Much has been learned about the efficacy and effectiveness of comprehensive healthy lifestyle
interventions to reduce obesity. Few studies have been translated into rural settings or
among Latinos. Y Living is an evidence-based family-focused intervention (FI) designed for
urban Latino families. The FI is a 12-week behavioral modification program grounded in social
cognitive theory, designed to engage the whole family in lifestyle changes by developing
knowledge and skills in physical activity and healthy eating, building skills in goal-setting
and self-monitoring, and creating a supportive home environment. Researchers will engage
community partners in formative research to adapt the current FI for rural Latino families.
Two parallel delivery methods of the FI will be developed and tested: 1) in-person group
setting at a community center (FI-IP) and 2) home-based delivered remotely with technology
(FI-RT). Both will be designed to address the unique social, cultural and environmental
factors facing rural Latino families. The FI-RT will take advantage of innovative modern
technology and e-Learning to increase program availability, accessibility and participation
in rural settings. Researchers will conduct a 3-arm randomized controlled trial (RCT) to
compare effectiveness of the two delivery approaches on weight loss (primary outcome) and
energy balance behaviors (secondary outcomes) among obese Latino parent-child pairs versus
control. The researchers will recruit 270 obese Latino adults (ages 21-65) with a child (ages
8-17) from three primary care practices in rural South Texas. These parent-child pairs will
be randomized to one of three arms stratified by clinic: 1) FI-IP (n=90); 2) FI-RT (n=90); or
3) control group (n=90). Primary specific aims are to: 1) Conduct community-engaged formative
studies to transform the existing FI into two unique delivery methods (FI-IP and FI-RT) for
use in a subsequent RCT in a rural Latino community; and 2) Conduct a RCT to evaluate the
comparative effectiveness of FI-IP and FI-RT to address weight loss (primary outcome) and
energy balance behaviors (secondary outcomes) among obese rural Latino adults compared with
adult participants in control group at immediate post intervention (3 months), after a
3-month maintenance program (6 months post randomization) and a 6-month follow-up (12 months
post randomization). A secondary aim is to examine the impact of FI-IP and FI-RT children's
weight and energy balance behaviors.

Obesity is a significant health threat in South Texas, a largely Latino region with one of
the most underserved, at-risk populations in the nation. Obesity can start in early childhood
and persist lifelong, setting the stage for disease.1-3 Because obesity impairs
health-related quality of life and billions are spent to manage obesity-related diseases,4
interventions to help obesity-affected families to adopt and maintain a healthier lifestyle
and achieve a healthy weight can have great individual and public health benefits.
Much has been learned about the efficacy and effectiveness of comprehensive healthy lifestyle
interventions to reduce obesity, but few studies have been translated into rural settings or
for Latinos.5 Barriers to implementing lifestyle interventions in rural settings include:
limited accessibility to health promotion programs, lack of health infrastructure,
transportation constraints, poverty, and low levels of health literacy.6,7 To address these
challenges, the proposed study will test two different methods of delivering a
family-focused, culturally appropriate healthy lifestyle intervention to obese Latino adults
and their families in rural South Texas. The family-focused intervention (FI), which builds
on evidence from studies of urban Latino families by PI Dr. Deborah Parra-Medina and her
South Texas-based research team, is a 12-week behavioral modification program grounded in the
social cognitive theory of behavior change. The intervention is designed to engage the whole
family in lifestyle changes by developing knowledge and skills in physical activity (PA) and
healthy eating, building skills in goal-setting and self-monitoring, and creating a
supportive environment at home.
Two parallel delivery methods of the FI will be developed and tested: 1) in-person group
setting at a community center (FI-IP) and 2) home-based delivered remotely with technology
(FI-RT). While both will be designed to address the unique social, cultural and environmental
factors facing rural Latino families, the latter takes advantage of innovative technology and
e-Learning to increase program availability, accessibility and program participation in rural
settings. The investigators will conduct a 3-arm randomized controlled trial to compare the
effectiveness of the two delivery approaches on weight loss (primary outcome) and energy
balance behaviors (secondary outcomes) among obese Latino parent-child pairs versus control.
The investigators will recruit 270 obese (BMI 30-39.9kg/m2) Latino adults (ages 21-65) with a
child (ages 8-17) from three primary care practices in rural South Texas. These 270
parent-child pairs will be randomized to one of three arms stratified by clinic: 1) FI-IP
(n=90); 2) FI-RT (n=90); or 3) control group (n=90). The primary specific aims of the study
are:
Aim 1: Conduct community-engaged formative studies to transform the existing family-focused
intervention (FI) into two unique delivery methods (FI-IP and FI-RT) for use in a subsequent
randomized controlled trial in a rural Latino community.
Aim 2: Conduct a randomized controlled trial to evaluate the comparative effectiveness of two
parallel delivery methods of family-focused intervention (FI-IP and FI-RT) to address weight
loss (primary outcome) and energy balance behaviors (secondary outcomes) among obese rural
Latino adults compared with control group adults at immediate post intervention (3 months
post randomization), again after a 3-month maintenance program (6 months post randomization)
and a 6-month follow-up (12 months post randomization).
• The investigators hypothesize that adult participants randomized to either FI-IP or FI-RT
will achieve greater weight loss and improved energy balance behaviors compared with adult
participants in the control group immediate post intervention (3 months post randomization),
after a 3-month maintenance program (6 months post randomization) and a 6-month follow-up (12
months post randomization).
The secondary aims are to examine:
- the impact of family-focused interventions on children's weight and energy balance
behaviors;
- the impact of the family-focused interventions on health-related quality of life
(HRQOL);8 and
- factors that facilitate or impede implementation and adherence to the two intervention
forms.
Findings from this comparative effective research will contribute to the evidence base to
inform clinical and health policy decisions in regard to weight management for obese patients
who may benefit from different approaches in intervention delivery.9 If successful, the
remote delivery approach holds great promise in improving healthcare to underserved
populations in rural and other remote locales.
