Uptake of breast screening and associated factors among Hong Kong women aged ≥50 years: a population-based survey.

OBJECTIVE: To examine the uptake of breast screening and its associated factors among Hong Kong Chinese women aged ≥50 years. STUDY DESIGN: Cross-sectional population-based survey. METHODS: A sample of Hong Kong Chinese women was recruited through telephone random-digit dialling. The survey consisted of six sections: perceived health status, use of complementary medicine, uptake of breast screening, perceived susceptibility to cancer, family history of cancer and demographic data. The factors associated with uptake of breast screening were analysed using logistic regression analysis. RESULTS: In total, 1002 women completed the (anonymous) telephone survey. The mean age was 63.5 (standard deviation 10.6) years. The uptake rate of breast screening among Hong Kong Chinese women aged ≥50 years was 34%. The primary reasons for undertaking breast screening were as part of a regular medical check-up (74%), prompted by local signs and symptoms (11%) and a physician's recommendation (7%). Higher educational level, married or cohabiting, family history of cancer, frequent use of complementary therapies, regular visits to a doctor or Chinese herbalist, and the recommendation of a health professional were all independently and significantly associated with increased odds of having had a mammogram. CONCLUSIONS: This study provides community-based evidence of the need for public health policy to promote broader use of mammography services among this target population, with emphasis on the active involvement of health care professionals, through the development and implementation of appropriate evidence-based and resource-sensitive strategies.

Psychometric properties of the Chinese version of Sexual Function After Gynecologic Illness Scale (SFAGIS).

PURPOSE: This study aims to develop the Chinese version of the Sexual Function after Gynecologic Illness Scale (SFAGIS) and to establish its psychometric properties in Hong Kong Chinese patients with gynecological cancer. METHODS: A Chinese version of SFAGIS was developed using the Brislin model of translation and guidelines for cross-cultural adaptation of scales. The content validity and semantic equivalence were assessed by an expert panel. The translated version of SFAGIS was administered to 150 Hong Kong Chinese women with gynecological cancer to test the scale's psychometric properties and to assess its feasibility. The convergent validity of the Chinese scale was tested by correlating it with the Chinese version of the sex relations subscale of the Psychosocial Adjustment to Illness Scale Self-Report (PAIS-SR). RESULTS: The average completion time for the Chinese SFAGIS was 16.2 ± 6.6 min. The internal consistency of the Chinese SFAGIS was 0.93. Test-retest reliability was also high with an interclass correlation coefficient 0.76. A Pearson product-moment correlation found strong correlations among the Chinese SFAGIS and the Chinese version of the sex relations subscale of the PAIS-SR, indicating that both scales measure the same as or has a similar construct. CONCLUSIONS: The Chinese version of SFAGIS is a reliable and valid instrument which can be used in clinical practice and research for assessing sexual function problems in Chinese patients with gynecological cancer and to identify those in need of attention.

Associations of uric acid and gamma-glutamyltransferase (GGT) with obesity and components of metabolic syndrome in children and adolescents.

BACKGROUND: The combined effect of uric acid, gamma-glutamyltransferase (GGT) and cardiovascular risk factors clustering in the youth remains under-explored. OBJECTIVE: The objective of this study was to examine the association between uric acid, GGT, obesity and the individual components of metabolic syndrome in children and adolescents. METHODS: We performed a cross-sectional observational study of 2067 children and adolescents (875 boys and 1192 girls) aged 6-20 years who were healthy volunteers and were recruited from primary and secondary schools in Hong Kong between 2007 and 2008. Subjects were divided into two strata (75th percentile as cut-off) for comparison between odds of cardiovascular risk factors. RESULTS: After adjustment by multivariable logistic regression, subjects in upper stratum, i.e., >75th percentile, of either serum uric acid or GGT levels were associated with obesity, low high-density lipoprotein cholesterol (HDL-C) level and high blood pressure (adjusted odds ratios [AOR] ranged from 1.63 to 5.82, all P < 0.005) compared with those in the lower stratum. There were combined effect for upper stratum of both uric acid and GGT in the association with obesity, low HDL-C and high blood pressure (AOR ranged from 2.60 to 10.69, all P < 0.05) after adjustment for age, sex and body mass index z-score (except for obesity status) as well as body height (for high blood pressure). CONCLUSION: Uric acid and GGT have combined effect in association with obesity and other cardiovascular risk factors in children and adolescents.

Quality-of-life among head and neck cancer survivors at one year after treatment--a systematic review.

BACKGROUND: The importance of quality-of-life (QoL) research has been recognised over the past two decades in patients with head and neck (H&N) cancer. The aims of this systematic review are to evaluate the QoL status of H&N cancer survivors one year after treatment and to identify the determinants affecting their QoL. METHODS: Pubmed, Medline, Scopus, Sciencedirect and CINAHL (2000-2011) were searched for relevant studies, and two of the present authors assessed their methodological quality. The characteristics and main findings of the studies were extracted and reported. RESULTS: Thirty-seven studies met the inclusion criteria, and the methodological quality of the majority was moderate to high. While patients of the group in question recover their global QoL by 12 months after treatment, a number of outstanding issues persist - deterioration in physical functioning, fatigue, xerostomia and sticky saliva. Age, cancer site, stage of disease, social support, smoking, feeding tube placement and alcohol consumption are the significant determinants of QoL at 12 months, while gender has little or no influence. CONCLUSIONS: Regular assessments should be carried out to monitor physical functioning, degree of fatigue, xerostomia and sticky saliva. Further research is required to develop appropriate and effective interventions to deal with these issues, and thus to promote the patients' QoL.

Colorectal cancer screening behaviour and associated factors among Chinese aged 50 and above in Hong Kong - a population-based survey.

PURPOSE: This study reports the uptake rate of colorectal cancer screening among Chinese people aged 50 or above and the identified factors associated with the likelihood of undergoing such screening. METHODS: A cross-sectional population-based telephone survey was conducted in Hong Kong during the period 2 to 28 May 2007. The survey covered demographics, perceived health status and susceptibility to cancer, utilisation of complementary medicine, family history of cancer and cancer screening behaviour. RESULTS: The survey was completed by 2004 Hong Kong Chinese residents aged 50 or older (response rate = 66.6%). The uptake rate of a fecal occult blood test and a colonoscopy was 12% and 19% respectively. Factors associated with colorectal cancer screening behaviour included: male participants, ex-smokers, with cancer or other serious disease, a family history of cancer, perceived health status fair or poor, regular visits to a doctor to look after health, and utilisation of complementary medicine. CONCLUSIONS: The uptake rate of this study population was low though an increasing trend did appear. Heath education and promotion programmes may focus on these identified factors to facilitate colorectal cancer screening in a Chinese population.

Fatigue patterns in Chinese patients receiving radiotherapy.

Fatigue has been reported as the most frequently occurring symptom in cancer patients receiving chemoradiotherapy. The purpose of the current descriptive study was to explore the pattern, associated factors, and experience of fatigue in Chinese cancer patients receiving radiotherapy. Twenty-seven subjects from an out patient clinic of a university hospital in Hong Kong participated in the study. They were asked to complete three times daily (morning, afternoon and evening) a diary over a period of two weeks from the beginning of their therapy. The diary incorporated a 10-cm horizontal visual analogue scale (VAS) for measuring fatigue intensity. Further, the Chinese version of the fatigue subscale of the Profile of Mood States was completed before the radiotherapy, at the end of the first week post-treatment, and at the end of the second week. Most patients (44-80.8%) undergoing radiotherapy in this study experienced fatigue at some point during their treatment. The pattern of fatigue was that of repeated curves, with higher levels observed in the afternoons and evenings, and at the end of the first week or the end of the second week. Qualitative data indicated the universal sensations of fatigue and also some culturally specific descriptors. A variety of methods were used by the patients to cope with their fatigue but the effects of such methods were not always positive. It is important for clinical practice to assess the individual patterns and perceptions of fatigue, identify those patients at risk for developing fatigue and initiate interventions to combat fatigue.
