Association between Screen Viewing Duration and Sleep Duration, Sleep Quality, and Excessive Daytime Sleepiness among Adolescents in Hong Kong

Screen viewing is considered to have adverse impacts on the sleep of adolescents. Although there has been a considerable amount of research on the association between screen viewing and sleep, most studies have focused on specific types of screen viewing devices such as televisions and computers. The present study investigated the duration with which currently prevalent screen viewing devices (including televisions, personal computers, mobile phones, and portable video devices) are viewed in relation to sleep duration, sleep quality, and daytime sleepiness among Hong Kong adolescents (N = 762). Television and computer viewing remain prevalent, but were not correlated with sleep variables. Mobile phone viewing was correlated with all sleep variables, while portable video device viewing was shown to be correlated only with daytime sleepiness. The results demonstrated a trend of increase in the prevalence and types of screen viewing and their effects on the sleep patterns of adolescents.

Parental responses to health care services for children with chronic conditions and their families: a comparison between Hong Kong and Scotland

Families caring for a chronically-ill child are known to experience a significant degree of stress that often is not fully understood by health professionals. The purpose of this study was to examine, cross culturally, the experience of families caring for children with chronic conditions both in terms of the impact on their lives and the nature of the support received. The responsibility of caring for a child with a chronic condition had considerable impact on family life in both groups, with the disturbance to harmony possibly being felt more keenly in the Hong Kong group. Effective communication with parents was seen in both countries as key for effective practice. Expectations of health services differed between cultures. Implications can be drawn for the design of future health services addressing the specific health needs of families with children with chronic illness.

Parenting approaches and digital technology use of preschool age children in a Chinese community

BackgroundYoung children are using digital technology (DT) devices anytime and anywhere, especially with the invention of smart phones and the replacement of desktop computers with digital tablets. Although research has shown that parents play an important role in fostering and supporting preschoolers’ developing maturity and decisions about DT use, and in protecting them from potential risk due to excessive DT exposure, there have been limited studies conducted in Hong Kong focusing on parent-child DT use. This study had three objectives: 1) to explore parental use of DTs with their preschool children; 2) to identify the DT content that associated with child behavioral problems; and 3) to investigate the relationships between approaches adopted by parents to control children’s DT use and related preschooler behavioral problems.MethodsThis exploratory quantitative study was conducted in Hong Kong with 202 parents or guardians of preschool children between the ages of 3 and 6 attending kindergarten. The questionnaire was focused on four aspects, including 1) participants’ demographics; 2) pattern of DT use; 3) parenting approach to manage the child’s DT use; and 4) child behavioral and health problems related to DT use. Multiple regression analysis was adopted as the main data analysis method for identifying the DT or parental approach-related predictors of the preschooler behavioral problems.ResultsIn the multiple linear regression model, the ‘restrictive approach score’ was the only predictor among the three parental approaches (B:1.66, 95% CI: [0.21, 3.11], p < 0.05). Moreover, the viewing of antisocial behavior cartoons by children also significantly increased the tendency of children to have behavioral problem (B:3.84, 95% CI: [1.66, 6.02], p < 0.01).ConclusionsSince preschool children’s cognitive and functional abilities are still in the developmental stage, parents play a crucial role in fostering appropriate and safe DT use. It is suggested that parents practice a combination of restrictive, instructive and co-using approaches, rather than a predominately restrictive approach, to facilitate their child’s growth and development. Further studies are needed to explore the parent-child relationship and parents’ self-efficacy when managing the parent-child DT use, to develop strategies to guide children in healthy DT use.

The influence of weather on health-related help-seeking behavior of senior citizens in Hong Kong.

It is believed that extreme hot and cold weather has a negative impact on general health conditions. Much research focuses on mortality, but there is relatively little community health research. This study is aimed at identifying high-risk groups who are sensitive to extreme weather conditions, in particular, very hot and cold days, through an analysis of the health-related help-seeking patterns of over 60,000 Personal Emergency Link (PE-link) users in Hong Kong relative to weather conditions. In the study, 1,659,716 PE-link calls to the help center were analyzed. Results showed that females, older elderly, people who did not live alone, non-subsidized (relatively high-income) users, and those without medical histories of heart disease, hypertension, stroke, and diabetes were more sensitive to extreme weather condition. The results suggest that using official government weather forecast reports to predict health-related help-seeking behavior is feasible. An evidence-based strategic plan could be formulated by using a method similar to that used in this study to identify high-risk groups. Preventive measures could be established for protecting the target groups when extreme weather conditions are forecasted.

Participatory action research: Involving students in parent education

Competition for scarce clinical placements has increased requiring new and innovative models to be developed to meet the growing need. A participatory action research project was used to provide a community nursing clinical experience of involvement in parent education. Nine Hong Kong nursing students self-selected to participate in the project to implement a parenting program called Parenting Young Children in a Digital World. Three project cycles were used: needs identification, skills development and program implementation. Students were fully involved in each cycles planning, action and reflection phase. Qualitative and quantitative data were collected to inform the project. The overall outcome of the project was the provision of a rich and viable clinical placement experience that created significant learning opportunities for the students and researchers. This paper will explore the students participation in this PAR project as an innovative clinical practice opportunity.

Correlates of Protective Motivation Theory (PMT) to adolescents' drug use intention.

Early onset and increasing proliferation of illicit adolescent drug-use poses a global health concern. This study aimed to examine the correlation between Protective Motivation Theory (PMT) measures and the intention to use drugs among adolescents. An exploratory quantitative correlation design and convenience sampling were adopted. A total of 318 students completed a self-reported questionnaire that solicited information related to their demographics and activities, measures of threat appraisal and coping appraisal, and the intention to use drugs. Logistic regression analysis showed that intrinsic and extrinsic rewards were significant predictors of intention. The odds ratios were equal to 2.90 (p < 0.05) and 8.04 (p < 0.001), respectively. The logistic regression model analysis resulted in a high Nagelkerke R2 of 0.49, which suggests that PMT related measures could be used in predicting drug use intention among adolescents. Further research should be conducted with non-school adolescents to confirm the application.

Beliefs and knowledge about vaccination against AH1N1pdm09 infection and uptake factors among Chinese parents.

Vaccination against AH1N1pdm09 infection (human swine infection, HSI) is an effective measure of preventing pandemic infection, especially for high-risk groups like children between the ages of 6 months and 6 years. This study used a cross-sectional correlation design and aimed to identify predicting factors of parental acceptance of the HSI vaccine (HSIV) and uptake of the vaccination by their preschool-aged children in Hong Kong. A total of 250 parents were recruited from four randomly selected kindergartens. A self-administered questionnaire based on the health belief framework was used for data collection. The results showed that a number of factors significantly affected the tendency toward new vaccination uptake; these factors included parental age, HSI vaccination history of the children in their family, preferable price of the vaccine, perceived severity, perceived benefits, perceived barriers, and motivating factors for taking new vaccines. Using these factors, a logistic regression model with a high Nagelkerke R2 of 0.63 was generated to explain vaccination acceptance. A strong correlation between parental acceptance of new vaccinations and the motivating factors of vaccination uptake was found, which indicates the importance of involving parents in policy implementation for any new vaccination schemes. Overall, in order to fight against pandemics and enhance vaccination acceptance, it is essential for the government to understand the above factors determining parental acceptance of new vaccinations for their preschool-aged children.

The Association of Pet Ownership and Attachment with Perceived Stress among Chinese Adults

ABSTRACT Pet ownership is associated with both positive and negative emotions. Given that not everyone responds to pet care in a stressful way, perceptions of companion animals may play a role in how owners respond to them. In this study, we explored the relationship between pet ownership and perceived stress among Chinese pet owners. We also examined the effect of care practices and perceptions of pets on perceived stress. A total of 288 Hong Kong Chinese, adult pet owners, aged 18 to 70 years, were recruited. Participants were surveyed using a self-administered questionnaire covering demographics, pet ownership background, pet attachment, and perceived stress. Regression analyses were performed to examine pet attachment in different demographic groups and its relationship with perceived stress. Moderation and mediation analyses were performed to elucidate their underlying mechanisms. After adjusting for demographics and pet ownership background, greater attachment to a pet was associated with lower stress in owners. The perception of pets as family members minimized the stressful burden of pet care. More time spent caring for a pet increased attachment to that animal which in turn reduced stress in owners. The findings suggest attachment to companion animals and the perception of them as family members can help manage and reduce stress in owners.

Brief take-home laughter yoga practice (B-TLYP): impact on multi-dimensional affects among Chinese adults in Hong Kong

ABSTRACT Objective: To examine the impact of a brief take-home laughter yoga practice (B-TLYP) on the multi-dimensional affects among Chinese adults in Hong Kong. Method: The intervention consisted of a one-hour workshop and 7-day home practice on laughter yoga exercises. Thirty-six adults (mean age: 48.3 years) joined the intervention and completed questionnaires on demographics and affect scales. Positive affect (PA) and negative affect (NA) were measured by the Positive and Negative Affect Scale (PANAS) at baseline, immediately and one week after the intervention. Repeated measure ANOVA was used to examine differences in PANAS scores across time. Results: The mean score of PANAS PA subscale showed an increasing trend across time, whereas there was no difference in the mean score of PANAS NA subscale. Discussion: This study provides preliminary support for the benefits of B-TLYP on adults’ positive affect.

Characteristics of influential peers in the eyes of secondary school students: a mixed method study

Aim It is the aim of this study to explore the characteristics of influential peers identified by schoolmates, and the mechanism by which they exert their influence on their peers. BACKGROUND Adolescent crowds are a salient influence on the health-risk behaviors of peers, contributing to adolescent substance use such as drinking alcohol, smoking cigarettes, and taking drugs. METHODS A mixed method study. Three schools granted us access to students and those who had been nominated as influential by their peers. The students were asked to nominate and indicated the characteristics of peers whom they considered influential in a quantitative study. Those peers whom they considered influential were invited to take part in focus group interviews. A total of six focus group interviews were conducted, comprised of two groups from each school, with an average of seven participants in each group. Findings Students considered caring and friendliness (91.0%), being a buddy (88.5%), and entertaining/humor (86.8%) as the top three characteristics of influential peers. The interviews revealed that the students believed that they are influential because of their cheerfulness and humor, considerateness, ability to communicate, popularity and sociability, sincerity and trustworthiness, and because they possess the characteristics of a leader. They also believed that their power to influence came about through their helpfulness, accommodation, and the closeness of their relationships. Their influence was manifested in both positive and negative ways on the academic pursuits and health-risk behaviors of their peers. In order to engage at-risk students in health promotion programs, it is important to identify their influential peers, and to understand how adolescent friends may help one another to resist behaviors that pose a risk to their health.
