Linking cohort-based data with electronic health records: a proof-of-concept methodological study in Hong Kong.

OBJECTIVES: Data linkage of cohort-based data and electronic health records (EHRs) has been practised in many countries, but in Hong Kong there is still a lack of such research. To expand the use of multisource data, we aimed to identify a feasible way of linking two cohorts with EHRs in Hong Kong. METHODS: Participants in the 'Children of 1997' birth cohort and the Chinese Early Development Instrument (CEDI) cohort were separated into several batches. The Hong Kong Identity Card Numbers (HKIDs) of each batch were then uploaded to the Hong Kong Clinical Data Analysis and Reporting System (CDARS) to retrieve EHRs. Within the same batch, each participant has a unique combination of date of birth and sex which can then be used for exact matching, as no HKID will be returned from CDARS. Raw data collected for the two cohorts were checked for the mismatched cases. After the matching, we conducted a simple descriptive analysis of attention deficit hyperactivity disorder (ADHD) information collected in the CEDI cohort via the Strengths and Weaknesses of ADHD Symptoms and Normal Behaviour Scale (SWAN) and EHRs. RESULTS: In total, 3473 and 910 HKIDs in the birth cohort and CEDI cohort were separated into 44 and 5 batches, respectively, and then submitted to the CDARS, with 100% and 97% being valid HKIDs respectively. The match rates were confirmed to be 100% and 99.75% after checking the cohort data. From our illustration using the ADHD information in the CEDI cohort, 36 (4.47%) individuals had ADHD-Combined score over the clinical cut-off in the SWAN survey, and 68 (8.31%) individuals had ADHD records in EHRs. CONCLUSIONS: Using date of birth and sex as identifiable variables, we were able to link the cohort data and EHRs with high match rates. This method will assist in the generation of databases for future multidisciplinary research using both cohort data and EHRs

The Role of Nutrition in Sucessful Aging

Optimal body weight values associated with good health outcomes in elderly people aged 70 years and over differ from values for the general adult population, and the emphasis is on weight maintenance and avoidance of weight loss. Dietary patterns for maintaining cardiovascular and bone health include dietary patterns such as the Mediterranean Diet, restriction of saturated fats and salt, adequate protein, calcium, vitamin D and C intake. Outcomes of particular importance for older populations include maintenance of mobility and independence, and nutrition is an important factor in maintaining muscle mass and function. Good unique to Asia that are beneficial for health include soya beans, tea, and possibly black rice

A randomized controlled trial of mental imagery augment generalization of learning in acute poststroke patients

Background and purpose-: Our previous studies demonstrated that mental imagery intervention enhanced poststroke patients relearning daily task performance. This study aimed to test the efficacy of mental imagery for promoting generalization of the task skills learned in a training environment to trained and untrained tasks carried out in a novel environment. METHODS-: Thirty-five acute poststroke patients were randomly assigned to the mental imagery (MI; n=18) or conventional functional rehabilitation (FR; n=17) group. The MI intervention was 3-week standardized practices and daily tasks using the chunking-regulation-rehearsal strategies. Outcome measurements were the performances on trained and untrained tasks in the training and novel environments. RESULTS-: The MI patients showed significantly better performances on 4 of 5 trained tasks (P=0.001 to 0.026) versus only 1 task in the FR patients (P=0.021). The MI patients also outperformed their FR counterpart on the 3 (of 5) (P=0.025 to 0.049) trained and 2 (of 3) untrained tasks (P=0.042 to 0.045) carried out in the novel environment. CONCLUSIONS-: The mental imagery intervention was useful for improving patients' ability on performing the tasks which they did not previously trained on and in places different from the training environments. These involved generalization of the skills learned at the task performance level. Our findings are limited to poststoke patients who share similar characteristics with those in this study. © 2009 American Heart Association, Inc.link_to_OA_fulltex

Risk factors for child physical abuse and neglect among Chinese young mothers

Although studies have reported a linkage between young pregnancy and child maltreatment risk, it is still unclear about what factors place young mothers at greater risk of maltreating their child in Chinese context. Based on the socio-ecological model, risk factors in 4 domains: family background/structure, maternal stressors, mother-child interaction, and child behavioral issue in relation to physical assault, neglect, both physical assault and neglect, and either physical assault or neglect among Chinese young mothers in Hong Kong were assessed. 392 young mothers were recruited from an integrated supportive program for young mothers. The mean age of mothers at delivery was 21.8 (SD = 3.0) and 52.3% were married. Individual risk factors and cumulative risk domains related to different child maltreatment groups were examined. Our results show both overlapping and unique risk factors across the domains associated with physical assault and neglect. Further, young families exposed to higher number of risk domains show higher rates for physical assault and neglect, co-occurrence of physical assault and neglect, and either form of maltreatment. In addition, various risk domains were found to be particularly important for different forms of maltreatment: family background/structure domain was found to be an important risk domain for neglect; mother-child interaction domain for both physical assault and neglect; family background/structure and maternal stressors domains for either physical assault or neglect. Closer examination of a subgroup of adolescent mothers aged 18 and below shows that family background/structure was an important risk domain for this group.Department of Applied Social Science
