Correlation analysis of the bone mass and nutritional status of 30-49-year-old female teachers in Guangzhou / 中国组织工程研究

ABSTRACT

BACKGROUND: Female teachers aged 30-49 years old are the backbone of the school teaching and management. However, the occupation stress, family burden and other factors may lead to their physiological and psychological disorders. Moreover, the age of 30-49 years is an important period that the female indicators begin to decrease, so their nutritional status, blood pressure and bone status should be paid more attention. OBJECTIVE: To evaluate the bone mass and nutritional status of female teachers aged 30-49 years old in Guangzhou, thus providing scientific advice for exercise plan. METHODS: Totally 226 healthy female teachers aged 30-49 years old were selected, and their body shape indexes, blood pressure and bone density were tested to analyze the correlation of age, height, body mass, body mass index, waist-hip ratio, blood pressure and bone density. RESULTS AND CONCLUSION: In 30-49-year old female teachers, the malnutrition rate decreased with aging, while the prevalence of overweight and obesity significantly increased with aging (P < 0.01). Correlation analysis showed that the blood pressure was positively correlated with age, height, body mass, body mass index, waist-hip ratio and body fat percentage (P < 0.01), but the bone density was little affected by all above indexes (P > 0.05). Beside, the prevalence of osteoporosis in the 30-34 years old group was significantly higher than that in the other groups (P < 0.01). These results indicate that female teachers aged 30-49 years in Guangzhou exhibit a reduction in the malnutrition rate but an increase in the risk of obesity and prevalence of hypertension with aging. However, age at onset of osteoporosis tends to be younger in patients.
