Lifestyle patterns and their nutritional, socio-demographic and psychological determinants in a community-based study: A mixed approach of latent class and factor analyses

Combined healthy lifestyle score and odds of rheumatoid arthritis in Iranian adults: a nested case-control from PERSIAN Dena Cohort Study (PDCS)

OBJECTIVES

Lifestyle factors play a significant role in the development of chronic diseases. While researchers have extensively studied individual lifestyle components, the combined impact of multiple lifestyle factors on rheumatoid arthritis (RA) remains unclear. This study aimed to explore the association between a Combined Healthy Lifestyle Score (CHLS) and the odds of developing RA among Iranian adults.

DESIGN

A nested case-control study.

SETTING

The study was conducted in Dena County (Sisakht region) near Yasuj city, Iran, as part of the PERSIAN Cohort Study.

PARTICIPANTS

130 RA cases and 260 matched controls, aged 35-70 years. Cases were identified based on biochemical tests and rheumatologist consultation.

OUTCOME MEASURES

Primary outcome was the odds of RA. Secondary outcomes included anthropometric measurements (body mass index (BMI), waist circumference) and dietary quality indicators.

METHODS

The CHLS score was calculated based on four parameters: smoking status, physical activity level, BMI and dietary quality, as assessed by the Healthy Eating Index-2020. Scores ranged from 0 (representing the unhealthiest lifestyle) to 4 (representing the healthiest lifestyle). Multiple logistic regression analysis was used to evaluate the association between CHLS and the odds of developing RA.

RESULTS

Participants with higher CHLS exhibited significantly lower BMI and waist circumference compared with those with lower scores. Additionally, higher CHLS was associated with greater consumption of fruits and whole grains (p<0.05). Individuals with the highest CHLS had 90% lower odds of developing RA compared with those with the lowest scores (OR 0.105; 95% CI 0.024 to 0.461, p trend=0.001), after adjusting for potential confounders.

CONCLUSIONS

Our findings suggest that adherence to a healthy lifestyle-characterised by non-smoking, regular physical activity, maintaining a normal BMI and following a healthy dietary pattern-is associated with reduced odds of developing RA among Iranian adults. The results of this study underscore the potential importance of combined lifestyle modifications in the prevention of RA. These insights emphasise the value of promoting comprehensive lifestyle changes as a strategy to mitigate RA risk.

Adherence to combined healthy lifestyle and odds of metabolic syndrome in Iranian adults: the PERSIAN Dena cohort study

The relationship between lifestyle choices and health outcomes has received significant scholarly attention. Research indicates that factors such as obesity, insufficient physical activity, tobacco use, and poor dietary habits may elevate the odds of developing metabolic disorders. This study aimed to investigate the association between the combined healthy lifestyle score (HLS) and the odds of metabolic syndrome (MetS) and its associated components in a population of apparently healthy adults. This cross-sectional study utilized data from the Dena PERSIAN cohort, which comprised 2,971 healthy adults. Participants' combined HLS were evaluated using validated questionnaires that assessed body mass index (BMI), physical activity level (PAL), smoking status, and dietary quality. The evaluation of dietary nutritional quality was conducted using the most recent version of the Healthy Eating Index (HEI), known as HEI-2020. The combined HLS was measured on a scale ranging from zero, indicating an unhealthy lifestyle, to four, representing the healthiest lifestyle. Individuals with the highest combined HLS score had 81% lower odds of having MetS compared to those with the lowest score (OR: 0.19; 95% CI: 0.11-0.33). Higher combined HLS scores were significantly associated with decreased odds of abdominal adiposity (OR: 0.11; 95% CI: 0.07-0.18), abnormal glucose homeostasis (OR: 0.55; 95% CI: 0.35-0.86), elevated serum triglycerides (OR: 0.41; 95% CI: 0.26-0.67), and low high-density lipoprotein cholesterol (HDL-C) levels (OR: 0.39; 95% CI: 0.24-0.65) after adjusting for sex, age, education level, and marital status (P < 0.05). The findings indicated a significant association between adherence to a combined HLS and a decreased odds of developing MetS and its associated components among Iranian adults.

Correlation Between Lifestyle Patterns and Cognitive Function Among Community-Dwelling Older Chinese Adults in the Pre-Dementia Stages: A Latent Class Analysis

Lifestyle activity engagement is a modifiable factor for cognitive decline. We aimed to identify lifestyle patterns (LPs) among community-dwelling older adults in the pre-dementia stages and to explore the links between LPs, cognitive function, and individual characteristics. 702 older Chinese adults were recruited. Three LPs were identified by latent class analysis: active aging lifestyle pattern (AALP), leisure lifestyle pattern (LLP), and work-centered lifestyle pattern (WLP). AALP refers to participation in various activities that are meaningful to individuals and benefit their well-being. LLP is the pattern of activities aimed at recreation. WLP refers to the LP where individuals are most likely to engage in work-related activities. However, only AALP is protected against mild cognitive impairment (MCI). Multinomial logistic regression models revealed the differences in individual characteristics among participants with different LPs, indicating the importance of tailored intervention strategies. As a protective factor against MCI, AALP should be highlighted in community-based care.

Opioid Use Disorder and intracerebral hemorrhage in Isfahan, Iran: a case-control study

Background

Opium use disorder is a significant health problem in our country, leading to a considerable number of health issues. Opium has several detrimental effects on its consumers. However, the effect of Opium use disorder on intracerebral hemorrhage (ICH) has not been evaluated. This study aims to evaluate the relationship between Opium use disorder and ICH.

Methods

In this case-control study, 402 patients with ICH and 404 patients without ICH enrolled. Opium use disorder, other vascular risk factors including diabetes mellitus, hypertension, hyperlipidemia, and tobacco smoking was compared between these groups. Patients with ICH were divided into two groups; first group are patients with history of Opioid Use Disorder and second group are those patients without Opioid Use Disorder. ICH features including clinical and imaging characteristics and prognostic findings were compared between patients with and without Opium use disorder.

Results

This case-control study of 806 participants found that hypertension (OR = 6.84, 95% CI: 5.03-9.34, p-value: <0.001), Opium use disorder (OR = 4.23, 95% CI: 2.42-7.35, p-value: <0.001) and tobacco smoking (OR = 1.47, 95% CI: 1.01-2.16, p-value: 0.049) had a higher risk of ICH. Opium-addicted subjects had higher ICH scores (2.61 ± 1.27 vs. 2.11 ± 1.29, p-value: 0.005), were more likely to have infratentorial hemorrhage (22% vs. 12%, OR = 2.13, 95% CI: 1.06-4.28, p-value: 0.038), more likely to be intubated (66% vs. 54%, OR = 1.79, 95% CI: 0.98-3.27, p-value = 0.041) and had lower GCS scores (9.58 ± 3.60 vs. 8.25 ± 3.88, p-value: 0.01). The effect of Opium use disorder independently on ICH was also shown in logistic regression (adjusted OR = 3.15, p-value = 0.001).

Conclusion

This study is the first to evaluate the effect of Opium use disorder on ICH, identifying Opium use disorder as a new potential risk factor for ICH.

Association between serum folate concentrations and all-cause mortality in U.S. adults: a cohort study based on National Health and Nutrition Examination Survey III

The association between serum folate and all-cause mortality in general population remains unclear. The objective of this study was to investigate the potential association between serum folate concentrations and all-cause mortality in a large, prospective, long-term U.S. cohort. Our study included adults from the National Health and Nutrition Examination Survey (NHANES) III, and mortality data was obtained by linking with the National Death Index (NDI) until December 31, 2019. Cox proportional hazard models were used to calculate hazard ratios (HR) and 95% confidence intervals (CI) to assess the association between serum folate concentrations and all-cause mortality. A total of 12,862 participants were included in this cohort study. After a median follow-up of 26.4 years [interquartile range (IQR), 15.4-28.7 years], a total of 5,299 deaths were recorded. The risk of death was lower by 12% per 1.0 g/L increase in log-transformed serum folate concentrations (HR, 0.88; 95% CI, 0.83-0.94). Compared with the lowest quartiles of serum folate level, the risk of death was lower in the second (HR, 0.84; 95% CI, 0.72-0.97), third (HR, 0.78; 95% CI, 0.68-0.91) and the highest quartiles (HR, 0.78; 95% CI, 0.69-0.88) in multivariable-adjusted model. In subgroup analyses, the inverse association between serum folate and all-cause mortality remained statistically significant for women, men and non-Hispanic White people. Higher serum folate levels were found to be significantly associated with reduced risk of all-cause mortality. However, further studies are needed to verify these findings and explore the underlying mechanism.

Optimizing lifestyle profiles is potential for preventing nonalcoholic fatty liver disease and enhancing its survival

The aim of this study was to evaluate the association between lifestyle profile and disease incidence/mortality in patients with non-alcoholic fatty liver disease (NAFLD). Lifestyle profiles ascertainment was based on the latent profile analysis. The associations of lifestyle profile and outcomes were analyzed by multivariate logistic or Cox regressions. Four lifestyle profiles (profile 1 and 2 for male, profile 3 and 4 for female) were established for all participants. Compared to profile 1, profile 2 (P = 0.042) and profile 3 (P = 0.013) had lower incidence for NAFLD. In contrast, profile 4 showed similar NAFLD prevalence compared to profile 1 (P = 0.756). Individuals with NAFLD within profile 3 had the best long-term survival, and the HR was 0.55 (95% CI 0.40-0.76) for all-cause mortality (compared to profile 1). Profile 4 (P = 0.098) and profile 2 (P = 0.546) had similar all-cause survival compared to profile 1. We explored the associations of healthy lifestyle score with mortality and incidence of NAFLD stratified by lifestyle profiles. We observed that with the increase of healthy lifestyle score, participants within profile 2 did not display lower NAFLD incidence and better long-term survival in NAFLD cases. In this study, lifestyle profiles were constructed in NHANES participants. The distinct lifestyle profiles may help optimize decision-making regarding lifestyle management in preventing NAFLD development, as well as selection of a more personalized approach for improving NAFLD survival.

Associations of Lifestyle Patterns with Glucose and Lipid Metabolism in Finnish Adults at Increased Risk of Type 2 Diabetes

SCOPE

Various lifestyle and sociodemographic factors have been associated with risk factors for type 2 diabetes (T2D). However, their combined associations with T2D risk factors have been studied much less.

MATERIALS AND RESULTS

This study investigates cross-sectional associations of lifestyle patterns with T2D risk factors among 2925 adults at increased risk participating in the Stop Diabetes study. Lifestyle patterns are determined using principal component analysis (PCA) with several lifestyle and sociodemographic factors. The associations of lifestyle patterns with measures of glucose and lipid metabolism and serum metabolites analyzed by nuclear magnetic resonance (NMR) spectroscopy are studied using linear regression analysis. "Healthy eating" pattern is associated with better glucose and insulin metabolism, more favorable lipoprotein and fatty acid profiles and lower serum concentrations of metabolites related to inflammation, insulin resistance, and T2D. "High socioeconomic status and low physical activity" pattern is associated with increased serum concentrations of branched-chain amino acids, as are "Meat and poultry" and "Sleeping hours" patterns. "Snacks" pattern is associated with lower serum concentrations of ketone bodies.

CONCLUSIONS

Our results show, in large scale primary care setting, that healthy eating is associated with better glucose and lipid metabolism and reveal novel associations of lifestyle patterns with metabolites related to glucose metabolism.

The Association of HDL2b with Metabolic Syndrome Among Normal HDL-C Populations in Southern China

Background

The annual prevalence of metabolic syndrome (MetS) is increasing. Therefore, early screening and recognition of MetS are critical. This study aimed to evaluate the association between high-density lipoprotein (HDL) subclasses and MetS and to examine whether they could serve as early indicators in a Chinese community-based population with normal high-density lipoprotein cholesterol (HDL-C) levels.

Methods

We used microfluidic chip technology to measure HDL subclasses in 463 people with normal HDL levels in 2018. We assessed how HDL subclasses correlated with and predicted insulin resistance (IR) and metabolic syndrome (MetS), evaluated by homeostatic model insulin resistance index (HOMA-IR) and the 2009 International Diabetes Federation (IDF), the American Heart Association (AHA), and the National Heart, Lung, and Blood Institute (NHLBI) criteria, respectively. We used correlation tests and ROC curves for the analysis.

Results

The results indicate that there was a negative association between HDL2b% and the risk of IR and MetS in both sexes. Subjects in the highest quartile of HDL2b% had a significantly lower prevalence of IR and MetS than those in the lowest quartile (P<0.01). Correlation analysis between HDL2b% and metabolic risk factors showed that HDL2b% had a stronger association with these factors than HDL-C did in both sexes. ROC curve analysis also showed that HDL2b% had significant diagnostic value for IR and MetS compared to other lipid indicators.

Conclusion

This study showed that MetS alters the distribution of HDL subclasses even when HDL-C levels are within the normal range. HDL-2b% has better diagnostic value for IR and MetS than HDL-C alone and may be a useful marker for early screening.

Lifestyle patterns, nutritional, and metabolic syndrome determinants in a sample of the older Iranian population

BACKGROUND

Chronic diseases and metabolic disorders are prevalent health concerns that often escalate with increasing age and thus affect older individuals. The proportion of the elderly population in Iran increased from 7.22% in 2006 to 12.0% in 2023. The current study aimed to evaluate lifestyle patterns and lifestyle risk factors among patients with metabolic syndrome (MetS) based on dietary, physical activity, and smoking, as well as MetS components.

METHODS

This cross-sectional study included 582 older people with MetS living in Yazd, Iran. Latent class analysis (LCA) was used to determine the lifestyle behaviors of diet patterns, smoking, and physical activity. Dietary intake was measured using a validated food frequency questionnaire, and dietary patterns were identified using principal component analysis (PCA). Clinical measurements of MetS components were examined using relevant guidelines.

RESULTS

The mean age of the participants was 72.71 years (SD = 5.57). Using PCA, two dietary patterns were identified: traditional patterns (e.g., fruits, fish, poultry, vegetables, meats, salt, and sugar sweetened beverages) and high-fat patterns (e.g., high-fat dairy). Applying LCA identified two classes of lifestyle patterns. About 35% (n = 204) of the participants were categorized in a low-risk class (I) and characterized by physical activity (0.93%, n = 190), a traditional pattern for diet (61%, n = 122), and zero probability of smoking. About 65% (n = 378) of the patients were categorized in high-risk class (II) and characterized by low physical activity levels (69%, n = 261), cigarette smoking (71.6%, n = 271), and a high-fat dietary pattern (56.9%, n = 215).

CONCLUSION

The results of our study indicated two distinct classes within the patients. In class I, aging patients with MetS exhibited characteristics such as engagement in physical activity and having a traditional pattern for diet. Class II, with a higher prevalence of lifestyle risk factors, included individuals who engaged in cigarette smoking, displayed low physical activity (69%), and having a high-fat diet. The combination of these lifestyle factors exposed them to a heightened risk of developing MetS. The findings could guide healthcare professionals to be aware of the associations between different lifestyle risk factors and to focus on multiple behaviors at the same time.

Diet and Lifestyle in the Spanish Population and Their Relationship with Sociodemographic Variables: A Descriptive Study

A healthy lifestyle and proper nutrition have a major impact on the well-being of a population. Therefore, the aim of this research is to describe the behavior of these habits in relation to sociodemographic variables to provide data on the development of effective training and awareness-raising actions.

METHODS

An observational, descriptive and cross-sectional study was carried out. To study the behavior of a series of variables related to eating habits and lifestyle, a questionnaire was designed and validated and subsequently disseminated online, by means of nonprobabilistic snowball sampling, relying on social networks. The sample collected consisted of 18,070 young adults of Spanish nationality. Bivariate comparative analyses were performed using t-test independent samples, and the effect size (ES) was calculated by determining Cohen's D coefficient. A multivariate analysis were conducted using linear regression and principal component analysis.

RESULTS

Adults eat better but have a poorer quality of rest and are more sedentary than young people. No gender differences were found in nutritional habits; however, men engage in more sports and sleep better. People with a higher educational level have better nutritional and sleep habits, but are more sedentary, as are people of a higher socioeconomic level.

CONCLUSIONS

Higher socioeconomic and educational levels seem to favor a healthier lifestyle. The Spanish population aged 18-45 years needs to make dietary changes but leads an active lifestyle.

Clustering of metabolic and behavioural risk factors for cardiovascular diseases among the adult population in South and Southeast Asia: findings from WHO STEPS data

Background

The aim of this study is to assess the current status of metabolic and behavioural risk factors for cardiovascular diseases among the adult population in South and Southeast Asia using World Health Organization (WHO) STEPS data.

Methods

We used WHO STEPS surveys data in ten South and Southeast Asian countries. Weighted mean estimates of prevalence of five metabolic risk factors and four behavioural risk factors were calculated by country and overall region. We used random-effects meta-analysis to generate country and regional pooled estimates of metabolic and behavioural risk factors, using the DerSimonian and Laird inverse-variance method.

Finding

Around 48,434 participants aged 18-69 years were included in this study. Overall 32.00% (95% CI: 31.15-32.36) of individuals in the pooled sample had one metabolic risk factor, 22.10% (95% CI: 21.73-22.47) had two, and 12.38% had three or more (95% CI: 9.09-14.00). Twenty-four percent (95% CI: 20.00-29.00) of individuals in the pooled sample had only one behavioural risk factor, 49.00% (95% CI: 42.00-56.00) had two, and 22.00% had three or more (95% CI: 16.00-29.00). Risk of high three or more metabolic risk factors was higher among women, those of older age, and those with a higher education.

Interpretation

The existence of multiple metabolic and behavioural risk factors among the South and Southeast Asian population demand appropriate prevention strategies to halt the progress of non-communicable disease burden within the region.

The association between healthy lifestyle score and risk of metabolic syndrome in Iranian adults: a cross-sectional study

BACKGROUND

Lifestyle risk factors, such as obesity, physical inactivity, smoking, and having an unhealthy diet are significantly associated to the risk of developing metabolic diseases such as type 2 diabetes, insulin resistance, and metabolic syndrome (MetS). Consequently, it is important to examine multiple lifestyle risk factors instead of single ones. Moreover, the combined effects of these factors on risk of MetS are not fully investigated. This study investigated the relationship between HLS and MetS and its components among apparently healthy adults living in Tabriz-Iran.

METHODS

This cross-sectional study includes 347 apparently healthy adults aged 20-50. To assess healthy lifestyle, four habits were used to examine HLS: physical activity (PA), smoking, healthy eating index-2015 (HEI-2015), and body mass index (BMI). Smoking status, PA, and dietary intakes (147-item) of study participants were evaluated using valid questionnaires. The lifestyle score ranged from zero (non-healthy) to four (most healthy) points. Binary logistic regression with adjusted models was used to examine the association of HLS and MetS, and its components. P < 0.05 was considered statistically significant.

RESULTS

In the current study, the average age and BMI of study participants were 40.78 ± 9.23 years old and 29.23 ± 5.97 kg/m², respectively. Participants in the highest quartile of HLS had significantly lower waist circumference (WC), BMI, weight, and had less fasting blood sugar (FBS), and triglyceride (TG) compared to the lowest quartile of HLS. Individuals in the second quartile of HLS had 24% greater odds for having MetS compared with those in the first quartile (adjusted OR: 1.24; 95% CI: 1.05-2.66). A significant reduction in hyperglycemia (adjusted OR: 0.85, 95% CI: 0.55-0.96) and high TG (adjusted OR: 0.83; 95% CI: 0.55-0.93) risk was also observed in the highest category of HLS compared to the lowest category. Moreover, after taking potential confounders into account, low score of HLS was associated with increased odds of MetS in women (adjusted OR: 1.32; 95% CI: 1.03-2.91).

CONCLUSION

The results showed that the lowest adherence to HLS was associated with higher odds MetS in women, after adjusting for all covariates. Moreover, adherence to a healthy lifestyle was related to lower odds of hyperglycemia and high TG in Iranian adults. To confirm these results, prospective studies are required.

Multiple health risk behaviors, including high consumption of ultra-processed foods and their implications for mental health during the COVID-19 pandemic

Background and aim

The growing increase in diet- and behavior-related illnesses has drawn the attention of many epidemiologists who attribute such changes to the epidemiological and nutritional transition. Thus, this study aims to evaluate the association between the combined occurrence of health risk behaviors, such as sedentary lifestyles, high weekly consumption of ultra-processed foods (UPFs), and non-daily consumption of fruits and vegetables, and symptoms of anxiety or depression in adults.

Methods

This is a cross-sectional study based on an epidemiological survey in two Brazilian cities. The outcome, anxiety, and depression symptoms were assessed using the Generalized Anxiety Disorder 7-item (GAD-7) and the Patient Health Questionnaire-9 (PHQ-9). Food consumption was assessed using a qualitative food frequency questionnaire (FFQ) with reference to consumption in the last 3 months and categorized into the consumption of fruits and vegetables and the consumption of UPFs according to the NOVA classification. Sedentary behavior was assessed by considering the amount of sitting or reclining time per day reported by participants and categorized as less than 9 h of sitting or reclining and 9 h or more. For the analysis, adjusted Poisson regression (PR) was used to estimate the prevalence ratio and the 95% confidence interval (CI).

Results

Those with the health risk behaviors, non-daily consumption of fruits and vegetables, and high consumption of UPFs had a 2.6 higher prevalence ratio for symptoms of mental disorder (PR: 2.6 and 95%CI: 1.1–6.5), as well as those with all three health risk behaviors, had a 2.8 higher prevalence ratio for symptoms of mental disorder (PR: 2.8 and 95%CI: 1.3–6.1).

Conclusion

This study revealed that the existence of a combination of two and three health risk behaviors led to a higher prevalence of symptoms of anxiety or depression.

A cross sectional survey of 504 women regarding perceived risk factors and barriers to follow healthy lifestyle and association with sociodemographic factors and menopausal symptoms

BACKGROUND AND AIMS

Midlife women undergoing menopausal transition are predisposed to weight gain. Weight gain in midlife is driven by two modifiable risk factors: menopausal symptom's severity and lifestyle practices. The independent and interactive nature of menopausal symptoms and lifestyle practices as risk factors of weight gain has not been investigated yet. This study was undertaken to study menopausal symptoms and lifestyle practices as risk factors for weight gain in midlife women and identify midlife -related barriers in managing corrective lifestyle practices.

METHODS

In this cross-sectional study, menopausal symptom severity and lifestyle practices such as diet, exercise, and sleep were assessed using a pre-validated and reliable questionnaire on a convenience sample of midlife women (43-55 years) via an interview schedule. The association of lifestyle practices and its barriers with socio-demographics and menopausal symptoms were analysed.

RESULT

A total of 504 women (mean age: 47.3 ± 4.1 years) were recruited. More than half of them followed corrective dietary practices, but only one-fourth engaged in moderate-intensity exercises. Total menopausal symptom severity was associated with increased food intake (P < 0.001), joint pain with limited physical activity and hot flashes and emotional volatility with sleep disturbances (P < 0.01). Demographic variables such as education, economic and employment status were associated with unhealthy lifestyle practices.

CONCLUSION

Assessment of menopausal symptoms and lifestyle practices as risk factors and associated barriers must be the pivotal component to devise comprehensive women-centric weight management modules. Similar studies should be carried out in future when there is no clear effect of COVID19 on lifestyle factors.

Dietary Patterns and Their Association with Sociodemographic and Lifestyle Factors in Filipino Adults

Recent studies have investigated dietary patterns to assess the overall dietary habits of specific populations. However, limited epidemiological research has been conducted to explore the unique dietary intakes in low and middle-income countries. This study aims to examine the dietary patterns of Filipino adults and their association with sociodemographic and lifestyle factors. A total of 10,025 adults (≥20 years old) who participated in the 2013 Philippine National Nutrition Survey were included in the analysis. Dietary patterns were derived using factor analysis of 18 food groups from the dietary survey component. Six dietary patterns were identified, namely (1) rice; (2) cereal, milk, sugar, and oil; (3) fruits and miscellaneous food; (4) fish; (5) vegetables and corn; and (6) meat and beverage. Generalized ordered logistic regression analysis indicated that the dietary patterns were associated with different factors, specifically sex, age, educational attainment, marital status, employment status, household size, wealth quintile, smoking status, alcohol consumption, and physical activity. Our findings showed distinct dietary patterns among Filipino adults that were influenced by various sociodemographic and lifestyle parameters. The results of this study have valuable public health implications and the dietary patterns generated can further be used to analyze the link between diet and health outcomes.

Applying Latent Profile Analysis to Identify Lifestyle Profiles and Their Association with Loneliness and Quality of Life among Community-Dwelling Middle- and Older-Aged Adults in South Korea

This study aimed to examine the multi-faceted lifestyle profiles of community-dwelling middle- and older-aged adults based on their physical activity, participation in various activities, and nutrition. It identified the association of lifestyle profiles with demographic variables, quality of life, and mental health. The analysis included 569 participants (mean age = 60.2; SD = 4.3). Latent profile analysis identified three distinctive lifestyle profiles: "inactive and unbalanced" (36.4%), "basic life maintenance" (54.6%), and "active and balanced" (9.1%). Sex (p < 0.001), age (p < 0.001), and regular medication intake (p < 0.01) were statistically significantly different among the three profiles. Of the "inactive and unbalanced" lifestyle group, 63.3% of it was comprised of by females, and a relatively large distribution was aged over 65. In the "basic life maintenance" subgroup, males showed a relatively large distribution, and 92.6% of participants were aged 55-64. People with active and balanced lifestyles demonstrated high quality of life levels (p < 0.001) and low loneliness levels (p < 0.01). Multinomial logistic regression revealed a statistically significant positive association between lifestyle profiles and quality of life (p < 0.001) as well as mental health (p < 0.01). Therefore, health promotion that considers multi-faceted lifestyle factors would need to improve health and quality of life among community-dwelling middle- and older-aged adults in South Korea.

Spatial-Temporal Footprints Assessment and Driving Mechanism of China Household Diet Based on CHNS

Food consumption is closely associated with resource consumption and environmental sustainability. An unreasonable dietary pattern would cause great pressure or damage to resources and the environment. It is particularly important to reduce the negative impact of household food consumption on resources and the environment while simultaneously ensuring people’s nutrient intake and health. This study applied the China Health and Nutrition Survey (CHNS) database to quantitatively study the spatial-temporal analysis of multiple footprints of household food consumption at multiple scales and explored the driving mechanism of the multiple footprints. The results showed that, except land footprint (LF), the other four types of footprints all decreased at varying degrees; the water footprint (WF), carbon footprint (CF), nitrogen footprint (NF) and energy footprint (EF) decreased by 18.24%, 17.82%, 12.03% and 20.36%, respectively, from 2000 to 2011; multiple footprints of food consumption of household in Guizhou was the highest among the 12 provinces involved in the study; this shows that resource consumption (water, energy and land resource) and environmental influences (CO₂ emissions and nitrogen emissions) brought by food consumption of per household in Guizhou are much greater than in other provinces, which has a negative influence on sustainable development; by analyzing the driving factors of multiple footprints, it is shown that nutrient intake, household attributes, educational level and health conditions were significantly correlated to multiple footprints. Among them, nutrient intake has greater impact on the multiple footprints of Chinese household food consumption. By comparing multiple footprints of different dietary patterns, it was found that the current Chinese dietary pattern would cause excessive resource consumption, which would bring more pressure on resources and the environment. Adjusting household living habits would possibly reverse the unsustainable situation, such as reducing the consumption of animal-derived foods and adjusting the dietary pattern of households with a higher educational level and income status. Chinese Dietary Guidelines 2016 has better sustainability; the promotion of this dietary pattern across the country would help China to relieve the pressure on resources and environment from the consumer side, promoting the realization of sustainable development.
