Background: Osteoarthritis is common in the aging dog and is associated with chronic pain and impaired mobility. The main objective of this study was to determine whether low‐level laser therapy (LLLT) would increase physical activity in dogs with osteoarthritis. Methods: Twenty‐three dogs with osteoarthritis were instrumented with an accelerometer 48 h before the first LLLT session (baseline), to record daily activity. Each dog underwent six consecutive weekly laser treatments. The scores of the Canine Brief Pain Inventory and the Liverpool Osteoarthritis in Dogs' were recorded for clinical purposes, as a tool to titrate the analgesic therapy of each individual dog, before LLLT (as baseline) and then weekly for 6 weeks. Results: The number of daily activities increased during week 2 (161,674; SD, 103,666) and remained higher than baseline (93,481; SD, 107,878) until week 6 (179,309; SD, 126,044; p < 0.001). Daily step count increased from week 1 (4472; SD, 3427) compared to baseline (1109; SD, 1061) and remained higher than the baseline until the end of week 6 (8416; SD, 3166; p < 0.001). Average energy expenditure during the study period was 179 [range, 2–536] kcal/day; there were no statistically significant differences in this variable between weeks of treatment. Systemic analgesics therapy was decreased in 50% of the dogs during the study period. Conclusions: Laser therapy may advance the management of osteoarthritis by increasing the level of activity of dogs, therefore improving their quality of life. [ABSTRACT FROM AUTHOR]

Summary: Street connectivity, as a neighbourhood built environmental factor, may affect individual physical activity (PA) and subsequently weight status. However, these associations remain inconclusive. This study aimed to systematically review the association between street connectivity and childhood obesity. A literature search was conducted in the Cochrane Library, PubMed, and Web of Science for articles published before January 1, 2019. All original studies that investigated the association between street connectivity and weight‐related behaviours or outcomes among children and adolescents were included. Forty‐seven articles were identified, including eight longitudinal and 41 cross‐sectional studies conducted in eight countries. The sample size ranged from 88 to 46 813. Street intersection density (SID), measured by Geographic Information Systems in 36 studies and reported in 13 studies, was the main indicator used to represent street connectivity. Forty‐four studies examined the association between SID and weight‐related behaviours, including overall PA (n = 15), moderate‐to‐vigorous PA (n = 13), active transport (n = 12), dog walking (n = 1), walking (n = 1), sedentary behaviours (n = 2), and TV viewing (n = 1). Fifteen studies focused on the association between SID and weight‐related outcomes. Overall, evidence from this systematic review and meta‐analyses suggested a positive association between street connectivity and PA. However, it was difficult to draw a conclusion on the association between street connectivity and BMI. More longitudinal evidence is needed to confirm the causal association between street connectivity and weight status. [ABSTRACT FROM AUTHOR]

Background: Dog ownership has been associated with higher rates of physical activity (PA) in several populations but no study to date has focused on cancer survivors. The purpose of this study was to examine the associations between dog ownership and PA among cancer survivors and to examine correlates of dog ownership.Methods: A stratified random sample of 2062 breast cancer survivors, prostate cancer survivors, and colorectal cancer survivors was mailed a questionnaire assessing PA, social cognitive, dog ownership, demographic, and medical variables.Results: Overall, 25% of the sample was dog owners (DOs). There were no significant differences in moderate, vigorous, or total PA minutes between DOs and non-dog owners. There was a significant difference in light PA minutes in favor of DOs (153 vs 112 minutes; 95% CI = 4 to 77; P = .030), however, this was largely restricted to breast cancer survivors (143 vs 79 minutes; 95% CI = 25 to 102; P = .001) who also reported fewer vigorous PA minutes (18 vs 39 minutes; 95% CI = -42 to -1; P = .042). Survivors were more likely to be DOs if they had breast cancer (P = .054), a higher income (P = .021), radiation therapy (P = .029), chemotherapy (P = .010), were younger (P < .001), employed (P < .001), and a current smoker (P = .015). Few social cognitive variables were associated with DO.Conclusions: Dog ownership among cancer survivors was not associated with moderate-to-vigorous PA but was associated with light PA. Further research is necessary to determine if promoting dog ownership and dog walking among cancer survivors may increase PA and possibly improve health outcomes. [ABSTRACT FROM AUTHOR]

OBJECTIVES: To examine dog walking among dog owners and the relationship between walking behavior of dog owners and non-dog owners and maintained gait speed over 3 years. DESIGN: Cross-sectional and longitudinal analyses of a prospective cohort study. SETTING: Memphis, Tennessee, and Pittsburgh, Pennsylvania. PARTICIPANTS: Two thousand five hundred thirty-three community-dwelling adults aged 71 to 82 at 36 months of the Health, Aging and Body Composition Study. MEASUREMENTS: Dog ownership, reported walking behavior, change in walking behavior, and usual and rapid gait speed over 3 years. RESULTS: Of 394 dog owners, only 36% walked their dogs at least three times per week. Cross-sectionally, dog walkers were more likely to achieve 150 minutes of walking per week and had faster usual and rapid walking speeds (1.20 vs 1.14 m/s and 1.62 vs 1.52 m/s, respectively; P<.01 for both) than non-dog owners who did not walk at least three times per week and similar speeds as non-dog owners who walked at least 150 minutes per week ( P>.50). Three years later, subjects who had been dog walkers at baseline were approximately twice as likely as any other group to achieve recommended walking levels, independent of covariates. Dog walkers experienced similar declines in usual and rapid walking speed as non-dog owners who walked at least three times per week but maintained their initial mobility advantage. CONCLUSION: Although dog ownership appears to facilitate walking behavior, only a minority of older dog owners walk their dogs. The mobility advantage of dog ownership was seen only in dog walkers and was similar to that associated with any walking. Given suboptimal walking activity in older adults, examining the degree to which dog ownership promotes walking activity in persons who do little walking on their own appears worth pursuing.
