Obesity in a rural and an urban Palestinian West Bank population

OBJECTIVE: To compare the prevalence of obesity, household food consumption patterns, physical activity patterns and smoking between a rural and an urban community in the Palestinian West Bank and to describe the associations of the latter factors with body mass index (BMI).DESIGN: A population-based cross-sectional survey in a rural and an urban Palestinian West Bank community.SUBJECTS: A total of 549 women and 387 men aged 30–65 y, excluding pregnant women.MEASUREMENTS: Obesity was defined as BMI ≥30 kg/m2.RESULTS: The prevalence of obesity was 36.8 and 18.1% in rural women and men, respectively, compared with 49.1 and 30.6% in urban women and men, respectively. The mean difference (s.e) in BMI levels was 1.6 (0.52) kg/m2 between urban and rural women and 0.9 (0.46) kg/m2 in men. At the household level, the mean energy consumption from 25 selected food items was 13.8 MJ (3310 kcal)/consumption unit/day in the rural community compared to 14.5 MJ (3474 kcal)/consumption unit/day in the urban community (P=0.021). BMI was positively associated with age in both men and women and with urban residence in women. BMI was negatively associated with smoking and physical activity in men and with educational level in women.CONCLUSION: BMI was associated with urban residence in women after adjusting for age, smoking, education, physical activity and nutrition-related variables, suggesting that the differences in the conventional determinants of obesity could not fully explain the difference in the prevalence of obesity between the two communities. Among men, the measured determinants explained the rural–urban differences in BMI.

Obesity and selected co-morbidities in an urban Palestinian population

OBJECTIVE: To assess the prevalence of obesity and central obesity in an urban Palestinian population and their associations with selected co-morbidities, including diabetes, hypertension and dyslipidaemia.DESIGN: A population-based cross-sectional survey in an urban Palestinian community.SUBJECTS: Men and women aged 30–65 y residing in the urban community, excluding pregnant women.MEASUREMENTS: According to WHO guidelines, obesity for men and women was defined as BMI≥30 kg m−2, while pre-obesity was defined as BMI 25–29.9 kg m−2. Central obesity was defined as a waist-to-hip ratio (WHR) of >0.90 in men and >0.85 in women.RESULTS: The prevalence of obesity in this population was high at 41% (49% and 30% in women and men, respectively). Central obesity was more prevalent among men (59% compared to 25% in women). After adjusting for the effects of age, sex, smoking and each other, obesity and central obesity were found to be significantly associated with diabetes, low HDL-cholesterol and elevated triglycerides in separate logistic regression analyses. Central obesity was also significantly associated with hypertension (OR 2.26, 95% CI 1.30–3.91).CONCLUSION: Obesity and central obesity are prevalent in the urban Palestinian population. Their associations with diabetes, hypertension, and dyslipidaemia point to a potential rise in cardiovascular disease (CVD). An understanding of the reasons behind the high prevalence of obesity is essential for its prevention as well as for the prevention of the morbidities to which it may lead.

Prevalence and sociodemographic correlates of stunting, underweight, and overweight among Palestinian school adolescents (13-15 years) in two major governorates in the West Bank

BackgroundThere is little information about height and weight status of Palestinian adolescents. The objective of this paper was to assess the prevalence of stunting, underweight, and overweight/obesity among Palestinian school adolescents (13-15 years) and associated sociodemographic factors in 2 major governorates in the West Bank.MethodsA Cross-sectional survey was conducted in 2005 comprising 1942 students in 65 schools in Ramallah and Hebron governorates. Data was collected through self-administered questionnaires from students and parents. Weights and heights were measured. Overweight and obesity were assessed using the 2000 Centers for Disease Control and Prevention (CDC) reference and the International Obesity Task Force (IOTF) criteria. Stunting and underweight were assessed using the 2000 CDC reference.ResultsOverweight/obesity was more prevalent in Ramallah than in Hebron and affected more girls than boys. Using the 2000 CDC reference, the prevalence of overweight and obesity in Ramallah among boys was 9.6% and 8.2%, respectively versus 15.6% and 6.0% among girls (P < 0.01). In Hebron, the corresponding figures were 8.5% and 4.9% for boys and 13.5% and 3.4% for girls (P < 0.01). Using the IOTF criteria, the prevalence of overweight and obesity among boys in Ramallah was 13.3% and 5.2%, respectively versus 18.9% and 3.3% for girls. The prevalence of overweight and obesity among boys in Hebron was 10.9% and 2.2%, respectively versus 14.9% and 2.0% for girls. Overweight/obesity was associated with high standard of living (STL) among boys and with the onset of puberty among girls. More boys were underweight than girls, and the prevalence was higher in Hebron (12.9% and 6.0% in boys and girls, respectively (P < 0.01)) than in Ramallah (9.7% and 3.1% in boys and girls, respectively (p < 0.01)). The prevalence of stunting was similar in both governorates, and was higher among boys (9.2% and 9.4% in Ramallah and Hebron, respectively) than among girls (5.9% and 4.2% in Ramallah and Hebron, respectively). Stunting was negatively associated with fathers education among boys and with urban residence, medium STL and onset of puberty among girls.ConclusionUnder- and overnutrition co-exist among Palestinian adolescents, with differences between sexes. Region, residence, STL, and onset of puberty were associated factors.

Food consumption patterns in a Palestinian West Bank population.

Objective: To describe the food consumption patterns in relation to wealth status and age groups in a Palestinian West Bank village population.Design: Community-based cross-sectional survey of both households and individuals. A list recall method was used at the household level. At the individual level, a short food-frequency questionnaire was used in addition to a 24-h recall without estimates of portion sizes.Setting: A Palestinian semi-rural village in the central West Bank.Subjects: All households and all men and women aged 30–65 y in the study village were invited. All 368 households and 85% (n=500) of eligible individuals participated.Results: The mean energy consumption from 25 selected food items on household level was about 13.8 MJ (3300 kcal)/consumption unit/d (a consumption unit corresponds to the expected energy requirement for an adult male). The proportion of dietary energy from fat and the consumption of most animal products was highest among the wealthiest households, and the opposite trend was seen for the consumption of wheat flour and lentils. There seems to be an ongoing trend of increasing consumption of processed products rich in sugar among the younger age groups.Conclusion: Shortage of dietary energy on the household level did not seem to be a problem in this population, even among the poorest. Differences in food consumption patterns between the poor and the wealthy, including a higher percentage of energy from fat among the wealthy, may be to the disadvantage of the wealthy with respect to some diet-related chronic diseases.Sponsorship: The Norwegian Universities’ Committee for Development Research (NUFU).

Type 2 diabetes mellitus, impaired glucose tolerance and associated factors in a rural Palestinian village

SUMMARY

Cesarean section deliveries in the occupied Palestinian territory (oPt): An analysis of the 2006 Palestinian Family Health Survey

Objective Against the backdrop of a rise in cesarean section deliveries from 6.0% in 1996 to 14.8% in 2006, the objective of this study was to investigate socio-demographic, clinical and service-related factors associated with cesarean sections in the occupied Palestinian territory. Methods Data from the Palestinian Family Health Survey 2006 were used to examine last births in the 5 years preceding the survey to women aged 15–49 years. Bivariate and multivariate associations between type of delivery (dependent variable) and selected factors were analyzed using logistic regression. Selected maternal outcomes were also investigated with type of delivery as the independent variable. Results Cesarean section deliveries were significantly associated with maternal age (35+ years), primiparity, low birth weight and residence area in the West Bank and Gaza. There was no significant difference in the prevalence of cesarean deliveries by sector in the West Bank, but in Gaza, they were significantly more common in the governmental sector. Conclusions There is a need for detailed audits of cesarean section deliveries, nationally and at the facility level, in order to avoid unnecessary interventions in the context of high fertility, rising poverty and fragmented health services. Variations by governorate should be studied further for focused interventions.

Anaemia prevalence and associated sociodemographic and dietary factors among Palestinian adolescents in the West Bank

Anaemia still persists among children and women of childbearing age in Palestine. We investigated the prevalence of anaemia and associated factors among Palestinian school adolescents (aged 13-15 years) in Ramallah and Hebron governorates. Haemoglobin levels were measured to assess the prevalence of anaemia. The prevalence of anaemia was significantly higher in Hebron than in Ramallah among boys (22.5% versus 6.0% respectively), while among girls the figures were similar (9.2% and 9.3% respectively). Linear binomial regression analysis showed that among boys, anaemia was independently associated with residence in Hebron and higher standard of living, while among girls, anaemia was associated with higher fathers education. Consumption of iron-rich foods, as recorded in food frequency questionnaires, had no significant effects on anaemia prevalence in both boys and girls.

Prevalence of Chlamydia trachomatis infection in the general population of women in Qatar

Objectives The Arabian Gulf region has limited epidemiological data related to sexually transmitted infections. The objective of this study was to estimate the prevalence of Chlamydia trachomatis infection among general population women in Doha, Qatar. Methods Endocervical swabs were collected from healthy women attending primary healthcare centres in Doha, June–December 2008. The specimens were tested for C trachomatis by a commercially available PCR-based assay. Data on basic socio-demographic characteristics, medical history and sexual behaviour were obtained using self-administered questionnaires. The prevalence of C trachomatis and of background variables were stratified by nationality, Qatari nationals versus non-Qatari residents. Results A total of 377 women were enrolled in the study, out of whom 351 (37.9% Qataris, 62.1% non-Qataris) were tested for the presence of C trachomatis in their specimens. The mean age of participants was 41.2 years, and the vast majority (93%, 95% CI 90.3 to 95.7) were married. The mean age at sexual debut was significantly lower among Qatari women compared with non-Qatari women (19.2 vs 22.2 years, respectively p<0.001), but the mean number of reported lifetime sexual partners (1.1 partner) was nearly the same in both groups (p=0.110). The prevalence of C trachomatis infection was 5.3% among Qatari women and 5.5% among non-Qatari women, with no statistically significant difference between both groups (p=0.923). Conclusions The prevalence of C trachomatis among women was higher than expected, with no significant difference between Qatari nationals and expatriate residents. The higher prevalence may reflect, in part, the limited access to and use of chlamydia screening and management.

The utility of a single glucometer measurement of fasting capillary blood glucose in the prevalence determination of diabetes mellitus in an urban adult Palestinian population.

This paper aims to evaluate the utility of a single glucometer fasting capillary blood glucose (FCBG) measurement in determining the prevalence of diabetes mellitus in a homogeneous adult population. FCBG measurements were compared with results of the oral glucose tolerance test (OGTT) in 445 subjects aged 30-65 years in an urban cross-sectional study in Old Ramallah. Prevalence of diabetes, sensitivity, specificity and predictive values were calculated at different cut-off levels of FCBG, using OGTT as the reference. The prevalence of OGTT-diagnosed diabetes was 2.7%, while it varied considerably using different cut-off levels of FCBG. The sensitivity of a single glucometer (Exac Tech II) measurement of FCBG at the cut-off level of 6.7 mmol l-1 was 33.3%, with a specificity of 98.8%. Using the cut-off level of 6.1 mmol l-1 as suggested by the 1998 provisional report of a WHO consultation, the sensitivity increased to 41.7%. At a cut-off level of 5.6 mmol l-1, a sensitivity of 66.6% was reached, but the specificity decreased slightly. It can be concluded that a single glucometer measurement of FCBG in an adult population is not useful in determining the prevalence of diabetes mellitus.This paper aims to evaluate the utility of a single glucometer fasting capillary blood glucose (FCBG) measurement in determining the prevalence of diabetes mellitus in a homogeneous adult population.
