Assessing impacts of redeveloping public housing communities on obesity in low-income minority residents: Rationale, study design, and baseline data from the Watts Neighborhood Health Study.

Introduction: Obesogenic built- and social-environments in low-income and minority communities are often blamed for the higher rates of obesity in this population, but existing evidence is based largely on observational studies. This study leverages a natural experiment created by the redevelopment of a public housing community to examine the impact of major improvements to the housing, built, and social environments on obesity among residents.

Methods/design: The study design is a natural experiment where residents from the redeveloped community (treatment group) will be compared to those from a similar community (control group) in terms of their pre/post changes in primary outcomes using annual longitudinal data on a cohort of residents.

Cognitive Impairment and Social Security's Representative Payee Program.

Social Security's Representative Payee Program faces a difficult balance with respect to dementia: Many people living with dementia can conduct their finances without a payee if they have help from informal caregivers, but those without help are at risk. To date, it has been unclear what share of retirees with dementia use a payee, what share has help potentially available from another source, and what share has no observed means of assistance. This study finds that while fewer than 10% of retirees with dementia use a payee, only about 8% have no observed means of help.
