Effect of insulating existing houses on health inequality: cluster randomised study in the community
TLDR
Insulating existing houses led to a significantly warmer, drier indoor environment and resulted in improved self rated health, self reported wheezing, days off school and work, and visits to general practitioners as well as a trend for fewer hospital admissions for respiratory conditions.
Effects of price discounts and tailored nutrition education on supermarket purchases: a randomized controlled trial.
TLDR
Neither price discounts nor tailored nutrition education had a significant effect on nutrients purchased, but the significant and sustained effect of discounts on food purchases suggests that pricing strategies hold promise as a means to improve population diets.
Inequalities in non-communicable diseases and effective responses
Unemployment and suicide. Evidence for a causal association?
TLDR
Being unemployed was associated with a twofold to threefold increased relative risk of death by suicide, compared with being employed, and about half of this association might be attributable to confounding by mental illness.
Foods and Dietary Patterns That Are Healthy, Low-Cost, and Environmentally Sustainable: A Case Study of Optimization Modeling for New Zealand
TLDR
These results could help guide central and local government decisions around which foods to focus policies on, which is which foods are most suitable for: food taxes (additions and exemptions); healthy food vouchers and subsidies; and for increased use by public institutions involved in food preparation.
Probabilistic record linkage and a method to calculate the positive predictive value.
TLDR
A 'duplicate method' to calculate the PPV of record linkage when each record can only be involved in one match is described, which is ideal for linkage projects using anonymous data.
Food Pricing Strategies, Population Diets, and Non-Communicable Disease: A Systematic Review of Simulation Studies
A systematic review of simulation studies conducted by Helen Eyles and colleagues examines the association between food pricing strategies and food consumption and health and disease outcomes.
The contextual effects of neighbourhood access to supermarkets and convenience stores on individual fruit and vegetable consumption
TLDR
Little evidence that poor locational access to food retail provision is associated with lower fruit and vegetable consumption is found before rejecting the commonsense notion that neighbourhood access to fruit and vegetables affects personal consumption.
