Fruit intake and osteosarcopenic obesity in Korean postmenopausal women aged 50-64 years.

OBJECTIVES

The purpose of this study was to assess the association between fruit intake and abnormalities in body composition (bone, muscle, and adipose tissue) related to osteosarcopenic obesity (OSO) in postmenopausal women.

STUDY DESIGN

The data of 1420 postmenopausal women aged 50-64 years were collected from cross-sectional studies conducted by the Korea National Health and Nutrition Examination Survey (KNHANES) from 2008 to 2010.

MAIN OUTCOME MEASURES

A dietary intake survey was administered using the 24-h dietary recall method, and intakes of nutrients and food groups were analyzed. Body composition was evaluated using dual-energy x-ray absorptiometry (DEXA). Body composition abnormalities include low bone mass (T-score<-1.0), low muscle mass (weight-adjusted appendicular skeletal muscle mass below the mean reference value of healthy young adults), and obesity (waist circumference ≥85 cm). The associations between nutrient intake and fruit groups and the number of abnormalities in body composition were tested by logistic regression analysis.

RESULTS

The intakes of vitamin C and potassium per 1000 kcal of total energy intake were significantly lower in women with a larger number of abnormalities in body composition (p = 0.0155 and p = 0.0037, respectively). After controlling for covariates, women with a high intake of fruit (≥257.4 g/d) had a significantly reduced likelihood of multiple abnormalities in body composition compared with women with no fruit intake (p for trend: p < 0.01 for those with one, two, or three abnormalities).

CONCLUSIONS

Intake of fruits rich in vitamin C and potassium may help to decrease OSO-related risks in middle-aged postmenopausal women.
