Lee: The Factors Influencing the Bone Mineral Density in Korean Adult Men : Based on Korea National Health and Nutrition Examination Survey 2010~2011 Data

Abstract

Objectives

The purpose of this study was to determine which factors influence the bone mineral density (BMD) of total femur (TF), femoral neck (FN) and lumbar spine (LS) of the adult men by analyzing nationally representative Korean survey data.

Methods

This study was conducted based on the data of 1,770 men aged 19-64 years from the Fifth Korea National Health and Nutrition Examination Survey (KNHANES V), 2010~2011. The BMD was analyzed by various factors (general characteristics, anthropometric data, health habits, chronic diseases, nutrient intake status). SPSS statistics for complex samples was used to analyze the data.

Results

We observed that the BMD decreased significantly with aging. The BMD in each of the second lowest quartile of waist circumference (in TF & FN) and body mass index (in TF & LS) was lower than the respective BMD in the highest quartile group. The BMD in FN was higher in the group who reported the weight training. The BMD in LS was lower in hypercholesterolemia group than in the normal group. The BMD in TF, FN and LS was lower in hypertriglyceridemia group and in diabetes group than in the normal group. The BMD in TF, FN and LS was higher in the group with < Estimated Average Requirement iron intake. But there was no evidence to suggest that the BMD was related with educational level, income level, smoking, alcohol intake, anemia and nutrient intake status (except for iron).

Conclusions

This study suggested that aging, waist circumference, body mass index, weight training, hypercholesterolemia, hypertriglycemia, diabetes were site-specifically associated with the BMD in TF, FN and LS in the adult men. These bone site-specific factors need to be considered for the prevention of osteoporosis.
