The purpose of this study was to examine the effects of a parent-focused, low-literacy, media-based intervention followed by motivational interviewing in a primary care setting on BMI, waist circumference, self-perception, family eating habits, and family activity habits in obese, Hispanic, school-aged children. A randomized controlled trial was conducted using 31 obese Hispanic, school-aged children between 6-11 years of age. There were 15 parent-child dyads in the experimental group and 16 parent-child dyads in the control group.
The study used a mixed methods approach, employing both quantitative and qualitative designs, implemented in two phases. The first phase of the study was the quantitative component in which parent-child dyads were randomly assigned into two groups. Pretest and post-tests measures of BMI-z scores, waist circumference, self-perception, and family eating and activity were obtained initially and two months later. The qualitative component utilized focus groups with parents of overweight Hispanic children to understand attitudes and feelings about the Internet and Internet support groups for helping with medical problems.
Data revealed changes in the experimental group in terms of BMI-z scores, waist circumference, and family eating habits. Decreases in BMI-z score was significant for the experimental group, p = .009 and changes in waist circumference was significant, p = .004. There was no significant change in the total child self-perception score, p = .10. However, there was a statistically significant t-test on physical appearance in the experimental group, p =.005. Regression analysis showed no relationship between BMI-z, waist circumference, family eating and activity with age, gender, or income.
The qualitative component suggested that technological knowledge and lifestyle may play a role in the use of technology in healthcare. Cultural factors need to be considered in designing educational program. The major barrier to Internet support groups was lack of time and knowledge.
Nurses need to consider technological skills, language, and cultural factors in designing interventions. Primary care settings may be an appropriate place for obesity counseling. Strategies to improve the use of Internet support groups are needed among parents of overweight, Hispanic, school-aged children. Implications for nursing education, nursing research, and clinical nursing are discussed.
