigorous-intensity PA were approximately 14%, 19%, and 22% lower in the men with T2D than in their non-T2D counterparts. However, women with T2D accumulated a greater number of steps per day than women without T2D. Only 59.2% of the adults with T2D met the minimum recommended level of PA (WHO and IDF), compared to 74.2% of adults without T2D (p&lt;0.05). After adjusting for potential confounders, participants with T2D experienced 50.0% significantly lower odds of achieving PA recommendations.

CONCLUSIONS

Vietnamese men with T2D were less physically active than those without T2D, and adults with T2D were less likely to meet PA guidelines. The results suggest a need for integrating PA into the self-management of this chronic condition.

Knowledge of the physical activity guidelines and factors associated with physical activity participation among adults in Harar town, eastern Ethiopia

Objectives

We assessed knowledge of the physical activity guidelines and factors associated with physical activity participation among adults in Harar town, eastern Ethiopia.

Design

A cross-sectional study of 590 adults in Harar town with face-to-face interview.

Results

Only 27% of participants had good knowledge of the physical activity guidelines. The extent of physical activity participation was 54% (95% CI 50.0% to 58.4%). Male participants (adjusted OR (AOR) 2.14; 95% CI 1.49 to 3.07), educational status of college diploma and above (AOR 2.06; 95% CI 1.09 to 3.89), sitting less than 2 hours per day (AOR 1.82; 95% CI: 1.17% to 2.83%) and good knowledge of physical activity (AOR 3.03; 95% CI 1.98 to 4.64) were associated with physical activity participation.

Conclusions

There is limited knowledge of physical activity guideline in the study area.

'MOVEdiabetes': a cluster randomized controlled trial to increase physical activity in adults with type 2 diabetes in primary health in Oman

OBJECTIVE

This study examined the impact of a multicomponent intervention to increase physical activity (PA) in adults with type 2 diabetes (T2D) in Oman.

RESEARCH DESIGN AND METHODS

This is a cluster randomized controlled trial in eight primary health centers. Participants were physically inactive, aged ≥18 years, and with no contraindication to PA. Patients attending intervention health centers (n=4) received the 'MOVEdiabetes' intervention, which consisted of personalized, individual face-to-face consultations by dietitians. Pedometers and monthly telephone WhatsApp messages were also used. Patients attending comparison health centers received usual care. The primary outcome was change in PA [Metabolic Equivalent(MET).min/week] after 12 months assessed by the Global Physical Activity Questionnaire. The secondary outcomes were changes in daily step counts, sitting time, weight, body mass index, glycated hemoglobin, blood pressure and lipids.

RESULTS

Of the 232 participants (59.1% female, mean (SD) age 44.2 (8.1) years), 75% completed the study. At 12 months, the mean change in MET.min/week was +631.3 (95% CI 369.4 to 893.2) in the intervention group (IG) vs +183.2 (95% CI 83.3 to 283.0) in the comparison group, with a significant between-group difference of +447.4 (95% CI 150.7 to 744.1). The odds of meeting PA recommendations were 1.9 times higher in the IG (95% CI 1.2 to 3.3). Significant between-group differences in favor of IG were detected for mean steps/day (+757, 95% CI 18 to 1531) and sitting time hours/ per day (-1.5, 95% CI -2.4 to -0.7). Clinical measures of systolic and diastolic blood pressure and triglycerides also showed significant intervention effects.

CONCLUSIONS

'MOVEdiabetes' was effective in increasing PA, the likelihood of meeting PA recommendations, and providing cardioprotective benefits in adults with T2D attending primary care.

The effects of type 2 diabetes mellitus and its complications on physical and pulmonary functions: A case-control study

AIMS

This study was planned to determine the effects of type 2 diabetes mellitus (DM) and its complications on physical and pulmonary functions. Methods: A total of 110 individuals aged 40-65 years were included in the study, 58 with type 2 DM (study group) and 52 without DM (control group). Physical activity level, functional capacity, pulmonary function, and comorbidity levels were compared between the groups. Results: The mean age of the individuals was 52.42 ± 5.88 years. Six-minute walk test distance was 507.2 ± 51.70 m in the study group and 532.23 ± 50.32 m in the control group (p < 0.05, Cohen's d = 0.49). The pulmonary function test results of the study and control groups were determined as forced vital capacity (FVC) (%): 99.17 ± 14.13 and 104.65 ± 16.01 (p > 0.05), forced expiratory volume in one second (FEV1) (%): 96.78 ± 14.43 and 99.73 ± 15.80 (p > 0.05), and FEV1/FVC ratio: 81.97 ± 4.62 and 80.16 ± 5.27 (p > 0.05), respectively. The Charlson Comorbidity Index scores of the study and control groups were 1.83 ± 0.82 and 0.12 ± 0.32 (p < 0.05). Conclusions: Type 2 DM was associated with lower functional capacity and higher rates of comorbid diseases. Therefore, potential causes of these parameters should be considered in the rehabilitation of type 2 diabetic patients.

Physical inactivity, gender and culture in Arab countries: a systematic assessment of the literature

Background

Physical inactivity is associated with excess weight and adverse health outcomes. We synthesize the evidence on physical inactivity and its social determinants in Arab countries, with special attention to gender and cultural context.

Methods

We searched MEDLINE, Popline, and SSCI for articles published between 2000 and 2016, assessing the prevalence of physical inactivity and its social determinants. We also included national survey reports on physical activity, and searched for analyses of the social context of physical activity.

Results

We found 172 articles meeting inclusion criteria. Standardized data are available from surveys by the World Health Organization for almost all countries, but journal articles show great variability in definitions, measurements and methodology. Prevalence of inactivity among adults and children/adolescents is high across countries, and is higher among women. Some determinants of physical inactivity in the region (age, gender, low education) are shared with other regions, but specific aspects of the cultural context of the region seem particularly discouraging of physical activity. We draw on social science studies to gain insights into why this is so.

Conclusions

Physical inactivity among Arab adults and children/adolescents is high. Studies using harmonized approaches, rigorous analytic techniques and a deeper examination of context are needed to design appropriate interventions.

A Self-Directed Mobile Intervention (WaznApp) to Promote Weight Control Among Employees at a Lebanese University: Protocol for a Feasibility Pilot Randomized Controlled Trial

Background

Overweight and obesity have become major health problems globally with more than 1.9 billion overweight adults. In Lebanon, the prevalence of obesity and overweight is 65.4% combined. Risk factors of obesity and overweight are preventable and can be addressed by modifications in the environment and in an individual’s lifestyle. Mobile technologies are increasingly used in behavioral, self-directed weight management interventions, providing users with additional opportunities to attain weight control (weight loss, weight gain prevention, etc). Mobile apps may allow for the delivery of Just-in-Time Adaptive Interventions (JITAIs), which provide support through skill building, emotional support, and instrumental support, following the participants’ progress. A few commercially available apps offer JITAI features, but no studies have tested their efficacy.

Objective

The primary objective of this study is to examine the feasibility of a self-directed weight loss intervention, targeting employees of an academic institution, using a virtual coaching app with JITAI features (Lark) and a self-help calorie-counting app (MyFitnessPal). The secondary objective is to estimate the effects of the intervention on main study outcomes.

Methods

This study is a single-center, parallel, randomized controlled trial with 2 study arms (intervention and control). Participants will be randomly allocated in equal proportions to the intervention (Lark) and control groups (MyFitnessPal). To be eligible for this study, participants must be employed full- or part-time at the university or its medical center, able to read English, have a smartphone, and be interested in controlling their weight. Recruitment strategies entail email invitations, printed posters, and social media postings. We will assess quantitative rates of recruitment, adherence, and retention, self-reported app quality using the user version of the Mobile App Rating Scale. We will also assess changes in weight-related outcomes (absolute weight and waist circumference), behavioral outcomes (physical activity and diet), and cognitive factors (motivation to participate in the trial and to manage weight).

Results

WaznApp was funded in June 2017, and recruitment started in March 2018.

Conclusions

This study will provide information as to whether the selected mobile apps offer a feasible solution for promoting weight management in an academic workplace. The results will inform a larger trial whose results might be replicated in similar workplaces in Lebanon and the Middle East and North Africa region, and will be used as a benchmark for further investigations in other settings and similar target groups.

Knowledge and practice of patients with diabetes mellitus in Lebanon: a cross-sectional study

Background

The objective of this study was to assess the knowledge and practice of Lebanese patients living with diabetes mellitus in regards to their diabetes self- management.

Methods

A cross-sectional study, conducted between January and June 2015, enrolled 207 urban adult patients with diabetes mellitus from community pharmacies while purchasing their diabetes medications. Their knowledge and self-management practices were assessed using a structured anonymous interview survey questionnaire.

Results

The mean age of the participants was 60.2 ± 15.5 years, and the Male/Female ratio was 1.38. The mean knowledge score was 2.34 ± 0.88 points (out of 6). Very few participants (17.4%) knew their current medication side effects. The mean practice score was 5.86 ± 1.77 points (out of 8). Only 15.9% of patients reported current physical activity. A multiple linear analysis showed that those with a university degree had a significantly higher knowledge (Beta = 0.448, p = 0.001) and practice score (Beta = 0.523 p = 0.047) than those with intermediate or primary schooling. Those who reported following a special diabetes diet had a higher knowledge score (Beta = 0.482, p < 0.001) than those who did not. Knowledge score and practice score were highly correlated (Beta = 0.844, p < 0.001). There was no significant differential by gender and age for knowledge and practice scores.

Conclusions

The knowledge and practice scores of patients with diabetes mellitus were not satisfactory. Well-targeted interventions are needed, such as improving the communication between the pharmacist and people living with diabetes. The observed low adherence to physical exercise among patients with diabetes should also be addressed.

Epidemiology and correlates of osteoporotic fractures among type 2 diabetic patients

This study analyzed data on 87,224 osteoporotic patients with up to 18 years of computerized medical history. Patients with osteoporosis and type 2 diabetes had higher bone density yet more fractures than non-diabetic osteoporotic patients. Fracture incidence among the diabetic patients was associated with retinopathy and cardiovascular disease, but not with diabetes duration.

PURPOSE

Little is known about the association between type 2 diabetes mellitus (T2DM) and fragility fractures or the mechanism(s) involved. We examined fracture correlates among T2DM patients with osteoporosis.

METHODS

We used electronic health records of an osteoporosis (OP) registry cross-linked with a diabetes registry of a large payer provider healthcare organization in Israel. A cross-sectional analysis compared osteoporosis patients with and without T2DM, and a longitudinal Cox proportional hazard regression was used to identify incident fracture correlates.

RESULTS

As of December 2015 a total of 87,224 current OP patients were identified, of whom 15,700 (18%) had T2DM. The T2DM OP patients were characterized by older age (mean 74.6 vs. 69.5), more males (20.3 vs. 14.0%), and a higher rate of chronic comorbidities compared to OP without diabetes. All major OP fractures (hip, spine, humerus, and forearm) were significantly more prevalent among T2DM OP patients (44 vs. 32%), with an overall age-standardized ratio of 1.22 (95% CI 1.19 to 1.25) and 1.15 (95% CI 1.10 to 1.21) for females and males respectively. The average T-scores were higher (femur neck - 1.8 vs. - 1.9, total hip - 1.2 vs. - 1.6, and vertebrae - 1.3 vs. - 1.7) for the T2DM OP patients compared to the non-T2DM OP patients. Among women with coexisting T2DM and osteoporosis (n = 10,812), fracture incidence was significantly associated with retinopathy (HR = 1.24, 95% CI 1.05 to 1.47) and cardiovascular disease (HR = 1.22, 95% CI 1.10 to 1.36) after controlling for age, bone mineral density T-score, rheumatoid arthritis, glucocorticoids, alcohol, and smoking).

CONCLUSION

This large population-based study confirms the higher fracture risk of osteoporotic patients with T2DM, as compared to osteoporotic patients without T2DM, despite higher bone mineral density levels. The presence of micro- and macrovascular disease appears to increase this risk.

Short Telomere Length is Associated with Aging, Central Obesity, Poor Sleep and Hypertension in Lebanese Individuals

In Lebanon, data stemming from national cross-sectional surveys indicated significant increasing trends in the prevalence of cardiovascular diseases and associated behavioral and age-related risk factors. To our knowledge, no data are available on relative telomere length (RTL) as a potential biomarker for age-related diseases in a Lebanese population. The aim of this study was to evaluate whether there is an association between RTL and demographic characteristics, lifestyle habits and diseases in the Lebanese. This was a cross-sectional study of 497 Lebanese subjects. Peripheral blood RTL was measured by amplifying telomere and single copy gene using real-time PCR. Mean ± SD RTL was 1.42 ± 0.83, and it was categorized into 3 tertiles. Older age (P=0.002) and wider waist circumference (WC) (P=0.001) were statistically significantly associated with shorter RTL. Multinomial logistic regression showed that subjects who had some level of sleeping difficulty had a statistically significantly shorter RTL when compared to those with no sleeping difficulties at all [OR (95% CI): 2.01 (1.11-3.62) in the first RTL tertile]. Importantly, statistically significantly shorter RTL was found with every additional 10 cm of WC [OR (95% CI): 1.30 (1.11-1.52) for first RTL tertile]. In addition, and after performing the multivariate logistic regression and adjusting for “predictors” of RTL, the odds of having hypertension or being treated for hypertension were higher in patients who had shorter RTL: OR (95% CI): 2.45 (1.36-4.44) and 2.28 (1.22-4.26) in the first RTL tertiles respectively with a similar trend, though not statistically significant, in the second RTL tertiles. This is the first study in Lebanon to show an association between age, central obesity, poor sleep and hypertension and RTL. It is hoped that telomere length measurement be potentially used as a biomarker for biological age and age-related diseases and progression in the Lebanese.

Perceived barriers to leisure time physical activity in adults with type 2 diabetes attending primary healthcare in Oman: a cross-sectional survey

OBJECTIVES

Physical activity is fundamental in diabetes management for good metabolic control. This study aimed to identify barriers to performing leisure time physical activity and explore differences based on gender, age, marital status, employment, education, income and perceived stages of change in physical activity in adults with type 2 diabetes in Oman.

DESIGN

Cross-sectional study using an Arabic version of the 'Barriers to Being Active' 27-item questionnaire.

SETTING

Seventeen primary health centres randomly selected in Muscat.

PARTICIPANTS

Individuals>18 years with type 2 diabetes, attending diabetes clinic for >2 years and with no contraindications to performing physical activity.

PRIMARY AND SECONDARY OUTCOME MEASURES

Participants were asked to rate how far different factors influenced their physical activity under the following categories: fear of injury, lack of time, social support, energy, willpower, skills, resources, religion and environment. On a scale of 0-9, barriers were considered important if scored ≥5.

RESULTS

A total of 305 questionnaires were collected. Most (96%) reported at least one barrier to performing leisure time physical activity. Lack of willpower (44.4%), lack of resources (30.5%) and lack of social support (29.2%) were the most frequently reported barriers. Using χ² test, lack of willpower was significantly different in individuals with low versus high income (54.2%vs40%, P=0.002) and in those reporting inactive versus active stages of change for physical activity (50.7%vs34.7%, P=0.029), lack of resources was significantly different in those with low versus high income (40%vs24.3%, P=0.004) and married versus unmarried (33.8%vs18.5%, P=0.018). Lack of social support was significant in females versus males (35.4%vs20.8%, P=0.005).

CONCLUSIONS

The findings can inform the design on physical activity intervention studies by testing the impact of strategies which incorporate ways to address reported barriers including approaches that enhance self-efficacy and social support.

A minimally processed dietary pattern is associated with lower odds of metabolic syndrome among Lebanese adults

OBJECTIVE

To (i) estimate the consumption of minimally processed, processed and ultra-processed foods in a sample of Lebanese adults; (ii) explore patterns of intakes of these food groups; and (iii) investigate the association of the derived patterns with cardiometabolic risk.

DESIGN

Cross-sectional survey. Data collection included dietary assessment using an FFQ and biochemical, anthropometric and blood pressure measurements. Food items were categorized into twenty-five groups based on the NOVA food classification. The contribution of each food group to total energy intake (TEI) was estimated. Patterns of intakes of these food groups were examined using exploratory factor analysis. Multivariate logistic regression analysis was used to evaluate the associations of derived patterns with cardiometabolic risk factors.

SETTING

Greater Beirut area, Lebanon.

SUBJECTS

Adults ≥18 years (n 302) with no prior history of chronic diseases.

RESULTS

Of TEI, 36·53 and 27·10 % were contributed by ultra-processed and minimally processed foods, respectively. Two dietary patterns were identified: the 'ultra-processed' and the 'minimally processed/processed'. The 'ultra-processed' consisted mainly of fast foods, snacks, meat, nuts, sweets and liquor, while the 'minimally processed/processed' consisted mostly of fruits, vegetables, legumes, breads, cheeses, sugar and fats. Participants in the highest quartile of the 'minimally processed/processed' pattern had significantly lower odds for metabolic syndrome (OR=0·18, 95 % CI 0·04, 0·77), hyperglycaemia (OR=0·25, 95 % CI 0·07, 0·98) and low HDL cholesterol (OR=0·17, 95 % CI 0·05, 0·60).

CONCLUSIONS

The study findings may be used for the development of evidence-based interventions aimed at encouraging the consumption of minimally processed foods.

Correlates of physical activity and sitting time in adults with type 2 diabetes attending primary health care in Oman

Background

Despite evidence of the benefits of physical activity in the management of type 2 diabetes, it is poorly addressed in diabetes care. This study aimed to identify the prevalence and correlates of meeting ≥600MET-min/wk. (150 min/wk) of physical activity and sitting time in adults with type 2 diabetes in Oman. Approaches to encourage physical activity in diabetes care were explored.

Methods

A cross-sectional study using the Global Physical Activity Questionnaire was conducted in 17 randomly selected primary health centres in Muscat. Clinical data including co-morbidities were extracted from the health information system. Questions on physical activity preferences and approaches were included. Patients were approached if they were ≥18 years, and had been registered in the diabetes clinic for >2 years.

Results

The questionnaire was completed by 305 people (females 57% and males 43%). Mean age (SD) was 57 (10.8) years and mean BMI (SD) was 31.0 (6.0) kg/m². Duration of diabetes ranged from 2 to 25 (mean 7.6) years. Hypertension (71%) and dyslipidaemia (62%) were common comorbidities. Most (58.4%) had an HbA1c ≥7% indicating poor glycaemic control (55% in males vs 61% in females).

Physical activity recommendations were met by 21.6% of the participants, mainly through leisure activities. Odds of meeting the recommendations were significantly higher in males (OR 4.8, 95% CI 2.5–9.1), individuals ≤57 years (OR 3.0, 95% CI 1.6–5.9), those at active self-reported stages of change for physical activity (OR 2.2, 95% CI 1.2–4.1) and those reporting no barriers to performing physical activity (OR 2.7, 95% CI 1.4–4.9).

Median (25th, 75th percentiles) sitting time was 705 (600, 780) min/d. Older age (>57 years) was associated with longer sitting time (>705 min/d) (OR 2.8, 95% CI 1.7–4.6).

Preferred methods to support physical activity in routine diabetes care were consultations (38%), structured physical activity sessions (13.4%) and referrals to physical activity facilities (5.6%) delivered by a variety of health care providers.

Conclusions

The results suggest that intervention strategies should take account of gender, age, opportunities within daily life to promote active behaviour and readiness to change. Offering physical activity consultations is of interest to this study population, thus development and evaluation of interventions are warranted.

Validity and reliability of an adapted arabic version of the long international physical activity questionnaire

Background

The International Physical Actvity Questionnaire (IPAQ) is a validated tool for physical activity assessment used in many countries however no Arabic version of the long-form of this questionnaire exists to this date. Hence, the aim of this study was to cross-culturally adapt and validate an Arabic version of the long International Physical Activity Questionnaire (AIPAQ) equivalent to the French version (F-IPAQ) in a Lebanese population.

Methods

The guidelines for cross-cultural adaptation provided by the World Health Organization and the International Physical Activity Questionnaire committee were followed. One hundred fifty-nine students and staff members from Saint Joseph University of Beirut were randomly recruited to participate in the study. Items of the A-IPAQ were compared to those from the F-IPAQ for concurrent validity using Spearman’s correlation coefficient. Content validity of the questionnaire was assessed using factor analysis for the A-IPAQ’s items. The physical activity indicators derived from the A-IPAQ were compared with the body mass index (BMI) of the participants for construct validity. The instrument was also evaluated for internal consistency reliability using Cronbach’s alpha and Intraclass Correlation Coefficient (ICC). Finally, thirty-one participants were asked to complete the A-IPAQ on two occasions three weeks apart to examine its test–retest reliability. Bland-Altman analyses were performed to evaluate the extent of agreement between the two versions of the questionnaire and its repeated administrations.

Results

A high correlation was observed between answers of the F-IPAQ and those of the A-IPAQ, with Spearman’s correlation coefficients ranging from 0.91 to 1.00 (p < 0.05). Bland-Altman analysis showed a high level of agreement between the two versions with all values scattered around the mean for total physical activity (mean difference = 5.3 min/week, 95% limits of agreement = −145.2 to 155.8). Negative correlations were observed between MET values and BMI, independent of age, gender or university campus. The A-IPAQ showed a high internal consistency reliability with Cronbach’s alpha ranging from 0.769–1.00 (p < 0.001) and intraclass correlation coefficient (ICC) ranging from 0.625–0.999 (p < 0.001), except for a moderate agreement with the moderate garden/yard activity (alpha = 0.682; ICC = 0.518; p < 0.001). The A-IPAQ had moderate-to-good test-retest reliability for most of its items (ICC ranging from 0.66–0.96; p < 0.001) and the Bland-Altman analysis showed a satisfactory agreement between the two administrations of the A-IPAQ for total physical activity (mean difference = 99.8 min/week, 95% limits of agreement = −1105.3; 1304.9) and total vigorous and moderate physical activity (mean difference = −29.7 min/week, 95% limits of agreement = −777.6; 718.2).

Conclusion

The modified Arabic version of the IPAQ showed acceptable validity and reliability for the assessment of physical activity among Lebanese adults. More studies are necessary in the future to assess its validity compared to a gold-standard criterion measure.

Physical activity and associated factors from a cross-sectional survey among adults in northern Tanzania

BACKGROUND

Insufficient physical activity (PA) is a major contributing factor in the growing problem of non-communicable diseases (NCDs) in urban and rural Sub-Saharan Africa. This study aimed to determine PA and associated factors among adults in Northern Tanzania.

METHODS

We analyzed secondary data from a cross-sectional serological survey nested within the Magu health and demographic sentinel surveillance population in Magu District Northwestern Tanzania. All resident adults aged 15 years and older were invited to participate in the study, and physical activity data were analyzed for 5663 participants. Data were analyzed using Stata version 13.0. We used logistic regression to obtain odds ratios and 95% confidence intervals (CI) for risk factors associated with differences in PA.

RESULTS

In this mainly rural population, 96% reported sufficient PA, with a higher proportion in males (97.3%) compared to females (94.8%). In males the odds of sufficient PA were lower in rural areas compared to urban areas (OR = 0.19; P < 0.001; 95% CI = 0.08-0.42), while in females the odds of sufficient PA were higher in rural areas compared to urban areas (OR = 2.27; P < 0.001; 95%CI = 1.59-3.24). Leisure-related activity was low compared to work-related and transport-related activity. Farmers had a higher odds of sufficient PA than those in professional jobs in both males (OR = 9.75; P < 0.001; 95% CI = 3.68-5.82) and females (OR = 2.83; P = 0.021; 95% CI = 1.17-6.86).

CONCLUSION

The prevalence of PA in this population was high. However, there is need for PA programs to maintain the high level of compliance during and following the transition to a more urban-based culture.

Study protocol for "MOVEdiabetes": a trial to promote physical activity for adults with type 2 diabetes in primary health care in Oman

BACKGROUND

Benefits of physical activity in the management of diabetes are well documented. However, evidence on the effectiveness of interventions integrating physical activity in diabetes care is sparse especially in the countries of the Gulf Cooperation Council. The results from this study will increase our understanding of the use of multi-component interventions aimed at increasing physical activity levels in inactive adults with type 2 diabetes in primary health care in Oman.

METHODS/DESIGN

The study is a one year 1:1 cluster randomized controlled trial of the MOVEdiabetes programme (intervention) versus usual care in eight primary health care centres in Oman. The MOVEdiabetes programme utilizes face to face physical activity consultations promoting 150 min of moderate to vigorous physical activity per week (≥600MET-mins/week), pedometers to self-monitor step counts and monthly telephone WhatsApp messages for follow up support. Inactive adults with type 2 diabetes and no contraindication to physical activity will be recruited over a two months period, and followed up for 12 months. To demonstrate a 50% between group difference in physical activity levels (MET-mins/week) over 12 months, (at a power of 80%, and significance level of 5%), 128 participants would be required to complete the study (64 in each arm). Based on a drop-out rate of 20%, 154 participants would require to be recruited (77 in each arm). Assuming a recruitment rate of 70%, 220 potential eligible participants would need to be approached. The primary outcome is change in levels of physical activity measured by the Global Physical Activity Questionnaire. In addition, accelerometers will be used in a sub group to objectively assess physical activity. Secondary outcomes include changes in metabolic and cardiovascular biomarkers, change in self-reported health, social support, self-efficacy for physical activity, and perceived acceptability of the program. All intervention delivery and support costs will be monitored.

DISCUSSION

This study will contribute to the evidence on the feasibility, cultural acceptability and efficacy of interventional approaches for increasing physical activity in primary care for persons with type 2 diabetes in Oman.

Prevalence of diabetes and impaired fasting glucose in Costa Rica: Costa Rican National Cardiovascular Risk Factors Survey, 2010

BACKGROUND

The projected rising prevalence of diabetes and impaired fasting glucose (IFG) in developing countries warrants careful monitoring. The aim of this study was to present the results of the Costa Rican National Cardiovascular Risk Factors Surveillance System, which provides the first national estimates of diabetes and IFG prevalence among adults in Costa Rica.

METHODS

A cross-sectional survey of 3653 non-institutionalized adults aged ≥20 years (87.8% response rate) following the World Health Organization STEPwise approach was built on a probabilistic sample of the non-institutionalized population during 2010. Known diabetes was defined as self-reported diagnosis, the use of insulin, or hypoglycemic oral treatment as consequence of diabetes during at least the previous 2 weeks before the survey. Unknown diabetes was defined no self-reported diabetes but with venous blood concentrations of fasting glucose >125 mg/dL determined by laboratory testing. Impaired fasting glucose was defined as fasting glucose between 100 and 125 mg/dL among those without diabetes. The prevalence of diabetes and IFG prevalence was estimated according gender, body mass index (BMI), waist circumference (WC), educational level, and physical activity level.

RESULTS

Overall diabetes prevalence was 10.8% (9.5% known and 1.3% unknown diabetes) and IFG prevalence was 16.5%. The prevalence of known diabetes was higher among women >65 years compared with men of the same age group. Both known and unknown diabetes were significantly associated with higher BMI, increased WC, and low education level (P = 0.01).

CONCLUSIONS

The prevalence of diabetes and IFG in Costa Rica is comparable to that in developed countries and indicates an urgent need for effective preventive interventions.

Cigarette smoking in a Middle Eastern country and its association with hospitalisation use: a nationwide cross-sectional study

OBJECTIVES

Little is known about the distribution of cigarette smoking by place and persons at the national level or its burden on healthcare expenditure in countries of the Middle East. We examine in this study the pattern of cigarette smoking by age, gender and geography and assess its association with hospitalisation use in Lebanon, a small middle-income country in the Middle East.

DESIGN

Population-based cross-sectional study.

SETTING

The study draws on data collected as part of the nationwide multistage cluster sample Nutrition and Non-Communicable Disease Risk Factor survey conducted in Lebanon in 2009.

PARTICIPANTS

A total of 2836 Lebanese adults 18 years and over.

MEASURES

Hospitalisation, the outcome variable, was measured using one item and recoded as a dichotomous variable. Cigarette smoking, the main exposure variable, was assessed by examining smoking status and pack-years, capturing intensity, frequency and duration of exposure.

RESULTS

The overall prevalence rate of current smoking in this study was 34.7%, with significantly higher rates in males than females (42.9% and 27.5%, respectively). Close to two-thirds of the study population reported ever being hospitalised (62.8%). Compared to non-smokers, past and current smokers were significantly more likely to be hospitalised, after controlling for sociodemographic and health-related characteristics (OR=2.9, 95% CI 1.26 to 3.34, and OR=1.35, 95% CI 1.12 to 1.63, respectively). Hospitalisation use increased significantly in a dose-response manner with increasing pack-years.

CONCLUSIONS

When compared to regional and international estimates, the prevalence rates of smoking in Lebanon are considerably high, with percentages among women being among the highest in the region. Our findings of increased odds of hospitalisation among ever smokers, net of the effect of comorbidity, underscore the additional burden of smoking on the healthcare bill cost. Continued monitoring of smoking rates and disease surveillance frameworks are warranted in developing countries for policy development and evaluation.

Contribution of modifiable risk factors for hypertension and type-2 diabetes in Peruvian resource-limited settings

Background

It is important to understand the local burden of non-communicable diseases including within-country heterogeneity. The aim of this study was to characterise hypertension and type-2 diabetes profiles across different Peruvian geographical settings emphasising the assessment of modifiable risk factors.

Methods

Analysis of the CRONICAS Cohort Study baseline assessment was conducted. Cardiometabolic outcomes were blood pressure categories (hypertension, prehypertension, normal) and glucose metabolism disorder status (diabetes, prediabetes, normal). Exposures were study setting and six modifiable factors (smoking, alcohol drinking, leisure time and transport-related physical activity levels, TV watching, fruit/vegetables intake and obesity). Poisson regression models were used to report prevalence ratios (PR). Population attributable risks (PAR) were also estimated.

Results

Data from 3238 participants, 48.3% male, mean age 45.3 years, were analysed. Age-standardised (WHO population) prevalence of prehypertension and hypertension was 24% and 16%, whereas for prediabetes and type-2 diabetes it was 18% and 6%, respectively. Outcomes varied according to study setting (p<0.001). In multivariable model, hypertension was higher among daily smokers (PR 1.76), heavy alcohol drinkers (PR 1.61) and the obese (PR 2.06); whereas only obesity (PR 2.26) increased the prevalence of diabetes. PAR showed that obesity was an important determinant for hypertension (15.7%) and type-2 diabetes (23.9%).

Conclusions

There is an evident heterogeneity in the prevalence of and risk factors for hypertension and diabetes within Peru. Prehypertension and prediabetes are highly prevalent across settings. Our results emphasise the need of understanding the epidemiology of cardiometabolic conditions to appropriately implement interventions to tackle the burden of non-communicable diseases.

The use of expensive technologies instead of simple, sound and effective lifestyle interventions: a perpetual delusion

A dangerous distortion of priorities seems to be currently apparent in the dominant approaches to major public health problems, including cardiovascular disease, diabetes, obesity, cancer and some infectious diseases. Relevant examples suggest an apparently inappropriate tendency to prioritise technocratic, partial solutions rather than confronting their true behavioural and structural determinants. Technically oriented preventive medicine often takes excessive precedence over simpler, more sensible approaches to modify lifestyles, the environment and the social structure. Structural factors (social, cultural, financial, familiar, educational, political or ideological factors) that act as determinants of individual behaviours should be effectively addressed to confront the essential causes of the most prevalent and important health problems. Some consumer-directed commercial forces seem to be increasingly driving many aspects of the current sociocultural environment, and may eventually compromise the main pursuits of public health. Population-wide strategies are needed to create a healthy sociocultural environment and to empower individuals and make themselves resistant to these adverse environmental and structural pressures. Otherwise most public health interventions will most likely end in failures.
