Objective: This study aimed to: 1) describe the current state of research activity/involvement and capacity among selected tertiary level government and private hospital dietitians; 2) identify factors associated with research capacity and involvement; and 3) develop policy recommendations to improve the current research activity/involvement towards evidence-based practice among hospital dietitians.

Methods: This is a cross-sectional descriptive study. A total of randomly selected 181 hospital dietitians from selected hospitals in Metro Manila completed a pre-tested structured self-administered questionnaire, which elicited the socio-demographic characteristics, research activity/involvement, research capacity, perception, attitude and knowledge (PAK) of the respondents.

Descriptive statistics were generated. Pearson Correlation was determined between socio-demographic characteristics and research activity/involvement score and research capacity score. Linear multiple regression analysis was conducted to test whether perceptions, attitudes and knowledge score are factors that predicted research activity/involvement and research capacity.

Results: No significant difference was observed in hospital dietitians' research capacity scores based on gender, age, educational attainment, hospital affiliation, and job description. Majority (97%) of the hospital dietitians had very little participation (10%) or involvement in any type of research activity/involvement. The significant factors that were predictive of research activity/involvement scores and research capacity scores were percent of time for research and hours per week devoted to research, respectively. Percent of time for research was significantly predictive of research knowledge of respondents.

Conclusion: The findings in this present study showed the research activity/involvement and capacity of hospital dietitians in Metro Manila were dismally low. The significant factors that were predictive of research activity/involvement scores and research capacity scores were percent of time for research and hours per week devoted to research, respectively. To support the development of research capacity and involvement of hospital dietitians, policy-makers and healthcare organizations can optimize capability-building strategies at the academic level, hospital dietitian level, and institutional level.

Objective: This study aimed to determine the energy density and satiety of meals based on the healthy food plate model for Filipino adults. Methods: Thirteen healthy adult volunteers consumed breakfast test meals consisting of 1 cup go food, ½ cup grow food and 1 ½ cups glow food, following the recommended proportions in the plate model. Energy density (kcal/g) of the test meals was calculated. Feelings of hunger and fullness were assessed with 100-mm visual analogue scales (VAS) at pre-prandial (0 minute) and at 30, 60, 90, 120, 150, 180, and 240 minutes postprandial. Ghrelin levels at 0, 30, 60, 120, 180, and 240 minutes were determined by radioimmunoassay (RIA). Results: The test meals had an average energy density of 0.83 kcal/g. Hunger and fullness scores gradually changed with time but hunger remained significantly lower and fullness significantly higher than the pre-prandial levels at 180 minutes postprandial. Ghrelin declined after intake of the test meals and stayed significantly lower than the pre-prandial level at 240 minutes postprandial (30.21 ± 4.58 pmol/L). Conclusion Meals following the recommendations in the healthy food plate model for Filipino adults have low energy density and its consumption sustained short-term satiety.
