Weight-bearing physical activity, calcium intake, systemic glucocorticoids, chronic inflammation, and body constitution as determinants of lumbar and femoral bone mineral in juvenile chronic arthritis.

The associations between the lumbar and femoral bone mineral and several body constitutional, lifestyle, and disease related variables were studied in 111 children with juvenile chronic arthritis (JCA) by factor and multiple linear regression analyses. In addition to the measurement of bone mineral density (BMD), bone width and bone mineral volumetric density (BMDvol) were determined by dual-x-ray absorptiometry (DXA). Factor analysis of 13 explanatory variables yielded six non-correlating factors, named as body size, physical activity, calcium intake, glucocorticoids, disease duration, and disease activity. These six factors were used as new variables to explain BMD, BMDvol, and bone width by multiple linear regression analyses. These showed body size, physical activity, and calcium intake as significant positive and disease activity and glucocorticoids as significant negative determinants of BMD in JCA. The analyses revealed also considerable differences in the relationships between factors and BM Dvol or bone width.

Breast size in relation to endogenous hormone levels, body constitution, and oral contraceptive use in healthy nulligravid women aged 19-25 years.

In 1993 and 1994, the relation between breast size and hormonal factors and body constitution was studied in 65 healthy nulligravid women aged 19-25 years. Twenty-five women were current oral contraceptive users, 20 women were former users, and 20 women had never used oral contraceptives. Breast size was strongly positively correlated with current oral contraceptive use during menstrual cycle days 5-10, as well as days 18-23. No significant effect of former oral contraceptive use was seen on breast size. A significant increase in breast size between cycle days 5-10 and days 18-23 was seen among current oral contraceptive users. Breast size was significantly positively correlated with body mass index (weight (kg)/height (m)2), height, and weight in nonusers (i.e., former and never users combined) but not in current users. In nonusers, during the follicular phase, breast size was significantly positively associated with insulin-like growth factor 1. During the luteal phase, larger breast sizes were significantly associated with higher 17 beta-estradiol and progesterone levels and lower testosterone levels among nonusers. In models for current users, large breast sizes were significantly associated with high prolactin and luteinizing hormone levels and low follicle-stimulating hormone levels during cycle days 5-10. During cycle days 18-23, larger breast sizes correlated with low endogenous progesterone levels.
