To provide updated prevalence data of BMI and obesity in 4-year-old Swedish children, also exploring socioeconomic differences.
A total of 4407 children born 1998-1999 (2231 boys and 2176 girls) in the county of Västerbotten, Sweden.
Overweight and obesity was estimated using the International Obesity Task Force cutoff values (ISO BMI). Information about socioeconomic level of the municipalities was collected from a health survey of the adult population.
Of the boys, 16.7% were classified as overweight and 3.1% of these as obese. Corresponding figures for girls were 22.1% and 6%. [corrected] The P50 and P95 values for BMI were 16.2 and 18.8 for boys and 16.1 and 19.3 for girls, respectively. P50 was at the same level as in previous Swedish studies, while P95 was higher in this study. Obesity, in girls, was more prevalent in municipalities with a low socioeconomic level.
Overweight and obesity in pre-school children in Sweden is more prevalent in girls than in boys, and the prevalence is as high as in school age children. A low socioeconomic level of living area seems to be related to a higher prevalence of obesity. Increased preventive efforts, both on the individual and the societal level, must be undertaken to reduce future health risks in obese children.
提供瑞典4岁儿童体重指数（BMI）和肥胖症的最新流行数据，并探讨社会经济差异。
瑞典韦斯特博滕郡1998 - 1999年出生的4407名儿童（2231名男孩和2176名女孩）。
采用国际肥胖特别工作组的临界值（ISO BMI）评估超重和肥胖情况。从一项针对成年人口的健康调查中收集有关各市社会经济水平的信息。
男孩中，16.7%被归类为超重，其中3.1%为肥胖。女孩的相应数字分别为22.1%和6%。[已修正]男孩BMI的P50和P95值分别为16.2和18.8，女孩分别为16.1和19.3。P50与瑞典此前的研究处于同一水平，而本研究中的P95更高。在社会经济水平较低的市镇，女孩肥胖更为普遍。
瑞典学龄前儿童超重和肥胖在女孩中比在男孩中更普遍，且患病率与学龄儿童一样高。生活地区社会经济水平较低似乎与肥胖患病率较高有关。必须在个人和社会层面加大预防力度，以降低肥胖儿童未来的健康风险。
