A community-based cross-sectional study of dietary composition and associated factors among tuberculosis patients in China.

ABSTRACT: To determine the dietary structure and its associated factors of tuberculosis (TB) patients in the community. This cross-sectional study analysed the dietary intake of 300 TB patients in two impoverished counties in China. Food intake was collected by using food frequency and two consecutive 24-h dietary review (24hdr) methods. The dietary composition and dietary structure of TB patients were compared with China's 2022 Dietary Reference Intake (DRIs) and the average reference value of dietary composition (ARC) in China in 2013. Binary logistic regression models were used to explore the factors associated with inadequate intake of animal food, insufficient protein and fat energy supply in patients with TB. The daily intake of various foods in TB patients was measured and the results were as follows: staple foods-median 372.12 g (interquartile range [IQR] 315.87 g); vegetables-median 200.00 g (IQR 205.55 g); fruits-median 20.22 g (IQR 36.82 g); animal foods-median 100.82 g (IQR 180.74 g); dairy products-median 0.00 g (IQR 0.00 g); nuts-median 17.10 g (IQR 29.75 g). The average daily intakes of vegetables, fruits, animal food, dairy products, soy and nuts were lower than those recommended by the DRIs (P < 0.01). Compared to women, men consumed more whole grains and mixed legumes, but less fruit. The dietary structures, including food and nutrient supply for energy, protein and fat, were significantly different in 300 patients compared with DRIs or ARC values. Inadequate rates of animal food intake were observed in 54.85% of men and 59.57% of women. Protein undersupply rates were 66.02% in men and 56.38% in women, while fat undersupply rates were 52.91% in men and 52.13% in women. The study revealed that being 18-49 years old, being the Han nationality, having less than 2 h of physical activity per day on average, and eating twice a day were risk factors for inadequate animal protein intake, protein energy deficiency and fat energy deficiency. TB patients from impoverished counties in China have inadequate intake of several food categories and insufficient protein and fat energy supply, correlating with multiple factors in socio-demographics, behavioral practices, and TB disease. To improve the nutritional status of TB patients, urgent public health actions, especially carrying out nutritional screening and evaluation once diagnosed, developing individualized nutritional support treatment plans, strengthening dietary nutritional health education and intervention, and advocating for enhanced nutritional support, should be taken.

Project description:BACKGROUND:Community-based diabetes management is known to be an important strategy for global diabetes control. In China, community-based diabetes management care, including regular blood glucose tests and guidance on medicine use, dietary control, and physical exercise provided by primary health institutions (PHIs), as one of the key contents of the national essential public health services (EPHS), was implemented since 2009 when the new round of health system reform was initiated. This study aimed to investigate the utilization of community-based diabetes management care services, and explore the factors influencing utilization from both patients' and providers' points of view. METHODS:In total, 2520 type-2 diabetes mellitus (DM) patients registered for EPHS were selected from 63 PHIs in eight counties of Shandong province, China, using multi-stage stratified sampling. Of those, 2166 patients (response rate: 85.4%) completed face-to-face structured questionnaires on their utilization of community-based diabetes management care services. Further, 63 PHIs were surveyed on diabetes care delivery, and 444 primary healthcare providers were purposively sampled from those PHIs to measure their knowledge of diabetes management care delivery, using a self-developed questionnaire. Descriptive statistics were used to analyze the delivery and utilization of diabetes management care services. Multilevel logistic regression models were used to analyze the factors associated with patients' utilization of diabetes management services. RESULTS:All 63 PHIs reported that all the required four diabetes management services were provided through EPHS. However, only 49.6% of the patients reported they fully used these services, with no statistically significant difference between urban and rural patients. Patients who had higher knowledge of diabetes and better self-efficacy in controlling the condition, were more likely to fully utilize diabetes management care. A larger number of PHI health staff per 1000 population was associated with better utilization of care. CONCLUSION:Although community-based diabetes management services are well available to Chinese DM patients under the framework of EPHS, the actual utilization of diabetes management services among the patients was poor. The size of the PHI workforce, patients' knowledge and self-efficacy in controlling diabetes, were important predictors of utilization, and could be enhanced to improve control of diabetes.

Project description:Although considerable progress has been made on the risk factors of dementia, less is known about the extent of the gaps between the general public's understanding of dementia prevention and contemporary scientific evidence. This study aimed to determine the beliefs and knowledge of dementia prevention among the Chinese general public and examine the socio-demographic factors of the belief and knowledge of dementia prevention. The study adopted a cross-sectional design. A total of 358 Chinese adults aged over 40 years were recruited from four healthcare centers. We designed questionnaires that include items on the belief of dementia prevention, risk factors for dementia, and health education needs regarding dementia prevention based on previous literature. Descriptive statistics and multivariate regression analyses were conducted. Only 32.4% of the respondents agreed that dementia is preventable. Less participants were able to correctly identify cardiovascular risk factors (i.e., obesity, diabetes, dyslipidemia, hypertension, unhealthy diet, smoking, and alcohol) as part of dementia risk factors. Younger age, higher education, and having contact with patients with dementia are associated with stronger belief that dementia is preventable. Older age, higher income, higher education, having memory complaint, and having contact with patients with dementia are associated with a better understanding of dementia risk factors. A total of 88.9% respondents thought that they are not well informed of dementia from public education, and most respondents (65%) prefer receiving dementia-related health advice from primary care providers. The present study reveals the great gaps between the Chinese general public's knowledge of dementia prevention and the latest research evidence. Public health educational programs for all age groups are encouraged to close this knowledge gap. More attention and resources should be paid to individuals with low income and low education level as they have limited access to dementia prevention information. Researchers should work in partnership with primary care providers to help translate evidence into community practice with a special focus on the link between cardiovascular risk factors and dementia.

Project description:ObjectivesPublic investment in community health centres (CHCs) has been increasing as a response to rapid urbanisation in China. The objectives of this study were: (1) to examine factors associated with CHC use among residents from a recently urbanised community in western China and (2) to describe satisfaction with CHC among users.DesignCross-sectional design.SettingA community recently converted to urban status with a newly constructed CHC in Southwest China.ParticipantsA random sample of 2259 adults in the Hezuo community in Chengdu, China, completed the survey in 2013.Outcome measuresTrained staff interviewed study participants in their homes using structured questionnaires. The survey included questions regarding sociodemographics, health status, access to and usage of healthcare, health behaviours and CHC use. The Andersen's behavioural model of health service use was used to guide multivariable logistic regression modelling in identifying predisposing, enabling and need factors associated with the likelihood of using CHC. Descriptive statistics were used to describe residents' satisfaction with the CHC.ResultsA total of 71.8% of the respondents reported using the CHC during the past year. Factors influencing adults' CHC use included: gender, marital status, education level and knowledge of one's blood pressure (predisposing factors); annual household per capita income and walking time to the CHC (enabling factors) and self-rated health as well as physical activities (need factors). CHC users reported modest satisfaction across various aspects of the CHC.ConclusionsNeighbourhood CHC in urban areas provides important services to these residents living in a recently urbanised community. All three categories of factors in the Andersen model help explain the likelihood of CHC use. There is much room for improvement in CHC to enhance customer satisfaction. Future research is needed to improve access to CHCs and promote their use in urbanised populations with low to modest education.
