To determine the prevalence of obesity in Ghanaian adults.
6300 adults, aged 25 years and older, were selected by random cluster sampling using electoral enumeration areas and listings of adults.
Two urban and one rural community in the Greater Accra region of Ghana.
4733 (males=1860, females=2873) adult Ghanaians participated. Height and weight were determined for subjects wearing light clothing and without shoes.
The mean age and BMI were 44.3 years and 24.4 kg/m2, respectively. Women, though younger, had higher BMI values compared to males (25.6 vs 22.6 kg/m2, respectively; P<.001). The overall crude prevalence of overweight (25.0-29.9 kg/m2) and obesity (> or = 30 kg/m2) were 23.4% and 14.1% for females and males, respectively. The rates of overweight (27.1% vs 17.5%) and obesity (20.2% vs 4.6%) were both higher in women than men. The age-standardized prevalence of obesity in Ghanaians was 13.6%. Obesity increased with age, peaking in the 55-64-year age group. The first to fourth BMI quartiles were: < or = 20.6, 20.7-23.3, 23.4-27.2, and > or = 27.3 kg/m2, respectively. At all ages, more females (32.9%) than males (12%) were placed within the 4th BMI quartile. Residents from the high-class residential area had higher BMI, compared to subjects from the lower class suburb. Also, urban residents had higher BMI compared to rural subjects.
Overweight and obesity are common in Ghanaians, particularly among females, the elderly, and urban dwellers. Further work is needed to ascertain the determinants of overweight and obesity in Ghanaians.
确定加纳成年人肥胖症的患病率。
采用随机整群抽样方法，利用选举枚举区和成年人名单，选取6300名年龄在25岁及以上的成年人。
加纳大阿克拉地区的两个城市社区和一个农村社区。
4733名加纳成年人均参与了研究（男性1860名，女性2873名）。测量了研究对象在穿着轻便衣物且不穿鞋时的身高和体重。
平均年龄和体重指数分别为44.3岁和24.4kg/m²。女性尽管年龄较小，但体重指数高于男性（分别为25.6和22.6kg/m²；P<0.001）。女性超重（25.0-29.9kg/m²）和肥胖（≥30kg/m²）的总体粗患病率分别为23.4%和14.1%，男性超重（27.1%对17.5%）和肥胖（20.2%对4.6%）的患病率均高于男性。加纳人肥胖症的年龄标准化患病率为13.6%。肥胖症患病率随年龄增长而升高，在55-64岁年龄组达到峰值。体重指数的第一至第四四分位数分别为：≤20.6、20.7-23.3、23.4-27.2和≥27.3kg/m²。在所有年龄段，处于第四体重指数四分位数的女性（32.9%）多于男性（12%）。与来自低收入郊区的研究对象相比，来自高档住宅区的居民体重指数更高。此外，城市居民的体重指数高于农村居民。
超重和肥胖症在加纳人中很常见，尤其是在女性、老年人和城市居民中。需要进一步开展工作以确定加纳人超重和肥胖症的决定因素。
