The purpose of this prospective cohort study was to determine whether the maximal width of the base of support (BSW) measure is able to predict the risk of multiple falls in community-dwelling women. Thirty-eight community-dwelling women (mean age of 72 ± 8 years old) participated. Falls were prospectively recorded during the following year. Overall, 29 falls were recorded; six (16%) women were multiple fallers and 32 (84%) were nonfallers. There was a significant difference in the BSW between the fallers and nonfallers (F[1, 37] = 5.134 [p = .030]). A logistic regression analysis indicated a significant contribution of the BSW test to the model (odds ratio = 0.637; 95% CI [0.407, 0.993]; p = .046 per 1 cm).The cut-off score was determined to be 27.8 cm (67% sensitivity and 84% specifcity). These results indicate that women with a smaller BSW at baseline had a significantly higher risk of sustaining a fall.

To evaluate the longitudinal association between physical activity behavior at 11 years of age and the incidence of mental health problems from 11 to 15 years of age.
Individuals born in the city of Pelotas, Brazil, in 1993 have been followed up since birth. At 11 and 15 years of age, mental health was assessed using the Strengths and Difficulties Questionnaire (SDQ). At 11 years of age, physical activity was assessed through a validated questionnaire. The continuous SDQ score at 15 years was used as the outcome variable. The main exposure was physical activity behavior at 11 years of age divided into 3 categories (0, 1−299, >300 min/wk).
The incidence of mental health problems from 11 to 15 years was 13.6% (95% CI, 12.4−14.9). At 11 years, 35.2% of the adolescents achieved 300 min/wk of physical activity. In the unadjusted analysis, physical activity was inversely related to mental health problems (P = .04). After adjustment for confounders, the association was no longer significant in the whole sample but was still significant among boys.
Physical activity appears to be inversely related to mental health problems in adolescence, but the magnitude of the association is weak to moderate.

To explore cross-sectional and longitudinal associations between self-reported and accelerometry-based physical activity (PA) and blood pressure (BP) between 11 and 14 years of age.
Prospective birth cohort study in Pelotas, Brazil. Participants were 427 cohort members who were followed up with at 11, 12, and 14 years of age, and had questionnaire data on PA and BP at 11 and 14 years, as well as accelerometry and questionnaire data on PA at 12 years. Outcome measures were continuous systolic and diastolic BP at 14 years, and change in BP from 11 to 14 years.
PA was unrelated to systolic BP in any analyses. PA measured by accelerometry at 12 years, but not questionnaire-derived PA, was inversely associated with diastolic BP at 14 years of age in fully adjusted models. Those who exceeded the 300-minutes PA threshold at all 3 visits had a 2.6 mmHg lower mean increase in DBP from 11 to 14 years compared with those classified below the threshold in all visits.
Accelerometry-based PA was longitudinally inversely associated with diastolic BP. This finding was not evident when analyzing self-reported PA at a given age, suggesting a possible underestimation of the association when using subjective data.

Participants who completed a 3-month prescribed individualized exercise program in groups were followed-up prospectively. The aims were to describe the characteristics of the participants, their health-related quality of life (HRQoL) and physical fitness at baseline, at completion and at 12-month follow-up, and to identify predictors of HRQoL and physical fitness at completion and at 12-month follow-up.
A 1-group follow-up design was used. Data were collected from records of 163 attendees at a municipality-sponsored health center in Norway. HRQoL was measured by self-report using the COOP/WONCA questionnaire. Physical fitness was estimated from the results of a 2-km walk test.
Of the 163 participants referred to the clinic, 130 (79.8%) were women and 33 were (20.2%) men. Participants who completed were older than those who dropped out. The participants showed clinical improvement in physical fitness and all health-related quality life domains (d > 0.53) at the completion of the program and in physical functioning, mental health, performance of daily activities, overall health, and perceived improved health after 12 months (d > 0.36).
Participation in group-based prescribed exercise program for 3 months may improve physical fitness and HRQoL significantly in short and long terms.

Osteoporosis is a systemic disease characterized by the increase of bone fragility and fracture risk. Postmenopausal female osteoporotic patients were randomized into three groups: balance and coordination, strengthening, and aerobic exercise. The exercise programs were performed for 12 weeks, 1 hr each day for 3 days of the week. Patients were followed-up for 12 weeks after the initial intervention. After the exercise program, patients continued their daily life activities and were called back to the clinic for additional testing after 12 weeks. Static and dynamic balance measurements and pain and life quality assessments were performed at enrollment, and at the 12th and 24th weeks. Significant improvements in both the Timed Up and Go test and Berg Balance Scale values at the 12th week were only observed in the balance-coordination group. There were statistically significant improvements in night and daytime pain visual analog scale scores at the 12th and 24th weeks in the strengthening exercise group. No patient experienced falling during the 24th week follow-up. The strengthening exercises were observed to be more effective in pain reduction, and balance and coordination exercises were found to be more effective in improvement of static and dynamic balance.
