Brief Summary

The 1.2 million households living in public housing are disproportionately affected by obesity, where prevalence is estimated at 50%. An ecologic framework hypothesizes that this disparity is related, in part, to social and environmental factors within these neighborhoods that influence residents' lifestyles. Social networks and the built environment may work together to promote or inhibit lifestyle behaviors; however, combined social network-built environment interventions have not previously targeted changes in diet. Investigators hypothesize that an intervention that combines a social network approach with strategies that address public housing residents' challenges related to the built environment will improve dietary habits. The investigators' overall aim is to develop a combined social network-built environment intervention to reduce intake of beverages high in added sugars and to pilot test the intervention among residents of public housing developments in Baltimore, MD. The investigators' aim for this work is: 1) To develop a combined social network-built environment intervention to reduce intake of beverages high in added sugars and to pilot test the intervention among residents of public housing developments in Baltimore, MD. Investigators hypothesize that a social network intervention will be feasible and acceptable in promoting healthy lifestyle change, and that this intervention will alter lifestyle behaviors among public housing residents.

Outcome Measures

Primary Outcomes (4)

• Number of Sessions Attended

  Number of sessions attended calculated from attendance sign-in sheets. This is used for the assessment of program feasibility.

  3 months

• Participant Satisfaction as Assessed by 4-point Likert Scale

  Survey question assesses participant satisfaction with the intervention using a 4-point Likert scale (1 = Very satisfied; 2= Somewhat satisfied; 3 = Somewhat dissatisfied; 4 = Very dissatisfied). This is used for the assessment of program acceptability.

  6 months

• Participant's Likelihood to Recommend Program Assessed by 4-point Likert Scale

  Survey question assesses willingness to recommend that a friend participate using a 4-point Likert scale (1 = Very likely; 2= Somewhat likely; 3 = Somewhat unlikely; 4 = Very unlikely). This is used to assess the program acceptability.

  6 months

• Added Sugar Intake (Teaspoons/Day) Among Total Sample at Follow up

  Participants answered questions from the National Health Interview Survey (NHIS) 5-factor dietary screener, and relevant elements as recommended by NHIS were combined to estimate the daily added sugar intake (i.e.,soda, sugar-sweetened beverages, sweets and doughnuts). At 6 months, this measure ranged (min-max) from 9.1 to 56.0 teaspoons/day in this sample. The American Heart Association recommends that all adults limit their added sugar intake to no more than 9 teaspoons per day.

  6 months

Secondary Outcomes (3)

• Added Sugar Intake (Teaspoons/Day) Among Alters ("Sidekicks") at Follow up

  6 months

• Added Sugar Intake (Teaspoons/Day) Among Egos ("Peer Educators") at Follow up

  6 months

• Median Weight at Follow up

  6 months

Study Arms (1)

Social network intervention

EXPERIMENTAL

Individuals will be recruited and trained to be "Peer Educators" who will participate in group sessions and then communicate this information with members of participant's social network ("Sidekick") and work to make changes to reduce intake of sugar-sweetened beverages. Peer Educators will participate in 6 core group sessions over a 6-week period as well as 3 additional booster sessions over the subsequent 3 months after completing the core curriculum. All sessions will be delivered by a facilitator and assistant facilitator using a guide.

Behavioral: Social network intervention

Interventions

Social network intervention BEHAVIORAL

The intervention combined a social network approach with strategies that address public housing residents' challenges related to the built environment to improve dietary habits. Given the frequent intake of sugar-sweetened beverages (SSB) in this population, the intervention focused on reducing added sugar intake through the reduced consumption of SSB.
