The present study was initiated to derive an indirect method for estimating body fat mass (BFM) and to evaluate the correlation between indirect anthropometric techniques for this estimation and to examine the relation of these parameters and of IQ to age of menarche. A total of 578 adolescent girls of ten junior high schools in five educational districts of Mashhad, participated in a cros...

The age women reach menarche may affect bone length and mass. Some studies show an earlier menarcheal age (MA) results in a shorter stature and increased body fat. We hypothesized that Hutterite women have a shorter height and limb length, but greater bone mass and areal bone mineral density (aBMD) than non-Hutterites. Results are from a secondary analysis of 344 (198 Hutterite) healthy, pre-me...

The aim of this paper is to analyse age at menarche in Tanzanian girls for associations with body composition and selected somatic indices. The study included 97 girls (71 post-menarche and 26 pre-menarche). Measurements were taken of body height, body weight, waist and hip circumferences. Body composition was analysed for percentages of body H2O, fat, and muscle. The girls' nutritional status ...

We used data from a cross-sectional study of 107 premenopausal women to evaluate the relation of age, menarcheal age, parity, and age at first live birth with plasma estrogen and androgen levels in premenopausal women. Fasting blood specimens were collected on each of days 5-7, 12-15, and 21-23 of menstrual cycles of the participants and pooled to create follicular, midcycle, and luteal phase s...

This case-control study evaluated reproductive and other factors in relation to epithelial ovarian cancer (EOC) risk. Between 1993 and 1995, the authors recruited 655 EOC cases and 3,899 population controls aged 50-74 years who were born in and residents of Sweden. Data were collected through mailed questionnaires. Odds ratios were estimated by unconditional logistic regression. Parity reduced ...

BACKGROUND The study of the correlation of menopausal symptoms with heart rate variability (HRV) has not been adequate. The aim of this study was to investigate the relationship between postmenopausal symptoms measured by the menopause rating scale (MRS) and HRV. METHODS We assessed postmenopausal symptoms (using MRS) with age, BMI, educational status, occupation, marital status, alcohol and ...

Intrauterine exposure to the rainy season in the tropics may be accompanied by high rates of infection and nutritional deficiencies. It is unknown whether this exposure is related to the extrauterine timing of development. Our aim was to evaluate the relations of prenatal exposure to the rainy season and altitude of residence with age at menarche. The study included 15,370 girls 10 to <18 years...
