Body weight was self-reported whereas information on body height was obtained from measurements performed at the baseline examinations.
Demographic characteristics (age, sex, occupation, body weight, height) were obtained from the patient records.
To calculate individual values for BMC at each skeletal site after adjustment for bone and body size (SA-BMC), the residuals from loge-loge regression models of BMC with BA, body weight, and height were obtained and added to mean loge(BMC), and the antilogarithm was obtained.
Self-reported body weight and height were obtained from participants in the depression group via the SCAN interview and from the healthy control group via telephone interview.
Body weight and height were obtained through a health examination (n = 6068, participation rate 88%) at the age of 15 to 16 years, and these were converted into body mass index (BMI), which was calculated as weight (kg) divided by height squared (m).
Living arrangements (living with others or living alone), educational attainment (years of education), employment status (working hours per week), self-rated health, dog ownership (having a dog, or not), driving status (driver, or non-driver), MVPA (minutes per week), body weight and height were obtained through self-report by each respondent.
Body weight and standing height were obtained in the morning of Day 1 and were used to calculate body mass index (BMI) as weight (kg)/height (m).
Body mass index (BMI; weight / height) was obtained through height and weight measurements by using a wall-mounted ruler and a digital scale.
Body mass was measured to the nearest 0.1 kg on a calibrated scale (SECA, Hamburg, Germany), and height was obtained with a standard stadiometer (Takei, Tokyo, Japan).
Body weight was measured to the nearest 0.2 kg on a calibrated balance (Seca 707; Seca, Hamburg, Germany) and height was obtained with a standard stadiometer (Takei Scientific Instruments Co Ltd, Tokyo, Japan).
