【摘要】 目的探讨女童单纯乳房早发育的危险因素。方法选取7～8岁(不含8岁)单纯乳房早发育女童150例作为观察组,另取150例健康女童作为对照组。比较两组一般情况、家庭情况、饮食和行为生活情况、体质指数(BMI),分析女童单纯乳房早发育的危险因素。结果两组女童的母亲月经初潮年龄、食用鸡鸭肉和方便食品情况、看电视时间、每晚睡觉时间及BMI比较,差异均具有统计学意义(均P <0. 05)。多因素Logistic回归分析结果显示,方便食品进食过多、看电视时间长、睡眠时间晚和BMI高是单纯性乳房早发育的危险因素(均P <0. 05)。结论进食方便食品多、看电视时间长、睡眠时间晚和BMI高的女童发生单纯乳房早发育的风险增高。更多还原

【Abstract】 Objective To explore the risk factors for isolated premature thelarche in girls. Methods A total of 150 girls with isolated premature thelarche aged 7 to 8 years( excluding the age of 8 years) were selected as observation group,and another 150 healthy girls of the same age were enrolled as control group. The data of general information,family,diet,behavior and life style as well as body mass index( BMI) were compared between the two groups,and the risk factors for isolated premature thelarche were analyzed in girls.Results There were statistically significant differences in the age of mother’s menarche,consumption of chicken,duck and convenience food,duration of watching TV,sleeping duration per night,and BMI between the two groups( all P < 0. 05). The results of multivariate Logistic regression analysis showed that eating too much convenience food,watching TV for long hours,sleeping late,and elevated BMI were risk factors for isolated premature thelarche( all P < 0. 05). Conclusion The elevated risk of isolated premature thelarche is seen in girls who prefer to eat convenience food,watch TV for long hours,sleep late or have a high BMI.更多还原
