ABSTRACT
High body mass index [BMI] is an important risk factor for morbidity and mortality, while low BMI is an indicator of undernutrition; both may be concerns in low-income countries. This cross-sectional, primary-care based study aimed to measure the sex and age-specific mean BMI and estimate the prevalence of obesity, overweight and underweight among adults in an urban community in Sana'a, Yemen. A total of 2500 subjects [919 males and 1581 females] were recruited in 2006. The crude mean BMI for all ages was significantly higher in females [23.9 [SD 5.1] kg/m2] than males [21.8 [SD 8.9] kg/m2]. The mean BMI trend was associated with age, with a peak in the age group 35-44 years. Calculated prevalence showed 18.0% of males and 14.6% of females were overweight [BMI >/=25 kg/m2] and 2.5% of males and 12.4% of females were obese [BMI >/=0 kg/m2]. In contrast a substantial number of subjects were underweight [BMI < 18.5 kg/m2]: 20.1% of males and 14.6% of females

We assessed the causes of visual impairment and blindness in 694 diabetic patients attending our eye centre in Sana'a, Yemen from 2001 to 2005 by review of their medical records. The mean age of the patients was 53.9 [SD 11.52] years, range 13-95 years, and 382 [55%] were males. According to the World Health Organization definitions, 273 [39.3%] patients had visual impairment and 109 [15.7%] were blind. Cataract, proliferative diabetic retinopathy [PDR] and diabetic maculopathy were the main causes of visual impairment and blindness. Patients with PDR and maculopathy were significantly more likely to have visual impairment compared to patients without retinopathy [RR = 1.99, 95% CI: 1.74-2.28 and RR - 1.84, [95% Cl: 1.60-2.13 respectively] and be blind [RR - 4.69, 95% Cl: 3.70-5.95% and RR= 2.53, 95% CI: 1.92-3.34 respectively]. Diabetic retinopathy is a public health problem in Yemen and national screening and educational programmes are highly needed to reduce the risk of visual impairment and blindness among diabetics

The study determined the prevalence of type 2 diabetes, abnormal glucose tolerance and other cardiovascular risk factors in a sample of 250 adults aged >/= 35 years in a semirural area near Sana'a, the capital of Yemen. The overall crude prevalence of diabetes was 10.4% [95% CI: 6.6%-14.2%] and the age-standardized rate was 6.3% [95% CI: 5.4%-7.2%]. The age-standardized rate of having either impaired fasting glucose or impaired glucose tolerance was 9.0% [95% CI: 6.0%-12.0%] and the age-standardized prevalence of hypertension was 14.2% [95% CI: 13.0%-16.0%]. Age and waist circumference were independently related to total glucose intolerance. The observed high frequency of central obesity suggests a dietary origin for these adverse health conditions

Catha edulis Forsk leaves [khat] are chewed daily by a high proportion of the adult population in Yemen for the mild stimulant effect. Cathinone is believed to be the main active ingredient in fresh khat leaves and is structurally related and pharmacologically similar to amphetamine. The habit of khat chewing is widespread with a deep-rooted sociocultural tradition in Yemen and as such poses a public health problem. The objective of this literature review was to examine studies on khat, particularly human studies, with special reference to its effect on the central nervous system, cardiovascular, digestive and genitourinary systems, oral-dental tissues, diabetes mellitus and cancer

The present study was undertaken to determine the prevalence of known cases of diabetes and hypertension among adults in Sana'a city. Thus 1080 persons aged 20-85 years were selected for interview using a multistage random sampling technique. The crude prevalence of known diabetes was 6.57% [95% CI: 5.2-8.2] and of known hypertension 13.5% [95% CI: 11.5-15.6]. The age standardized prevalence for the age range 30-64 years was 9.75% [95% CI: 7.5511.95] for diabetes and 17.1% [95% CI: 15.0-19.2] for hypertension. These results provide an estimate of the prevalence of known diabetes, hypertension and related vascular events in a well-defined urban community
