背景资料：初潮的早期发病与肥胖的患病率，但是，这可能会有所不同的土著feminals.Objective：分析初潮的年龄和营养状况之间的关系土著和非土著girls.Method：本研究的设计是横截面。月经初潮的日期是通过访谈确定的，所有的回答都得到了女孩母亲的证实。共有8504名青少年最近月经初潮筛查。一百三十一名女孩的马普切（土著）和143名女孩的智利，西班牙的背景进行了鉴定和评估的人体测量measurements.Results：初潮的中位年龄为150个月，四分位距（IR）143-157在土著，和145.5个月，IR 139-153在非土著女孩（P = 0.04）。土著妇女超重的发生率较高（36.4%对23.1%），但肥胖的发生率相似（16.8%对16.3%）。土著女孩的初潮年龄推迟了2.69个月（置信区间为0.38至5.77）。结果发现，超重女孩的初潮年龄比正常体重女孩早7.59个月，可信区间为-10.78 ~-4.41。肥胖对月经初潮年龄的影响相似，均比正常体重组提前7.53个月，CI为-11.34 ~-3.72。结论：超重和肥胖女孩月经初潮年龄较以往报道的偏小，且偏早，与是否为土著无关。
Background: Early onset of menarche has been linked to prevalence of obesity; however, this may differ for indigenous females.Objective: To analyse the relationship between age of menarche and nutritional status among indigenous and non-indigenous girls.Method: The design of this study was cross-sectional. Date of menarche was determined through interviews, and all responses were confirmed by the girls' mothers. A total of 8504 adolescents were screened for recent menarche. One hundred and thirty-one girls of Mapuche (indigenous) and 143 girls of Chilean-Spanish background were identified and evaluated by anthropometric measurements.Results: Median age of menarche was 150 months, interquartile range (IR) 143-157 in indigenous, and 145.5 months, IR 139-153 in non-indigenous girls (p = 0.04). The indigenous females showed a higher prevalence of overweight (36.4% vs 23.1%), although the frequency of obesity was similar (16.8% vs 16.3%). For indigenous girls, age of menarche was delayed by 2.69 months (confidence intervals (CI) - 0.38 to 5.77). It was observed that girls with overweight experienced age of menarche 7.59 months earlier than those with normal weight, CI -10.78 to -4.41. In the analysis of obesity, the effect on age of menarche was similar, with onset 7.53 months earlier than for the normal weight, CI -11.34 to -3.72.Conclusion: Age of menarche is younger than has been previously reported and occurs earlier in girls with overweight and obesity, while being indigenous was not related.
