Abstract:Filipino adolescents are one of the most overweight ethnic groups in Hawai‘i. With
limited research on health behaviors of Filipino adolescents (age 10-19), it is important to have
research that focuses on decreasing health disparities in this adolescent population. This study
aims to fill the gap on Filipino adolescent physical activity (PA) and fruit and vegetable (FV)
social cognitive and behaviors using the Social Cognitive Theory through peer influence to
create positive health behaviors, examine Multiple Health Behavior Change (MHBC) and if peer
educators (PEs) change their health behaviors through teaching a health curriculum. The
Waipahu Health Action Research and Training (HART) project is a quasi-experimental design
peer-influence study based at Waipahu High School (WHS). It includes three manuscripts: 1) use
peer influence to increase PA and FV social cognitive and behavior variables in Filipino
adolescents, 2) examine transfer and compensation effects of PA, FV consumption, and
sedentary behavior (SB) in Filipino adolescents and 3) examine if PEs increase their PA and FV
social cognitive and behavior variables through teaching a health curriculum. Participants were
all Filipino students from nine WHS health classes (5 intervention, 4 control). PEs were Filipino
senior health capstone class at WHS. Findings suggest a peer-led PA and nutrition curriculum
can benefit participants and PEs in terms of PA social cognitive and behavior variables. Multiple
regression analysis showed for the intervention group follow-up PA knowledge is 0.62 units
(SE=0.15, p<0.01) higher and follow-up Moderate-Vigorous PA (MPVA) is 20.04 min/week
(SE=6.13, p<0.01) higher than the control group. A trend towards follow-up PA enjoyment for
the intervention group being 0.41units (SE=0.23, p=0.09) higher than the control group was seen.
PA knowledge had a significant interaction for AT RISK (Stage of Change pre-contemplation,
contemplation and preparation) (F(1, 65)=6.69, p<0.01). A trend towards a transfer effect of PA
for Low vs. High SB (F(1, 76)=3.76, p=0.06) was seen. PEs increased their PA stage of change
(F(1, 18) =5.51, p=0.03) and MVPA (F(1, 18)=7.44, p<0.01) through teaching the HART
curriculum. Given currently limited research on Filipino adolescents’ health behaviors, this
dissertation adds to the literature and gives guidance for future research.
