Objective This study was conducted to examine whether an educational videotape might change peoples' attitudes toward participating in future cohort studies by a prospective randomized controlled trial. Methods The participants were recruited from the residents of Kamogawa-city (139 at a health promotion festival, 54 from a nursery care study class, 53 from an elderly class, and 9 individuals who had not attended a health checkup for more than 10 years). All participants were randomized into a control group and an intervention group, and were asked to fill out a questionnaire designed to evaluate attitudes toward participating in future cohort studies. Those in the intervention group, however, were also asked to watch a videotape, produced by the authors to explain the objectives, significance, and security policies of a cohort study planned to be conducted in the same city, before completing the questionnaire. Results In the intervention group, 44% (54/123) showed a positive attitude to future participation, while the figure was only 25% (31/122) in the control group (Cochran-Mantel-Haenszel χ2: P=0.0025). Conclusion The videotape proved to be a useful tool for informing the general public about the nature of cohort studies and to increasing probable participation.
Objective The purpose of this study was to identify significant factors for loneliness in older adults in Nepal. Methods The subjects (N=195) were members of the Newar caste/ethnicity, aged 60 years and above (mean(±SD) 68.81(±7.69) years and 52% male) and living in Katmandu City. Data were collected by face-to-face interview using a three-item loneliness scale, developed based on the University of California at Los Angeles (UCLA) Loneliness Scale and prepared with a translation and back translation technique from English into Nepalese. The data were analyzed using logistic regression analyses. Results More than two-thirds of Newar elderly experience some type of loneliness. A statistically significant correlation was found between feelings of loneliness and age, sex, household status, total family size, network size, social participation, self-reported health, chronic health problems, working status, instrumental activities of daily living (IADL), and perceived economic satisfaction. Results of logistic regression analyses showed age, network size, and perceived economic satisfaction to be significant factors for loneliness. Conclusion Loneliness is an important public health issue, predicting low quality of life among older adults. The present results indicate many elderly Nepalese experience some form of loneliness, with age, network size and perceived economic satisfaction as significant factors. However, this result may not be generalized to the greater population of Nepalese older adults and the external validity of the UCLA Loneliness Scale is an important criterion to examine in future research.
