Description
Two studies were conducted to test a model to predict healthy lifestyle behaviors, physical activity, and body mass index (BMI) in Taiwanese adolescents by assessing their physical activity and nutrition knowledge, healthy lifestyle beliefs, and perceived difficulty in performing healthy lifestyle behaviors. The study drew upon cognitive behavioral theory to develop this study. The pilot study aimed to test and evaluate psychometric properties of eight Chinese-version scales. The total sample for the pilot study included 186 participants from two middle schools in Taiwan. The mean age was 13.19 for boys and 13.79 for girls. Most scales including Beck Youth Inventory self-concept, Beck Youth Inventory depression, Beck Youth Inventory anxiety, healthy lifestyle beliefs, perceived difficulty, and healthy lifestyle behaviors scales Cronbach alpha were above .90. The Cronbach alpha for the nutrition knowledge and the activity knowledge scale were .86 and .70, respectively. For the primary study, descriptive statistics were used to describe sample characteristics, and path analysis was used to test a model predicting BMI in Taiwanese adolescents. The total sample included 453 participants from two middle schools in Taiwan. The mean age of sample was 13.42 years; 47.5% (n = 215) were males. The mean BMI was 21.83 for boys and 19.84 for girls. The BMI for both boys and girls was within normal range. For path analysis, the chi-square was 426.82 (df = 22, p < .01). The CFI of .62 and the RMSEA of .20 suggested that the model had less than an adequate fit (Hu & Bentler, 1999). For alternative model, dropping the variable of gender from the model, the results indicated that it in fact was an adequate fit to the data (chi-square (23, 453) =33.75, p> .05; CFI= .98; RMSEA= .03). As expected, the results suggested that adolescents who reported higher healthy lifestyle beliefs had more healthy lifestyle behaviors. Furthermore, adolescents who perceived more difficulty in performing healthy lifestyle behaviors engaged in fewer healthy lifestyle behaviors and less physical activity. The findings suggested that adolescents' higher healthy lifestyle beliefs were positively associated with their healthy lifestyle behaviors.

Description
Late preterm infants (LPIs), born between 34 and 37 weeks gestation, are at risk for a myriad of health conditions related to neuro-muscular and physiologic immaturity. However, relative stability allow many of these infants to avoid care in specialty nurseries and discharge home with their mothers after birth. Due to underlying immaturity, feeding difficulty is the most common issue LPIs experience, resulting in early breastfeeding cessation, increased risk for secondary diagnoses, and hospital readmission. The purpose of this study was to assess early breastfeeding behavior of LPIs, including testing inter-rater reliability of an assessment tool and the feeding patterns of infants over time. An extensive review of breastfeeding assessment tools resulted in the selection of the Premature Infant Breastfeeding Behavior Scale (PIBBS) based on its reliability and validity in the preterm infant population. A convenience sample of LPI dyads was recruited and used to conduct inter-rater reliability testing of PIBBS. A longitudinal one-group non-experimental study was used for observational follow-up. A strong statistical agreement of PIBBS scores occurred between mothers and a healthcare professional (Cohen’s kappa values of items ranged from .776 to 1.000, p = <.001). Participants continued using the PIBBS tool after hospital discharge until their infants expected due dates (40 weeks adjusted age). T-test analyses were conducted to examine changes in scores over time indicating increase in item scores (p = .003 - .193). PIBBS appears to be a valid and reliable tool to assess breastfeeding among LPI dyads. Incorporation of PIBBS into a comprehensive plan of care could better support and protect breastfeeding among the LPI population.

Description
This body of research sought to explore relationships between cognitive function and physical activity (PA), sedentary behavior (SB), and sleep, independently and in conjunction, in mid-life to older adults with no known cognitive impairment. Aging is associated with cognitive decline, and lifestyle behaviors such as PA, SB, and sleep, may mitigate this decline. First, a systematic review and meta-analysis was conducted to examine the effect of aerobic PA interventions on memory and executive function in sedentary adults. Second, a longitudinal study was conducted to examine the association between SB and odds of incident cognitive impairment, and SB and cognitive decline in older adults. Last, a cross-sectional study was conducted to examine the joint associations between different levels of sleep with levels of PA, and sleep with levels of sedentary time on memory and executive function. This body of research provided evidence to support the association between aerobic PA and improved cognitive function, SB and incident cognitive impairment and cognitive function declines, and the joint association of sleep and different levels of PA and ST on cognitive function by hypertension status.
