Acne vulgaris is a common skin disease of adolescents. One risk factor for the development of acne is a high body mass indices. Children with high body mass index are said to be more likely to have increased Insulin-like growth factor-1, which has been implicated in acne pathogenesis. The aim of this study was to correlate body mass index with the presence and severity of facial acne vulgaris in adolescent school children.
This was a cross-sectional study in four co-educational secondary schools in Ibadan, Nigeria. One thousand and seventy nine students aged 9-20 years were physically assessed for facial acne vulgaris and their heights (m2) and weights (kg) were measured for body mass index (kg/m2) estimation. The severity of acne was assessed using the comprehensive acne severity scale. Data was analyzed using the SPSS 16.
The prevalence of facial acne vulgaris was 53.2%. The age of the students ranged from 9-20 years. The mean body mass index (BMI) for the students with acne was 19.9±3.3kg/m2 and 18.3 ± 3.11 kg/m2 for students without acne, P<0.0001. The prevalence of acne was 81.7% among adolescents with a BMI >25Kg/m2, 61.1% in those with a BMI of 18.5-24.99 kg/m2 and 42.0% among adolescents with a BMI of <18.5 Kg/m2, P<0.001 but BMI was not significantly associated with severity of acne (p=0.830).
Adolescents with a high body mass index are more likely to have facial acne vulgaris but severity of acne is independent of body mass index.
寻常痤疮是青少年常见的皮肤病。痤疮发生的一个风险因素是高体重指数。据说体重指数高的儿童更有可能具有升高的胰岛素样生长因子-1，这与痤疮发病机制有关。本研究的目的是将体重指数与青少年在校儿童面部寻常痤疮的存在及严重程度相关联。
这是一项在尼日利亚伊巴丹四所男女同校中学进行的横断面研究。对1079名9至20岁的学生进行了面部寻常痤疮的体格检查，并测量了他们的身高（平方米）和体重（千克）以估算体重指数（千克/平方米）。使用综合痤疮严重程度量表评估痤疮的严重程度。数据使用SPSS 16进行分析。
面部寻常痤疮的患病率为53.2%。学生年龄范围为9至20岁。患痤疮学生的平均体重指数（BMI）为19.9±3.3千克/平方米，未患痤疮学生的平均体重指数为18.3±3.11千克/平方米，P<0.0001。体重指数>25千克/平方米的青少年中痤疮患病率为81.7%，体重指数为18.5 - 24.99千克/平方米的青少年中为61.1%，体重指数<18.5千克/平方米的青少年中为42.0%，P<0.001，但体重指数与痤疮严重程度无显著相关性（p = 0.830）。
体重指数高的青少年更有可能患面部寻常痤疮，但痤疮严重程度与体重指数无关。
