Associations of changes in physical activity and diet with incident obesity and changes in adiposity: Longitudinal findings from the UK Biobank.
We examined the association of changes in physical activity and diet with obesity development and changes in body fat percentage, body mass index, and waist circumference. 31,344 adults without obesity at baseline (age = 56.0 ± 7.5 years; female = 49.1%) from the UK Biobank were included. Physical activity was categorised based on public health guidelines as: inactive; insufficient; and sufficient. Diet category was assigned based on an established composited score that included consumption of fruits, vegetables, fish, red meat (unprocessed), and processed meat. ⋯ In those who decreased physical activity obesity was attenuated when combined with diet improvement. Improvements in physical activity or diet mutually attenuated the deleterious associations of the other behaviour's deterioration. In most analyses, increases in physical activity conferred consistent positive associations against the development of obesity, across dietary change groups.

ReviewA systematic review of recurrent firearm injury rates in the United States.
To conduct a systematic review of methodologies, data sources, and best practices for identifying, calculating, and reporting recurrent firearm injury rates in the United States. ⋯ Variability in both the data sources and methods used to evaluate and report recurrent firearm injury limits individual study generalizability of individual and societal factors that influence recurrent firearm injury. Our systematic review highlights the need for development, dissemination, and implementation of standard practices for calculating and reporting recurrent firearm injury.

Meta AnalysisEconomic burden of low cardiorespiratory fitness in Canada.
The objective of this study was to estimate health care and health-related productivity costs associated with low cardiorespiratory fitness (CRF) in Canadian adults. We also estimated costs that would be avoided by a 10 percentage point prevalence reduction in low CRF. A prevalence-based approach was used to estimate the economic costs associated with low CRF. ⋯ An absolute 10% reduction in the prevalence of low CRF (from 45.5% to 35.5%) would save an estimated CAD$644 million per year in costs. In conclusion, low CRF is an important contributor to the economic burden of illness in Canada. Evidence-based and cost-effective strategies that aim to increase CRF at the population level may help alleviate health care costs and improve health.

Associations between precarious employment and smoking and regular exercise: Results from a Korean longitudinal panel study from 2005 to 2020.
We examined whether precarious employment (PE) is related to cigarette smoking and physical inactivity and whether a longer duration of PE intensifies the detrimental impact. Using Korean longitudinal panel data, 89,289 observations of 15,712 employees were analyzed. Mixed models were applied to estimate the odds ratio (OR) and 95% confidence intervals (CIs). ⋯ Over 6 years of PE was associated with the highest risk of smoking initiation (2.02 [1.28-3.19]) and the lowest likelihood of exercise initiation (0.42 [0.32-0.55]) in men. However, a longer duration of PE was not associated with a change in health behaviors in women. Our findings highlight that PE have a detrimental impact on health behaviors.

Maternal lifestyle and nutrient intakes during pregnancy and exclusive breastfeeding in relation to risk factors for breast cancer: The Japan Environment and Children's Study.
Breastfeeding has many benefits for infant growth and maternal health, such as reducing breast cancer risk. However, data on maternal factors influencing breastfeeding are insufficient. To clarify the associations between maternal lifestyle and diet during pregnancy and exclusive breastfeeding (EBF), we conducted a prospective study of pregnant women within the framework of the Japan Environment and Children's Study (a nationwide birth cohort study). ⋯ Dietary fiber intake was also associated with the continuation of EBF (p trend = 0.048). These findings indicate that maternal lifestyles during pregnancy affect lactation performance. Lifestyle adjustments during pregnancy may have favorable effects on maternal and children's health through successful breastfeeding.
