Health Knowledge about Smoking, Role of Doctors, and Self-Perceived Health: A Cross-Sectional Study on Smokers' Intentions to Quit

Patients' perception of lifestyle advice as a mechanism between health shocks and health behaviours: Evidence from a longitudinal study in China

Background

The heavy burden of non-communicable chronic diseases (NCDs) and the deficiency of health behaviours (HB) are threatening the middle- and older-aged population in China. However, little is known about the relational mechanism between health shocks (HS) and HBs, while the importance of patients' perception of lifestyle advice (PPLA) to initiate HB is insufficiently emphasised. In this study, we aimed to examine this perception as a mediator between HS and HB and the variety of mediation effects caused by the different contents of lifestyle advice.

Methods

We retrieved panel data from the two latest waves of a nationally representative cohort, the China Health and Retirement Longitudinal Study (CHARLS). After constructing well-balanced groups through propensity score matching, we conducted descriptive and multilevel logistic regression analyses to analyse the state of and factors influencing PPLA. We employed the Preacher's Sobel test with 1000 replications bootstrap to examine the mediating effect of PPLA.

Results

On a sample of 7922 respondents (post-propensity score matching), we found that HSs had a positive direct effect on HB, with observed decreases in smoking and drinking and increases in exercise. A limited and selected perception of lifestyle advice showed a gap between the advice given by providers and perceived by patients, with gender, education level, social support inside the family, self-reported health, comorbidity, treatment regimens, and utilisation of family doctors being significant influencing factors. Nevertheless, any content of lifestyle advice partially mediated the relationship in which HS increases non-addictive HB (exercise), while only the targeted and detailed content of lifestyle advice about corresponding behaviours partially mediated the effect between HS and addictive HB (smoking and drinking).

Conclusions

This study provides the first evidence that PPLA partially mediates the positive effect of HS on HB. Personalised chronic disease management; targeted advice and interventions; and multiple social resources COULD BE beneficial for patients with HS to initiate HB.

Healthcare providers' knowledge, attitudes and practices on smoking cessation intervention in the Northern Cape

Background

Clinicians are crucial in encouraging smokers to quit through behavioural or pharmacological smoking cessation interventions. Smokers quit better with professional help. The level of healthcare providers' (HCPs) knowledge, attitudes and counselling skills related to effective smoking cessation support in the study area remains uncertain.

Aim

The study aimed to determine HCPs' knowledge, attitudes and practices (KAP) on smoking cessation intervention strategies in the Sol Plaatje district, Northern Cape.

Setting

Sol Plaatje's 13 district municipality clinics, Kimberley, Northern Cape.

Method

A descriptive, cross-sectional analytical study involving healthcare workers in the above setting.

Results

A total of 165 HCPs, including medical officers, professional nurses, enrolled nurses and assistant-enrolled nurses working in primary healthcare clinics, were invited to participate in the study, with 156 completing the questionnaires. About 53.9% had no knowledge of South African tobacco smoking cessation guidelines, while 87.2% knew the importance of counselling patients about smoking and its impact on quitting. The majority of them did not know the medicines recommended for tobacco treatment in South Africa. About 89.7% expressed that smoking cessation counselling is an important part of their jobs. However, less than half indicated that they make follow-up arrangements for those attempting to quit.

Conclusion

The study revealed gaps in KAP regarding smoking cessation among the respondents, necessitating the need for continuing education on the existing smoking cessation guidelines among these HCPs.

Contribution

The results of this study will help to improve smoking cessation intervention knowledge among health providers.

The influence of health literacy and knowledge about smoking hazards on the intention to quit smoking and its intensity: an empirical study based on the data of China's health literacy investigation

OBJECTIVE

This study explored the relationship between smokers' health literacy, knowledge of smoking hazards, and their intention to quit.

METHODS

Based on data from the 2019 Health Literacy and Tobacco Use Surveillance among residents of a city in Zhejiang Province, 1120 male smokers were screened. Differential tests were used to analyze whether smokers with varying levels of health literacy and knowledge about smoking hazards differed in their intention to quit smoking and the intensity of their intention. A multi-factor logistic regression model was constructed to explore the extent of these differences.

RESULTS

Only 24.8% of smokers had higher health literacy. Among smokers, those with an intention to quit had a higher health literacy level compared to those without such intention (32.7% vs. 17.0%, p < 0.001). Health literacy levels did not differ significantly between groups with different intensity of intention to quit (34.2% vs. 31.9% vs. 30.1%, p = 0.435). About 48.7% of the smokers a higher level of knowledge about smoking hazards. It was more prevalent in the intent to quit group compared to the no intent to quit group (54.0% vs. 43.4%, p < 0.001), and the low intent to quit group had lower knowledge compared to the moderate and high intent to quit groups (49.1% vs. 56.6% vs. 63.4%, p = 0.011). After adjusting for other influences, smokers with lower health literacy were less likely to have intention to quit (OR = 0.659, p = 0.016). And the association between knowledge about smoking hazards and whether smokers have the intention to quit is no longer significant, but it significantly affects the intensity of the intention to quit among smokers who already have the intention (OR = 0.623, p = 0.005).

CONCLUSION

General health literacy may play a role in facilitating smokers' progression from the stage of no intent to quit to one of intent to quit, but a more specific understanding of the harms of smoking may be needed to increase the strength of intent to quit.

Influence of health literacy on health outcomes of different social strata-- an empirical study based on the data of China's health literacy investigation

BACKGROUND

Health literacy has always been considered as an important factor to promote people's health, but does it have a significant effect on health across all social strata and especially lower social strata? This study aims to analyze the influences of health literacy on health outcomes of different social strata, and then infer whether improving health literacy can reduce health disparities among different social strata.

METHODS

Utilizing health literacy monitoring data from a city in Zhejiang Province in 2020, the samples are divided into three social strata according to the socioeconomic status score: low, middle and high social stratum, to compare whether there are significant differences in health outcomes between population with lower and higher health literacy among different social strata. In the strata with significant differences, control the confounding factors to further verify the influence of health literacy on health outcomes.

RESULTS

In low and middle social strata, there are significant differences between population with lower and higher health literacy, when considering the two types of health outcomes (chronic diseases and self-rated health), but in high social stratum, this difference is not significant. After controlling the relevant variables, the influence of health literacy on the prevalence of chronic diseases is statistically significant only in low social stratum, and the health literacy is negatively correlated with the prevalence of chronic diseases(OR = 0.722, P = 0.022). In addition, there are statistical significances for positive impact of health literacy on self-rated health in both low and middle social strata (OR = 1.285, P = 0.047; OR = 1.401, P = 0.023).

CONCLUSION

Compared with high social stratum, the influence of health literacy on health outcomes of low social stratum (chronic diseases) or both middle and low social strata (self-rated health) is more significant, and both are to improve the health outcomes. This finding suggests that improving residents' health literacy may be an effective way to alleviate the health disparities among different social strata.

Association between ethnicity and health knowledge among the floating population in China

Background

Health equity remains a priority concerns by central government in China. This study aimed to explore ethnic gaps in access to health knowledge categories and sources based on the survey data from a publicly available dataset.

Methods

Data were from 2015 China Migrants Dynamic Survey issued by The National Health Commission in China. Descriptive analyses were performed to reflect geodemographic differences in the floating population of ethnic minority (EMFP) and Han majority (HMFP) with Chi-square test. Ethnic gaps in access to health knowledge categories and sources were explored with Poisson regressions, logistic regressions, and bivariate ordered probit regressions.

Results

In the sample, most of participants had inadequate health information literacy. There were significant differences regarding geodemographic factors between EMFP and HMFP. Illiterate EMFP had likelihood to obtain less health knowledge categories (IRR = 0.80, 95% CI 0.77–0.84) and sources (IRR = 0.83, 95% CI 0.80–0.86) as compared to illiterate HMFP. Most of correlations between health knowledge categories and sources were weak in the samples of EMFP and HMFP.

Conclusion

Ethnic disparities in access to health knowledge categories and sources among the floating population in China were confirmed. Further effective efforts should be provided to reduce ethnic disparities in access to health knowledge under the ethnicity-orientated support of public health resource.

The Community Health Supporting Environments and Residents' Health and Well-Being: The Role of Health Literacy

We evaluate the impacts that health supporting environments have on residents' health and well-being. Using a stratified multi-stage sampling method, we select a sample of 12,360 permanent adult residents aged 15-69, and collect information on their health literacy level, as well as their demographic background and health. This individual level data is then merged with the administrative health supporting environment data. More than two thirds of residents self-reported having good/excellent health, and the percent of adults living in communities with healthy parks, healthy trails, and healthy huts in their community is 23 percent, 43 percent, and 25 percent, respectively. Controlling for a series of confounding factors at the community and individual levels, we find that healthy parks and healthy trails are positively correlated with self-reported health, which increases the probability of self-reporting good health by 2.0 percentage points (p < 0.10) and 6.0 percentage points (p < 0.01), respectively. Access to healthy huts is negatively associated with self-reported health, decreasing the probability of self-reporting good health by 5.0 percentage points (p < 0.01). Health literacy plays a role in moderating the effect of health parks, and a positive effect is more likely to be observed among adults with lower health literacy. Health supporting environments may play a role in reducing the likelihood of undiagnosed diseases and changing residents' lifestyles, which promotes the health and well-being of residents, especially among those with inadequate health literacy.
