Hand grip strength and maximum peak expiratory flow: determinants of bone mineral density of adolescent students

We thought that grip strength in patients with IDDM would be associated with hand BMD of patients and we thought that patients with IDDM have lower hand BMD than normal subjects.Therefore in this study, the evaluation of the relationship between hand grip strength and hand bone mineral density in healthy children and in children with insulin dependent diabetes mellitus was studied. The hand grip strength, hand and axial bone mineral density of patients were also compared to age-matched healthy controls. We studied 31 consecutive outpatients with insulin dependent diabetes mellitus defined in accordance to the World Health Organization criteria, who attended to the diabetic outpatient clinic. Thirty two healthy children were included as control group. There were no differences in the age, body mass index, bone age, serum Ca and P levels between the diabetic patients and the controls (p > 0.05). There were no significant differences between the groups in hand grip strength, total hand and axial bone mineral density (p > 0.05). There were significant correlations between hand grip strength and hand bone mineral density r = 0.824, p = 0.000), axial bone mineral density (r = 0.714, p = 0.000), bone age (r = 0.830, p = 0.000) and duration of insulin dependent diabetes mellitus in the diabetic group (r = 0.463, p = 0.009). When linear multiple regression analysis was performed hand grip strength and bone age were independent predictors of hand BMD (p < 0.05). We found that hand grip strength significantly correlated with the hand and axial bone mineral density in patients with insulin dependent diabetes mellitus. We suggest that strengthening exercises should be encouraged to increase bone mineral density in these patients.

Menopausal Women

Introduction. The onset of the menopause entails numerous changes, both physical and mental, in the functioning of the bodies of women. Moreover, the early menopause increases the risk of occurrence of many civilization-related diseases. Major factors contributing to health deficits include lowered bone mineral density and sarcopenia, which can result in serious functional limitations and the acceleration of ageing processes in the body. The aim of this study was to determine how the menopause onset age is linked with bone mineral density and the strength of selected muscles of the limbs and the trunk. Material and Methods. 756 women aged 50-80 years were subjected to tests. The subjects were divided into three groups: (I) from 50 to 59 years, (II) from 60 to 69 years, and (III) from 70 to 79 years. Each of the women specified the age when her final menstrual period occurred. On this basis, groups of women with (1) the early menopause—before the 50th year of life—and (2) with the late menopause—after the 50th year of life—were distinguished. Bone mineral density (BMD), dominant hand grip strength, knee extensor and flexor strength, and functional upper and lower body muscle strength were determined in each of the women. Results. The test results indicate differences in levels of muscle strength and BMD between the 50-year-old early- and late-menopausal women. The late-menopausal women score better motor ability test results and higher BMD values. The differences decrease in the groups of 60-year-old women, whereas the 70-year-old early- and late-menopausal women score similar results. Conclusions. A higher percentage of women with a lowered bone mass and a lower strength level was found in the group of early-menopausal subjects. The rate of decline in hand grip strength, the functional efficiency of the upper and lower limbs, and BMD is faster in the late-menopausal women, whereby the two groups of 70-year-old women score similar test results.

Expiratory Flow

The manifestation of muscle dysfunction associated with diabetes is commonly observed in skeletal muscles. The negative effect of hyperglycemia on muscle function is systemic and it may extend to abdominal muscles. Hence, the purpose of this study was to determine whether hand grip strength (HGS), an indicator of peripheral muscle strength, correlates with peak expiratory flow (PEF), which reflects the strength of abdominal muscles, among middle-aged and older Chinese individuals with diabetes. After controlling for all variables except for physical activity, 10 L/min increase in PEF was associated with 0.2 kg increase in HGS (β = .02, p < .0001). In the model additionally controlling for physical activity, the effect size of PEF on HGS did not change (β = .02, p < .0001). Our results suggest that among individuals with diabetes, PEF is positively related to HGS. The relationship may suggest a decline in PEF and a weakness of abdominal muscles.

Abstract Objective: To explore the association of handgrip strength and peak expiratory flow rate with site-specific bone mineral density T scores, and to study the correlation of body mass index and physical activity with the three parameters. Methods: The cross-sectional study was conducted in November 2018 at the Combined Military Hospital, Lahore Medical College and Institute of Dentistry, Lahore, Pakistan, and comprised healthy young adults. Data was collected using the international physical activity questionnaire. The subjects were grouped into low, moderate and high categories. Handgrip strength, peak expiratory flow rate, bone mineral density T scores and body mass index were measured for each subject. Data was analysed using SPSS 24. Results: Of the 102 subjects, 52(50.9%) were males and 50(49%) were females. There was a significant difference between the median values for all parameters of males and females (p<0.05). Bone mineral density and physical activity were moderately associated with handgrip strength and peak expiratory flow rate (p<0.05). Body mass index showed a moderate association with bone mineral density (p<0.05). Conclusion: Healthy young adults with better respiratory function and handgrip strength were found to have higher values of site-specific calcaneal bone mineral density. Subjects with higher reported levels of physical activity and a higher body mass index within a healthy range presented with improved values of bone mineral density, handgrip strength and peak expiratory flow rate. Key Words: Bone mineral density, Handgrip strength, Peak expiratory flow rate, Body mass index, Physical activity. Continuous...
