Abstract

Understanding body size growth pattern is one of the best ways to find out biological variation in phenotypic plasticity, health and nutritional statuses, and quality of life. Optimum environment and better nutrition are associated with rapid growth, tall stature, and early puberty. However, poor living condition impacts every stage of development, which results in variation in growth rates, growth periods, and body sizes across populations. Baduy is one of traditional populations who inhabit mountainous area in Kanekes Village, Lebak Regency, Banten Province, Indonesia. The traditional obligatory duties and taboos resulted in genetic, geographic, and cultural isolations. This leads to question whether the biocultural condition affects the growth pattern of their body size. We measured the body height, weight, and mass index of 340 girls and 239 boys aged 4–30 years sampled from 39 of 61 hamlets using cross-sectional method. We found that Baduy people had prolonged growth resulting in small body size because of slow rate and low spurt. This might be a selection to save body maintenance costs in biocultural condition with poor nutrition and high physical activity.

Abstract

Several small-scale populations exhibited phenotypic plasticity whereby growth spurt of body height occurred much earlier than age at menarche and this was not followed by same early spurt of body weight. This leads to question whether growth trajectory of stature follow the same growth trajectory of body mass and whether the trajectory itself is associated to sexual maturity. We evaluated developmental plasticity observed in Baduy girl, a traditional population in Indonesia, in facing strenuous environmental and biocultural conditions. We measured stature and body mass cross-sectionally. We determined age at menarche as population average of age of girls that had already got their first menstruation. Growths of body fat and weight followed a same mode and timing and their spurts pivoted on the age at menarche. In contrast, growth spurt of body height occurred four years earlier than menarche and velocity curve of body linearity progressed in opposite direction to that of body ponderality. The prevailing poor nutrition and high physical activity elicited principle of ontogenetic allometry to synchronize the acceleration and deceleration of growths in body linearity and ponderality whereby growth in body height functions to reach the body size target and to provide skeletal framework for development of body mass. The biocultural conditions lead to slow bodily growth rate with low spurt resulting in the characteristics of Baduy girl that was small in size and late in both sexual maturity and full-grown ages.

Abstract

Menopause is the permanent cessation of menstruation due to loss of ovarian follicular activity. Assessment of the age of menopause is particularly important because previous studies have shown a high risk of osteoporosis, hypertension, stroke, and coronary heart disease. This study aims to determine the risk factors for early menopause in Javanese women in Oransbari District, West Papua Province. The cross-sectional sampling method was carried out on women aged 51.73 years with an interval of 40.07-78.58 years. Age at menopause was calculated using the Probit Generalized Linear Model (GLM) analysis. We used a binary logit regression (BLR) model to estimate risk factors for early menopause. BLR analysis was fitted to estimate the odds ratio (OR) and 95% confidence interval (CI). Age at menopause is divided into two categories, normal (≥45 years) and early (<45 years). Our results show that the average age of menopause is 43.1 years, or the early menopause category, with an age range of 39.61 to 55.28 years. The results of the partial parameter significance test at the 10% significance level showed that no formal education (OR: 2.348; CI 1.4213.917) had the most significant risk factor for experiencing early menopause, followed by parity (OR: 0.623; CI: 0.377-1.023), contraception (OR: 0.118; CI: 0.038-0.296), and the lowest risk was the age at first delivery (OR: 0.389; CI: 0.207-0.716). The biocultural conditions experienced early in life in Oransbari shape the character of a younger reproductive age as an adaptive response to maximize fitness.
