Abstract

Earlier age at menarche is one of the well-documented antecedents of a range of adverse health effects in adulthood including obesity and psychopathological effects. Yet, few researchers have examined the potential association of menarcheal age with body fat distribution, self-perception, and body image. We retrospectively tested a sample (N = 392) of adult women (18-80 years) to examine the associations of age at menarche with body composition and body image indices. Analyses of covariance and multivariable logistic and linear regression were fitted adjusting for age, physical activity level, smoking, and alcohol consumption. Further adjustment was made for body mass index (BMI) and percentage of fat mass. Earlier age at menarche was associated with slightly increased odds of higher BMI and abdominal fat percentage; of note is the positive correlation with lower body composition indices including hip and calf circumferences/skinfolds. Additionally, earlier age at menarche was associated with higher scores in the negative body image scales, namely overweight preoccupation and self-classified weight, whereas lower risks were found for higher scores in the positive body image scales, namely appearance evaluation and body area satisfaction scales. These findings remained significant after correcting for body fat percentage. The present results showed positive associations for earlier age at menarche with gross indices of obesity with the associations mainly confined to distribution of body fat in the lower part of the body, whereas an increased risk of negative body image was also found. Future research could refine our understanding of the biological and psychological mechanisms underlying these associations.

初潮年龄较早与成年后体脂和负面身体形象有关。
初潮年龄的提前是成年期一系列不良健康影响的前兆之一,包括肥胖和精神病理影响。然而,很少有研究人员研究过月经初潮年龄与身体脂肪分布、自我认知和身体形象之间的潜在联系。我们回顾性测试了392名成年女性(18-80岁)的样本,以研究初潮年龄与身体组成和身体形象指数的关系。对年龄、体力活动水平、吸烟和饮酒进行协方差分析、多变量逻辑回归和线性回归校正。进一步调整身体质量指数(BMI)和脂肪质量百分比。初潮年龄越早,BMI和腹部脂肪率升高的几率也越高;值得注意的是,它与包括臀部和小腿围/皮肤褶皱在内的下半身组成指数呈正相关。此外,初潮年龄越早,在负面身体形象量表(即超重关注和自我分类体重)中得分越高,而在正面身体形象量表(即外貌评价和身体面积满意度量表)中得分越高,风险越低。在校正体脂百分比后,这些发现仍然很重要。目前的研究结果显示,初潮年龄越早与肥胖总体指数呈正相关,且这种关联主要局限于身体下部的体脂分布,而负面身体形象的风险也会增加。未来的研究可以完善我们对这些关联背后的生物学和心理学机制的理解。

期刊介绍: Behavioral Medicine is a multidisciplinary peer-reviewed journal, which fosters and promotes the exchange of knowledge and the advancement of theory in the field of behavioral medicine, including but not limited to understandings of disease prevention, health promotion, health disparities, identification of health risk factors, and interventions designed to reduce health risks, ameliorate health disparities, enhancing all aspects of health. The journal seeks to advance knowledge and theory in these domains in all segments of the population and across the lifespan, in local, national, and global contexts, and with an emphasis on the synergies that exist between biological, psychological, psychosocial, and structural factors as they related to these areas of study and across health states. Behavioral Medicine publishes original empirical studies (experimental and observational research studies, quantitative and qualitative studies, evaluation studies) as well as clinical/case studies. The journal also publishes review articles, which provide systematic evaluations of the literature and propose alternative and innovative theoretical paradigms, as well as brief reports and responses to articles previously published in Behavioral Medicine.
