Measurement of neck circumference (NC) is an easy method to assess obesity. Our investigation to estimate risks for metabolic disease in Japanese postmenopausal women indicated that NC is significantly associated with whole-body obesity indices and visceral fat accumulation. To clarify the early stage of metabolic changes and confirm NC validity as a predictor of metabolic syndrome, NC’s association to the four obesity indices, namely, weight, body mass index (BMI), body fat, and waist circumference (WC), was examined in a college student group of 60 females aged 18.7±0.3 years. NC was mainly correlated with weight, followed by BMI, WC, and body fat. It was also significantly associated with weight and BMI, but not with body fat. The participants were divided into two subgroups: “sports-experienced” and “not-sports-experienced,” who had moderate and strong correlation coefficients with NC and WC, respectively. WC value was possibly predicted by NC values using linear functions for t...

Infrared thermography provides a non-invasive and dynamic measure of heat. The thermal preservability effects of a salt footbath were evaluated by the infrared thermography technique. The subjects were 23 healthy college students. Feet were soaked for 10 min in a 40-42 degrees C normal footbath. Room temperature was set at 26.5-28 degrees C. At the same time on another day within 3 days of the normal footbath experiment, the same feet were soaked for 10 min in a 40-42 degrees C salt footbath. We measured blood pressure, heart rate and temperatures of the feet, second toes, hands and middle fingers, just before and after immersion and at 10-min intervals thereafter. Mean blood pressure changes showed no difference between the normal and the salt footbath. Mean heart rate changes were higher during the normal footbath than at 0, 15 and 20 min during the salt footbath, respectively (p < 0.05). Mean thermal preservability of the feet tended to be lower after the normal footbath than ...

Subcutaneous fat depots play an important role in regulating metabolic profile in Japanese postmenopausal women. We investigated the possibility of neck circumference (NC) as a surrogate marker for metabolic disease risk estimates in Japanese postmenopausal women. We examined the association of NC with several markers of insulin resistance, lipid metabolism and atherosclerosis in 64 healthy postmenopausal women aged 63.6 ± 7.1 years in community-based samples in Japan. As a result, NC was significantly associated with indices of whole body obesity and visceral fat accumulation, such as body mass index (BMI) and Waist circumference (WC). In the analysis of biomarkers for insulin resistance, NC was positively correlated to HbA1c, homeostasis model assessment ratio (HOMA-R) and leptin. In addition, an increase in triglycerides (TG) and a decrease in HDL-cholesterol (HDL-C) were also associated with NC. Interestingly, NC was also associated with atherosclerosis-related indices. The meas...

The relationship of bone mineral density (BMD) and bone metabolic markers in women is an interesting field of research. In this study, we aimed to clarify the relationship of body weight, bone metabolic markers and BMD. The subjects were 72 women. The levels of serum bone-specific alkaline phosphatase (BAP), serum type I collagen-cross-linked peptide (s-NTx) and urinary deoxypyridinoline (u-DPD) were measured. The associations between dependent variables (BMD changes/1 or 4 years in the lumbar spine and femoral neck) and explanatory variables (body weight changes/1 or 4 years, the levels of BAP, s-NTx, u-DPD) were evaluated using multiple regression analysis. Changes in the lumbar spine BMD were significantly correlated with changes in height over a year, and those of the femoral neck were significantly correlated with changes in weight over a year. Changes in the lumbar spine BMD over 4 years were significantly correlated with age, BAP and the changes of weight over 4 years. Change...
