This study explored the relationship of maternal body composition parameters to the birth weight of the offspring. Maternal anthropometric parameters (weight, height) and body composition by dual energy X-ray absorptiometry were measured in 76 women from low-income group during 12-21 days postpartum. The mean+/-s.d. height, weight of the mothers and birth weight of the newborns were 151.5+/-5.29 cm, 46.7+/-6.04 and 2.84+/-0.358 kg, respectively. When the relationship of maternal anthropometric and body composition parameters to the infants' birth weight was studied, maternal lean body mass was found to be the most important determinant of birth weight (R2 (%) = 21.3) (P < 0.001). This study highlights the importance of increasing lean body mass in young women for better pregnancy outcome.

Regression Toward the Mean

Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when researchers try to extrapolate results...

Obesity

The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in adipocytes...

Nature and Nurture

Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience, such as differences...
