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.

Bacterocera zonata is a very serious pest of fruit crops especially mangoes over the globe. The present study was conducted to observe oviposition deterrence in B. zonata under lab conditions. Mangoes (Desi, Chaunsa and Anwar Ratool) were treated with ant cues and entomopathogenic Beauveria bassiana. Oviposition deterrence was recorded when nonspecific and variety specific (Chaunsa, Anwar Ratol) mangoes were treated with ant cues and B. bassiana at different intervals (exposure to 4 days). It showed that the mean number of oviposition punctures tend to increase with time. Minimum fruits puncture was found at day 1 in B. bassiana treated mangoes, while at 4th day, maximum number of punctures were observed in untreated mangoes. B. bassiana treated mangoes showed minimum number of punctures than ant cues and untreated mangoes were observed with highest number of punctures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
