Lin J, Yang F, Lan M, Ding Y, Yin K. Adhere to the Chinese dietary guidelines associated with better subjective well-being: evidence from a cross-sectional survey and a daily diary investigation. BMC Public Health 2024; 24:445. [PMID: 38347466 PMCID: PMC10863138 DOI: 10.1186/s12889-024-17880-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2023] [Accepted: 01/24/2024] [Indexed: 02/15/2024] Open
Abstract
BACKGROUND Subjective well-being (SWB) plays an essential role in general health. Although beneficial effects of selected micronutrients and foods on SWB have been reported, they do not reflect the impact of the habitual diet on SWB. Therefore, the purpose of this study is to investigate the association between adherence to the Chinese Dietary Guidelines (CDG) with SWB. METHODS This study combined a cross-sectional survey and a daily diary investigation. The cross-sectional survey was conducted on 1,433 students from 8 universities in southern China between October and November 2020. The daily diary investigation was conducted in November 2022, collecting 10-day daily data from 115 students at two universities in southern China over ten consecutive days, resulting in 1,020 valid matched daily responses. Adherence to the CDG was assessed by the China Prime Diet Quality Score (CPDQS), SWB was measured by the Index of Well-being (IWB) and the Affect Valuation Index (AVI). Correlation analysis, multiple regression analyses, and hierarchical regression were conducted to examine the associations of adherence to the CDG with its components, and SWB. RESULTS The cross-sectional survey revealed significant predictors of SWB, including adherence to the CDG (β = 0.24, p<0.001) and its components: cereals and tubers (β = 0.07, p = 0.024), vegetables and fruits (β = 0.11, p<0.001), dairy/soy/nuts (β = 0.11, p = 0.002), and condiments and alcoholic beverages (β = 0.08, p = 0.002). The daily diary investigation showed positive associations between adherence to the CDG (β = 0.19, p<0.001), and its components: vegetables and fruits (β = 0.11, p = 0.001), dairy/soy/nuts (β = 0.06, p = 0.009), animal source food (β = 0.06, p = 0.026), and condiments and alcoholic beverages (β = 0.07, p = 0.026), with higher levels of daily SWB. CONCLUSIONS Adherence to healthy dietary patterns such as the CDG, rather than focusing on individual components in isolation, is associated with better SWB. Furthermore, the consumption of CDG components had an impact on SWB, although the specific effects varied between the two studies. This study offers modest evidence supporting the role of the CDG in promoting positive mental health.

Abstract
BACKGROUND Happiness is an important factor for everyone's good health and general well-being. Medical students need to manage a lengthy medical curriculum, clinical postings, and the stressful environment of hospital setting, which may have considerable effects on their happiness. No such studies have been conducted in the remotely located Andaman and Nicobar (A and N) islands. Hence, the current study was conducted to determine the level of happiness and associated factors among medical college students of the Andaman and Nicobar islands. METHODS AND MATERIALS A cross-sectional study was conducted among 315 medical students of the A and N islands. The happiness of students was measured using the Oxford Happiness Questionnaire. Chi-square test and multiple logistic regression were used for data analysis. RESULTS Among all the students, 42.5% were happy. There was a significant association between happiness and the relationship of students with family and friends, physical exercise, spiritual beliefs, the presence of stress, and traumatic events. The multiple logistic regression revealed that good relationship with friends increased the odds of happiness of students significantly with an adjusted odd ratio (OR) of 3.204 (1.641-6.257), whereas the presence of stress decreased the happiness of students significantly with an adjusted OR of 0.430 (0.254-0.730). CONCLUSION Good relations with friends emerged as a positive predictor of happiness, whereas stress emerged as a negative predictor of happiness among the students. Hence, human relationships, stress management, physical exercise or sports, and orientation to spiritual health should be given emphasis in the medical curriculum.

Appetite 2023; 180:106338. [PMID: 36210016 PMCID: PMC10479967 DOI: 10.1016/j.appet.2022.106338] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2022] [Revised: 09/30/2022] [Accepted: 10/01/2022] [Indexed: 11/06/2022]
Abstract
Socioeconomic status has been related to poorer eating behaviors, potentially due to feeling of lower status relative to peers. Despite experimental evidence that temporarily feeling of lower status can contribute to greater caloric intake, it remains unclear how feeling of lower social status relate to eating behavior in daily life. This study aimed to test whether lower subjective social status (SSS)-the feeling of having relatively lower social status-in American society and relative to college peers were related to daily food selection. A sample of 131 young adults (Mage = 20.3, SD = 0.8; 60% female; 46% Latinos; 34% European American; 15% Asian American; 5% of other ethnicities) reported their SSS in society and in college and completed 15 daily reports regarding the number of daily servings they had of fruits, vegetables, fried foods, fast foods, desserts, and sugary drinks. Multilevel models with days nested within individuals were used to test whether low SSS in society or college related to daily food intake. Next, we examined whether associations were driven by young adults' perceived stress and daily stressors. Analyses controlled for age, gender, ethnicity, family and personal income, and parents' education to test the unique associations between subjective status and food intake. Whereas SSS in society was not related to food intake, young adults with lower SSS in their college consumed fewer daily servings of healthy foods and more daily servings of high-fat/high-sugar foods. Although lower college SSS was related to greater perceived stress, perceived stress and daily stressors were consistently unrelated to daily food intake. Findings suggested that lower SSS in local environments (e.g., college) may impact young adults' daily food choices through processes beyond heightened stress.

Abstract
Background People’s quality of life diverges on their demographics, socioeconomic status, and social connections. Objective By taking both demographic and socioeconomic features into account, we investigated how quality of life varied on social networks using data from both longitudinal surveys and contact diaries in a year-long (2015-2016) study. Methods Our 4-wave, repeated measures of quality of life followed the brief version of the World Health Organization Quality of Life scale (WHOQOL-BREF). In our regression analysis, we integrated these survey measures with key time-varying and multilevel network indices based on contact diaries. Results People’s quality of life may decrease if their daily contacts contain high proportions of weak ties. In addition, people tend to perceive a better quality of life when their daily contacts are face-to-face or initiated by others or when they contact someone who is in a good mood or someone with whom they can discuss important life issues. Conclusions Our findings imply that both functional and structural aspects of the social network play important but different roles in shaping people’s quality of life.

Abstract
Background Quantifying the effects of personal health behaviors and environmental exposure on asthma flare-ups is a challenge. Most studies have focused on monitoring the symptoms and drug usage for relieving symptoms. In this study, we emphasize the need to understand how personal and environmental conditions are related to the occurrence of asthma symptoms. Methods We designed an online health diary platform to collect personal health behaviors from children, their parents and other adults with any allergic diseases including asthma, allergic rhinitis, atopic dermatitis and allergic conjunctivitis. The participants used mobile devices or computers to record their daily health-related activities such as sleep, exercise, diet, perception of air quality and temperature, and asthma symptoms. The participants also recorded secondhand smoke exposure and the time of activities, which were combined with ambient air quality measurements for calculating personal air pollution exposure. A generalized linear mixed model was used to estimate the effects of the factors. Results During the study period (January 2017–June 2017, and October 2017–September 2018), 132 participants provided 25,016 diary entries, and 84 participants had experienced asthma symptoms in 1458 diary entries. The results showed some different risk factors for the minors and adults. For minors, high-intensity exercise, contact with persons with influenza-like illness (ILI) and the perception of hot temperature and bad indoor air quality were associated with the occurrence of asthma episodes. The identified risk factors for the adult participants included having dehumidifiers at home, exposure to secondhand smoke, having bad sleep quality, contact with persons with ILI, not eating fruit and seafood, perceiving cold temperature, bad quality of indoor and outdoor air, and exposure to high concentration of ozone. Conclusions The revealed personal risk factors and perceptions of air quality and temperature may provide guidance on behavioral change for people susceptible to asthma to help control acute onset and severe exacerbation of asthma flare-ups.

Abstract
OBJECTIVES Several common supplements are used by a significant number of patients affected by gastrointestinal (GI) disorders to improve symptoms and quality of life. We investigated the impact of GI symptom improvement with the use of fiber, STW 5, probiotics, and peppermint oil in relation to overall GI pain and quality of life via an online survey. DESIGN We used a cross-sectional, descriptive, correlation design. A Qualtrics online survey was utilized to collect data from January to June 2013 through various websites. Areas evaluated included participant demographics, use of supplements, and gastrointestinal symptom severity. RESULTS The rate of supplement use among patients with GI disorders was high (90% in past year) and consultation with healthcare providers was reported by 80%. Participants who completed the survey (n = 68) reported a strong correlation between GI symptom severity and overall quality of life (r2 = 0.8682, p < 0.001). The use of fiber improved GI symptom severity while both STW 5 and probiotics were linked to specific improvements. CONCLUSIONS Persons with chronic GI disorders often choose the complementary use of common supplements to mitigate GI symptoms and consult with their healthcare providers frequently. The use of STW 5 and probiotics specifically is linked to overall reduction in GI symptoms and improvement of quality of life.

Abstract
OBJECTIVES This paper examines how people express personal mood concurrently with those connected with them by one or two degrees of separation. DESIGN Participatory cohort study. SETTING Online contact diary. PARTICIPANTS 133 participants kept online diaries for 7 months in 2014, which included 127 455 contacts with 12 070 persons. MAIN OUTCOME MEASURES Diary keepers rated a contacted person's mood during each specific contact, as well as the strength of ties between any pairs of such contacted persons. Such rich information about ties and contacts enable us to construct a complete contact network for each diary keeper, along with the network members' mood and tie strength. We calculate one's overall mood by that person's average mood score during the study period and take the shortest path between any given pair of contacted persons as the degree of separation. We further assume that two connecting persons in a contact network have made contact with each other during the study period, which allows us to examine whether and how personal moods occur concurrently within these contact networks. RESULTS Using mixed-effects models while controlling for covariates at individual, tie and contact levels, we show that personal mood score positively and significantly correlates with the average mood among those directly tied to the person. The same effect remains positive and significant for those connected to the person by two degrees, although the effect size is reduced by about one-half. The mood of anyone separated by more than two degrees is statistically irrelevant. CONCLUSIONS Applying network perspectives and rich data at both tie and contact levels to inquiries about subjective well-being, the current study sheds new light on how an improved diary approach can help explain the sophisticated ways in which individuals express their personal moods concurrently during social interactions in everyday life, contact by contact.

Understanding the Positive Associations of Sleep, Physical Activity, Fruit and Vegetable Intake as Predictors of Quality of Life and Subjective Health Across Age Groups: A Theory Based, Cross-Sectional Web-Based Study. Front Psychol 2018; 9:977.

Abstract
Background: Due to the increase in unhealthy lifestyles and associated health risks, the promotion of healthy lifestyles to improve the prevention of non-communicable diseases is imperative. Thus, research aiming to identify strategies to modify health behaviors has been encouraged. Little is known about addressing multiple health behaviors across age groups (i.e., young, middle-aged, and older adults) and the underlying mechanisms. The theoretical framework of this study is Compensatory Carry-Over Action Model which postulates that different health behaviors (i.e., physical activity and fruit and vegetable intake) are interrelated, and they are driven by underlying mechanisms (more details in the main text). Additionally, restful sleep as one of the main indicators of good sleep quality has been suggested as a mechanism that relates to other health behaviors and well-being, and should therefore also be investigated within this study. The present study aims to identify the interrelations of restful sleep, physical activity, fruit and vegetable intake, and their associations with sleep quality as well as overall quality of life and subjective health in different age groups. Methods: A web-based cross-sectional study was conducted in Germany and the Netherlands. 790 participants aged 20–85 years filled in the web-based baseline questionnaire about their restful sleep, physical activity, fruit and vegetable intake, sleep quality, quality of life, and subjective health. Descriptive analysis, multivariate analysis of covariance, path analysis, and multi-group analysis were conducted. Results: Restful sleep, physical activity, and fruit and vegetable intake were associated with increased sleep quality, which in turn was associated with increased overall quality of life and subjective health. The path analysis model fitted the data well, and there were age-group differences regarding multiple health behaviors and sleep quality, quality of life, and subjective health. Compared to young and older adults, middle-aged adults showed poorest sleep quality and overall quality of life and subjective health, which were associated with less engagement in multiple health behaviors. Conclusion: A better understanding of age-group differences in clustering of health behaviors may set the stage for designing effective customized age-specific interventions to improve health and well-being in general and clinical settings. Trial Registration: A clinical trial registration was conducted with ClinicalTrials.gov (NCT01909349) https://clinicaltrials.gov/ct2/show/NCT01909349.

Abstract
Background Epidemiological studies on influenza have focused mostly on enhancing vaccination coverage or promoting personal hygiene behavior. Few studies have investigated potential effects of personal health behaviors and social contacts on the risk of getting influenza-like illness (ILI). Objective Taking advantage of an online participatory cohort, this study aimed to estimate the increased risk of getting ILI after contact with infected persons and examine how personal health behaviors, weather, and air pollution affect the probability of getting ILI. Methods A Web-based platform was designed for participants to record daily health behaviors and social contacts during the influenza season of October 1, 2015 to March 31, 2016, in Taiwan. Data on sleep, diet, physical activity, self-reported ILI, and contact with infected persons were retrieved from the diaries. Measurements of weather and air pollutants were used for calculating environmental exposure levels for the participants. We fitted a mixed-effects logistic regression model to the daily measurements of the diary keepers to estimate the effects of these variables on the risk of getting ILI. Results During the influenza season, 160 participants provided 14,317 health diaries and recorded 124,222 face-to-face contacts. The model estimated odds ratio of getting ILI was 1.87 (95% CI 1.40-2.50) when a person had contact with others having ILI in the previous 3 days. Longer duration of physical exercise and eating more fruits, beans, and dairy products were associated with lower risk of getting ILI. However, staying up late was linked to an elevated risk of getting ILI. Higher variation of ambient temperature and worse air quality were associated with increased risk of developing ILI. Conclusions Developing a healthier lifestyle, avoiding contact with persons having ILI symptoms, and staying alert with respect to temperature changes and air quality can reduce the risk of getting ILI.

Abstract
PURPOSE Nutrition plays a major role in physical and mental health. The aim of this study was to evaluate the relationships between happiness and fruit and vegetable intake as well as eating breakfast in students. METHODS In this cross-sectional web-based study, all students of Qazvin University of Medical Sciences in Iran who attended course classes were invited to participate in the study. Five hundred forty-one students filled out the web-based questionnaire which included questions related to measurement of happiness, breakfast, fruit and vegetable consumption and socio-economic and demographic information. Analysis of covariance was used to assess the relationship between happiness and breakfast, fruit and vegetable consumption by adjustments for covariates. RESULTS Measure of happiness was positively associated with eating breakfast, number of meals eaten daily and the amount of fruit and vegetable consumption (P values were <0.001, 0.008, 0.02, and 0.045 respectively). Students who ate breakfast every day, more than 8 servings of fruit and vegetables daily, and had 3 meals in addition to 1-2 snacks per day had the highest happiness score. CONCLUSION Healthier behavior pattern was associated with higher happiness scores among medical students.

Abstract
Past studies have shown that personal subjective happiness is associated with various macro- and micro-level background factors, including environmental conditions, such as weather and the economic situation, and personal health behaviors, such as smoking and exercise. We contribute to this literature of happiness studies by using a geospatial approach to examine both macro and micro links to personal happiness. Our geospatial approach incorporates two major global datasets: representative national survey data from the International Social Survey Program (ISSP) and corresponding world weather data from the National Oceanic and Atmospheric Administration (NOAA). After processing and filtering 55,081 records of ISSP 2011 survey data from 32 countries, we extracted 5,420 records from China and 25,441 records from 28 other countries. Sensitivity analyses of different intervals for average weather variables showed that macro-level conditions, including temperature, wind speed, elevation, and GDP, are positively correlated with happiness. To distinguish the effects of weather conditions on happiness in different seasons, we also adopted climate zone and seasonal variables. The micro-level analysis indicated that better health status and eating more vegetables or fruits are highly associated with happiness. Never engaging in physical activity appears to make people less happy. The findings suggest that weather conditions, economic situations, and personal health behaviors are all correlated with levels of happiness.
