Abstract/Description:
Problem: In recent years, childhood obesity has increased to epidemic proportions across the United States (U.S.) in parallel with adult obesity, which often reflects poor dietary choices and bad nutritional habits. Purpose: The primary purpose of this study was to examine the effects of parent and adolescent nutrition literacy expressed as nutrition knowledge and skills, with total household income and parent level of education, as predictors of weight status in adolescents that live in a Florida community. The secondary purpose of this study was to examine the implications for nutrition literacy levels within parent/adolescent dyads to identify public health initiatives aimed at adult and adolescent populations.Methods: A descriptive, correlational design was used to collect data from a convenience sample of 110 parent-adolescent dyads recruited from a free physical exam event hosted by a local health care facility. Three instruments were completed by each dyad: 1) demographic survey, 2) Nutrition Literacy Survey (NLS; knowledge), and 3) Newest Vital Sign (NVS; skills). Physiologic measurements for the study included anthropometric measurement of the adolescent child's height (cm) and weight (kg) without shoes and BMI scores were calculated. In addition to actual value, BMI was categorized as low/normal and overweight/obese for analysis. Paired t-tests were used to compare means for the NLS and NVS survey in parent-adolescent dyads. Bivariate correlation scores were computed between the two variables of parent/adolescent NLS and NVS scores. Lastly, regression models for examining adolescent BMI were compared with the independent variables of the study.Results: The sample of adult participants (n =110) comprised males (n = 30, 27%) and females (n =80, 73%) ranging in age from 34 to 55 years (M= 41.9, SD= 4.77). Adolescent participants (n=110) comprised males (n = 61, 55%) and females (n = 49, 45%) ranging in age from 13 to 17 years (M = 15.1, SD = 1.43). Adolescent male participants had higher BMI (27 + 3.48) than females (24 + 2.90), t (108) = 4.83, (p = (<) .001). Adolescent males were categorized more overweight/obese than females (67.2% versus 24.5%). The parent NLS mean score (M=19) indicated low overall levels of general nutrition knowledge whereas the adolescent NLS mean score (M=21.7) demonstrated greater aptitude for nutrition knowledge than parent scores. The parent NVS mean score (M=4.1) suggested adequate levels of nutrition skills. Likewise, the adolescent NVS mean score (M= 4.1) suggested adequate nutrition skills, similar to scores in the adult population. Spearman rho correlations yielded positive correlations between parent/adolescent nutrition knowledge, (rs = .224, p = .019), and parents' nutrition knowledge and skills (rs = .596, p (<) .001). Positive correlations were also noted between adolescents' nutrition knowledge and parents' nutrition skills (rs = .257, p = .007) and adolescents' nutrition knowledge and nutrition skills (rs = .260. p = .006). Three regression models were calculated to examine adolescent BMI with the independent variables of the study. Analysis of regression coefficients for each model indicated that none of the variables demonstrated significance as a predictor of adolescent BMI.Discussion/Implications: The results of the study suggest that parents and adolescents may have similar amounts of nutrition literacy when examining the constructs of nutrition knowledge and skills; however, BMI is not solely dependent on these skill sets. Examination of the factors that influence parents and adolescent children's weight status are important elements in shaping families adoption of sound dietary habits and improving health outcomes.
