PowerUp for Health: A Diabetes Prevention Program for Men

During year one, the multi-disciplinary research team will work closely with the expert and
community Advisory Panel and consultants to adapt the standard NDPP curriculum in order to
promote increased engagement of men. "Engagement" is defined in this proposal to include
recruitment, group participation and retention in the 16-week program. This modified NDPP♂
(i.e., for men) renamed by the advisory panel as "Power Up for Health," will have only
NDPP-trained male coaches and male participants, with adaptations to dietary and physical
activity messaging and a new behavioral "toolbox" approach developed for men.

By month 10 of year one, investigators will begin implementation of the 16-week pilot studies
of the NDPP♂ at 6 NYC Parks and Recreation Department (REC) sites in disadvantaged
communities in three of the NYC boroughs currently offering the standard NDPP programming.
Investigators will utilize an iterative and adaptive process during the pilot phase to modify
recruitment and retention strategies, as well as the NDPP curriculum and activities. The
exploratory aim, as feasible, is to then compare the adapted NDPP♂ pilot data to the standard
NDPP mixed-gender groups' available data on recruitment, participation, weight loss, and
retention of men from similar NYC neighborhoods. The goal will be pilot study data from 15-20
male participants at each REC pilot site—a recruitment goal of 120 male participants. Working
in collaboration with the investigators' consultants and Advisory Panel of community leaders
and academic experts in men's health promotion, as well as study partners at the NYC
Department of Parks and Recreation, investigators will conduct focused outreach to the target
populations.

The Specific Aims for the Pilot Study are:

Aim 1. to collaborate with the expert and community Advisory Panel to complete the adaptation
of the NDPP curriculum and the recruitment and retention activities to better engage men with
prediabetes from disadvantaged communities of NYC;

Aim 2. to assess preliminary indicators of effectiveness of the NDPP♂ with respect to
reductions in body weight; Hypothesis 1: Men engaged in the NDPP♂ will have reductions in
body weight at 16 weeks at least equivalent to the NDPP goal of 5-7% of their baseline body
weight.

Aim 3. to examine and describe from pilot data the extent to which recruitment, intervention
and retention strategies, tailored for men with prediabetes are associated with improved
engagement of the target population; Exploratory Hypothesis 3.1: Recruitment of men to NDPP♂
will occur more rapidly and with less intensive strategies than recruitment of men to the
standard NDPP in comparable communities.

Exploratory Hypothesis 3.2: Men enrolled in the NDPP♂ will be more engaged in program
activities and self-report greater improvements in healthy eating and physical activity
compared with men in the standard NDPP.

Exploratory Hypothesis 3.3: Men enrolled in the NDPP♂ will have retention rates that are at
least equivalent to men in the standard NDPP.

All comparison data analyses are exploratory and as data are available.

Aim 4. to examine preliminary data to identify demographic, psychosocial, neighborhood, and
REC site characteristics associated with differential recruitment, retention and intervention
effects in the NDPP♂.
