Physical Activity Increases Bone Size in Prepubertal Boys and Bone Mass in Prepubertal Girls: A Combined Cross-Sectional and 3-Year Longitudinal Study

Background:This longitudinal study aimed to examine if a Movability Index (MI), based on objectively measured built environment characteristics, was a determinant for objectively measured physical activity (PA) among young adults.Methods:Data collected from 177 persons participating in the Danish part of the European Youth Hearth Study (EYHS) was used to examine the effect of the built environment on PA. A MI was developed using objectively measured built environment characteristics, and included residential density, recreational facilities, daily destinations and street connectivity.Results:Results showed a positive cross-sectional association between MI and PA. PA decreased from baseline to follow-up. MI increased, primarily due to participants relocating to larger cities. An increase in MI from baseline to follow-up was associated with a reduced decrease in PA for females.Conclusions:Our findings suggest that the built environment is a determinant for PA, especially for females. The found gender differences might suggest the need to develop gender specific environmental indices in future studies. The validity of the measures can be further improved by creating domain specific PA measures as well as domain specific environmental indices and this can potentially reveal more specific built environment determinants for PA.

Abstract Background To evaluate the association of physical activity (PA) intensity with cognitive performance at baseline and during follow-up. Methods A total of 4039 participants aged 45 years or above from the China Health and Retirement Longitudinal Study were enrolled in visit 1 (2011–2012) and followed for cognitive function in visit 2 (2013–2014), visit 3 (2015–2016), and visit 4 (2017–2018). We analyzed the association of PA intensity with global cognition, episodic memory, and mental intactness at baseline using adjusted regression methods and evaluated the long-term effect of PA intensity using multiple measures of cognition scores by mixed effect model. Results In cross-sectional analysis, mild and moderate PA, rather than vigorous PA, was associated with better cognitive performance. The results remained consistent in multiple sensitivity analyses. During the follow-up, participant with mild PA had a 0.56 (95% CI 0.12–0.99) higher global cognition, 0.23 (95% CI 0.01–0.46) higher episodic memory, and 0.33 (95% CI 0.01–0.64) higher mental intactness, while those with moderate PA had a 0.74 (95% CI 0.32–1.17) higher global score, 0.32 (95% CI 0.09–0.54) higher episodic memory, and 0.43 (95% CI 0.12–0.74) higher mental intactness, compared with individuals without PA. Vigorous PA was not beneficial to the long-term cognitive performance. Conclusions Our study indicates that mild and moderate PA could improve cognitive performance, rather than the vigorous activity. The targeted intensity of PA might be more effective to achieve the greatest cognition improvement considering age and depressive status.

Sectional Analysis

BackgroundPhysical inactivity has been linked to headache disorders, but data regarding the current recommended leisure-time (LTPA) and commuting physical activity (CPA) levels is unknown.ObjectiveTo test the associations between headache disorders (definite and probable migraine tension type headache-TTH) and physical inactivity in these domains (LTPA and CPA) in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil).MethodsIn a cross-sectional analysis, logistic regression models computed the odds ratio (OR) for the relationship between headache disorders and physical activity (LTPA and CPA) in the following levels: “active” (Reference), “insuciently active”, and “inactive”. The full models were controlled for the effects of sociodemographic data, cardiovascular risk profile, and use of headache medication (migraine prophylaxis)ResultsOf 15,0105 participants, 14,847 (45.6 % of men and 54.4 % women) responded the baseline interviews regarding physical activity levels and headache disorders. Overall, most significant physical inactivity was observed in LTPA domain for definite migraine [OR: 1.32 (1.10-1.57)] and probable migraine [OR: 1.33 (1.17-1.50)]. Similar findings were replicated by sex. Physical inactivity (LTPA) was positively associated with definite migraine in women [OR: 1.29 (1.04-1.59)], probable migraine in both men [OR: 1.40 (1.15-1.69)] and women [OR: 1.29 (1.04-1.59)]. Physical inactivity in CPA domain was associated to increased OR for probable TTH in men [OR: 1.33 (1.01-1.75)], while CPA was inversely associated to definite migraine [OR: 0.79 (0.64-0.98)] and probable migraine [OR: 0.80 (0.67-0.96)] in women. Considering all headaches, unmet vigorous physical activity levels were associated to increased OR for definite migraine [OR: 1.36 (1.13-1.65)] and probable migraine [OR: 1.37 (1.20-1.57)]. Finally, we found higher odds for daily headaches among LTPA-inactive [OR: 1.73 (1.20-2.49)] and CPA-insufficiently active [ OR: 1.36 (1.04-1.79)] participants.ConclusionPhysical inactivity is associated with headache disorders in the ELSA-Brasil study, with distinct associations regarding headache subtype, sex, physical activity domain and intensity, and headache frequency.

Abstract: Osteoporosis is three times more likely to happen to menopause patients with low physical activity because it causes the bone mass to decrease. Standard examination for osteoporosis is a bone mass examination or also known as BMD (Bone Mass Densitometry). This research aims to identify the correlation between physical activity and bone strength in menopause patients. This is an observational analytical research which used cross-sectional design. The sample consists of 74 patients from Kemenpora National Hospital in 2017. The data were analyzed by using Chi-square test. The result shows that 37% of low physical activity patients have normal bone strength, 63% of which have osteopenia and 20% of the patients have osteoporosis. Meanwhile, 52% of medium physical activity patients have normal bone strength, 19% of the patients have osteopenia, and 33% of the patients have osteoporosis. 16% of patients with high physical activity have normal bone strength, 18% of the patients have osteopenia, and 47% of the patients have osteoporosis. This research proves that there is a correlation between physical activity and bone strength in menopause patients (p = 0,004). Keywords: Physical Activity, Bone Mass Densitometry, Menopausal Women
