Relationship between Chinese medicine dietary patterns and the incidence of breast cancer in Chinese women in Hong Kong: a retrospective cross-sectional survey.

ABSTRACT:

Background

This retrospective cross-sectional study aimed to investigate the relationship between Chinese medicine (CM) dietary patterns (hot, neutral, and cold) and the incidence of breast cancer among Chinese women in Hong Kong.

Methods

Breast cancer cases (n = 202) and healthy controls (n = 202) were matched according to demographics. Chinese women residing in Hong Kong for the past 7 years were recruited by media advertisements (e.g., via newspapers, radio, and posters). The control participants were recruited by convenience sampling from health workshops held in clinics and communities of 15 districts of Hong Kong. After completing test-retest reliability, all participants were asked to complete diet pattern questionnaires about their food preferences and dietary patterns. The Student's unpaired t test, Chi square test, and logistic regression were conducted using SPSS software.

Results

Three major CM dietary patterns were identified: hot, neutral, and cold. The participants with breast cancer exhibited a stronger preference for hot food than the control group (Chi square test, P < 0.001). A higher frequency of breast cancer was associated with a higher frequency of dining out for breakfast (4-5 times per week, Chi square test, P = 0.015; 6-7 times per week, Chi square test, P < 0.001) and lunch (4-5 times per week, Chi square test, P < 0.001; 6-7 times per week, Chi square test, P = 0.006). The participants with no history of breast cancer consumed CM supplements and Guangdong soups (1-2 times per week, Chi square test, P = 0.05; >3 times per week, Chi square test, P < 0.001) more frequently than those with breast cancer.

Conclusions

Non-breast cancer participants adopted a neutral (healthy and balanced) dietary pattern, and consumed CM supplements and Guangdong soups more frequently.

Project description:BackgroundTraditional Chinese Medicine Constitution (TCMC) refers to an integrated, metastable and natural specialty of individual in morphosis, physiological functions and psychological conditions. It is formed on the basis of innate and acquired endowments in the human life process, which can be divided into normal constitution and unbalanced ones. The aim of this study was to investigate the distribution of TCMCs of Chinese women in Hong Kong and its acquired influencing factors.MethodsLocal Chinese women between 30 to 65 years old, were recruited from 18 districts of Hong Kong (n=944), and were assessed using the Traditional Chinese Medicine Physical Constitution Scale for their TCMC types. Social-demographic, reproductive, lifestyle, systemic health and emotional status information were collected through structured questionnaire. The associations between different independent factors and each TCMC type, as well as the complex unbalanced TCMC types were tested individually. Significant factors related to unbalanced TCMC types were identified in final models using multiple factor analysis.ResultsA total of 764 (80.9%) participants were diagnosed with unbalanced TCMCs. The most common TCMC type was Qi-deficiency constitution (53.9%), followed by Phlegm-wetness (38.9%), Yang-deficiency (38.2%), Yin-deficiency (35.5), Blood-stasis (35.4) and Qi-depressed (31%) constitution. Six hundred and eleven participants (64.7%) had at least two types of combined and unbalanced constitutions. Stepwise logistic analysis indicated that poor systemic health condition (OR, 1.76-2.89), negative emotions (OR=1.39), overweight (OR=1.58), high educational level (OR=1.18) and mental work (OR=1.44) were significantly positively correlated with certain unbalanced TCMCs. Meanwhile, aging (OR, 0.59-0.73), exercise habit (OR, 0.61-0.79) and reproductive history (OR=0.72) showed inverse associations with unbalanced constitutions. In addition, systemic health condition and emotional status, exercise habit and age were significantly associated with the combined unbalanced TCMC types.ConclusionThe majority of middle-aged Chinese women in Hong Kong had unbalanced and complex TCMCs. Qi-deficiency, Phlegm-wetness and Yang-deficiency constitutions are the most common constitutions. Poor systemic health condition, less-than-satisfactory emotional life, overweight and mental work are associated with and may be contributors for the formation of unbalanced TCMCs, while regular physical exercise was found to be a potential protective factor for unbalanced TCMCs.

Project description:BackgroundIn response to the World Health Organization's recommendation, policy makers have been adopting evidence-based healthcare approach to promote the development of traditional, complementary and integrative medicine (TCIM) into Hong Kong's health system. Disseminating synopses of clinical evidence from systematic reviews or randomized trials is regarded as a potentially effective strategy to promote evidence uptake. The study aimed to identify barriers and facilitators to implementing this strategy among Hong Kong Chinese medicine practitioners (CMPs).MethodsTwenty-five CMPs aged under 45 years and trained in Hong Kong after reunification with China in 1997 were interviewed individually. Four clinical evidence synopses of randomized trials and systematic reviews on Chinese medicine interventions were presented, and CMPs were asked to comment on their applicability in routine practice. The Consolidated Framework for Implementation Research (CFIR) was applied to guide interview and analysis.ResultsThe barriers included: i) CMPs' perceived difficulties in applying complex evidence in decision-making and ii) inadequate training and limited consultation time. The facilitators were i) availability of publicly accessible and user-friendly synopses, ii) formation of community of evidence-based practice among CMPs with input from key opinion leaders, iii) opportunity for interprofessional collaborations with conventional healthcare providers, and iv) patients' demand for evidence-based clinical advice. Besides, i) CMPs' knowledge and beliefs in evidence-based healthcare approach, ii) presentations of evidence-based information in the synopses, and iii) clinical decision making as influenced by quality of evidence reported acted as both barriers and facilitators.ConclusionsThis CFIR-based qualitative study investigated how the World Health Organization recommendation of promoting evidence use in routine practice was perceived by CMPs trained in Hong Kong after reunification with China in 1997. Key barriers and facilitators to applying evidence were identified. Such results will inform tailoring of implementation strategies for promoting evidence uptake, in the context of a well-developed health system dominated by conventional medicine.
