We assessed the 15-year trends in the distribution of body mass index (BMI) and the prevalence of overweight in the Seychelles (Indian Ocean, African Region) and the relationship with socio-economic status (SES). Three population-based examination surveys were conducted in 1989, 1994 and 2004. Occupation was categorized as 'labourer', 'intermediate' or 'professional'. Education was also assessed in 1994 and 2004. Between 1989 and 2004, mean BMI increased markedly in all sex and age categories (overall: 0.16 kg m(-2) per calendar year, which corresponds to 0.46 kg per calendar year). The prevalence of overweight (including obesity, BMI >or= 25 kg m(-2)) increased from 29% to 52% in men and from 50% to 67% in women. The prevalence of obesity (BMI >or= 30 kg m(-2)) increased from 4% to 15% in men and from 23% to 34% in women. Overweight was associated inversely with occupation in women and directly in men in all surveys. In multivariate analysis, overweight was associated similarly (direction and magnitude) to occupation and education. In conclusion, the increasing prevalence of overweight and obesity over time in all age, sex and SES categories suggests large-scale changes in societal obesogenic factors. The sex-specific association of SES with overweight suggests that prevention measures should be tailored accordingly.
我们评估了塞舌尔（印度洋，非洲地区）体重指数（BMI）分布和超重患病率的15年趋势，以及与社会经济地位（SES）的关系。1989年、1994年和2004年进行了三项基于人群的检查调查。职业分为“劳动者”、“中级”或“专业人员”。1994年和2004年也对教育程度进行了评估。1989年至2004年期间，所有性别和年龄组的平均BMI均显著增加（总体：每年0.16kg/m²，相当于每年0.46kg）。男性超重（包括肥胖，BMI≥25kg/m²）患病率从29%增至52%，女性从50%增至67%。肥胖（BMI≥30kg/m²）患病率男性从4%增至15%，女性从23%增至34%。在所有调查中，女性超重与职业呈负相关，男性呈正相关。在多变量分析中，超重与职业和教育的关联相似（方向和幅度）。总之，所有年龄、性别和社会经济地位类别中超重和肥胖患病率随时间增加，表明社会致肥胖因素发生了大规模变化。社会经济地位与超重的性别特异性关联表明，预防措施应相应调整。
