Neighborhood Matters, Block by Block

Feb. 24, 2016

The Flint water crisis is a stark and grim reminder of the connections among housing, neighborhoods, and health. But neighborhoods influence health and well-being in more subtle ways that do not often make the national news. Living amidst poverty and violence can affect individuals and their life-course in ways that are hard to measure, yet important to discern.

Researchers interviewed patients who were recruited to participate in the care management program but had dropped out or never participated despite recruitment efforts. The most commonly cited barriers to participation were a lack of perceived need and a sense of distrust toward the program and its staff. These findings could help care management...

In Pediatrics, Christina Roberto and colleagues examine how health warning labels on sugar-sweetened beverages may influence parents and which types of labels are most impactful. In this study, parents participated in an online survey that randomly assigned them to one of 6 different beverage labels. Parents were then asked to choose a beverage for their child in a vending machine, rate perceptions of different beverages, and indicate interest in receiving beverage coupons. Significantly fewer parents chose sugary beverages for their child when presented with a warning label,...

In The Diabetes Educator, Monica Ferguson and colleagues, including Judith Long, Dylan Small, Henry Glick and Marilyn Schapira, investigate whether low health literacy is associated with inaccurate perceptions of diabetes control. The researchers conducted a cross-sectional analysis on adults with type 2 diabetes whose A1C levels are poorly controlled (>8% A1C). Perceived control and factors associated with outcomes, including health literacy, were assessed during an in-person interview. The researchers find that in the population of patients with poorly controlled diabetes, a...

Employers Take Note: Premium-Based Incentives For Weight Loss Don't Work

Jan. 5, 2016

A new study casts doubt on the effectiveness of reducing health insurance premiums as a way to encourage employees to lose weight. LDI Senior Fellow Mitesh Patel and his team, in a randomized controlled trial, test the effectiveness of a $550 incentive in promoting weight loss in obese employees. They found no difference in weight loss over the course of one year between the control group and three different kinds of incentive programs.

This provision, rolled out between September 2010 and January 2011, applies to all private insurance plans and exempts ‘grandfathered plans’. In this study, LDI Senior Fellow Shivan Mehta and colleagues investigated whether this ACA provision has its intended effect on colonoscopy and mammography rates.
