OBJECTIVE: Pedestrian-oriented zoning, including zoning code reforms (ZCR), may be especially beneficial to racially and economically segregated communities, which may lack built environment features that support physical activity. This study examined associations between racialized economic segregation, measured by quintiles of the Index of Concentration at the Extremes, and public transit (PTW) and active travel (ATW) to work, and whether associations were moderated by pedestrian-oriented zoning provisions and ZCR, respectively...

OBJECTIVE: The Supplemental Nutrition Assistance Program (SNAP) was modified to mitigate food insecurity faced by low-income families during the pandemic. These changes included enhancement of SNAP benefits via 2020 emergency allotments (EA). Despite the high food price inflation in 2022, 17 states ceased providing EA benefits by end of 2022. The objective of this research is to examine the impact of EA discontinuation on food insufficiency. METHODS: Using Household Pulse Survey data from December 2021-January 2023, SNAP participants (n = 57,556) from states that discontinued EA at some point during the study period and those from states that did not discontinue EA were included...

BACKGROUND: Precarious employment (PE) has been conceptualized as having a multidimensional nature, and research addressing this topic in Asian countries is scarce. This study examined the typologies of PE and their relationships with mental health among Korean workers. METHODS: From October 2020 to April 2021, the Korean Working Conditions Survey was conducted on Korean wageworkers (weighted N = 38,347), representative of the nation. With theory-based operationalization of PE, we identified typologies and classified workers through latent class analysis...

UNLABELLED: Installation of technologies to remove or deactivate respiratory pathogens from indoor air is a plausible non-pharmaceutical infectious disease control strategy. OBJECTIVE: We undertook a systematic review of worldwide observational and experimental studies, published 1970-2022, to synthesise evidence about the effectiveness of suitable indoor air treatment technologies to prevent respiratory or gastrointestinal infections. METHODS: We searched for data about infection and symptom outcomes for persons who spent minimum 20 h/week in shared indoor spaces subjected to air treatment strategies hypothesised to change risk of respiratory or gastrointestinal infections or symptoms...

BACKGROUND: The impact of increased fruit consumption on weight change remains a matter of debate. OBJECTIVE: This study aimed to evaluate the effects of interventions targeted at promoting fruit consumption and managing body weight in children and adolescents. METHODS: Four electronic databases, including PubMed, Web of science, Embase, and the Cochrane Library, were searched from January 1, 2000, to October 10th, 2023, to identify Randomized controlled trials (RCTs) that assessed changes in fruit consumption and obesity indicators...

OBJECTIVE: Public acceptability of bowel cancer screening programmes must be maintained, including if risk stratification is introduced. We aimed to describe and quantify preferences for different attributes of risk-stratified screening programmes amongst the UK population, focussing on who to invite for bowel screening. METHODS: We conducted a discrete choice experiment (DCE) including the following attributes: risk factors used to estimate bowel cancer risk (age plus/minus sex, lifestyle factors and genetics); personalisation of risk feedback; risk stratification strategy plus resource implications; default screening in the case of no risk information; number of deaths prevented by screening; and number experiencing physical harm from screening...

OBJECTIVE: Coronary heart disease has several risk factors that require a multifactorial community intervention approach in prevention efforts. Prevalence of coronary heart disease and its risk factors have been disproportionately high among American Indians. The objective of this study is to evaluate the impact of ambulatory activity levels on the development of coronary heart disease in this population. METHODS: Using pedometer data and other lifestyle and clinical factors from 2492 participants in the Strong Heart Family Study, we examined the associations of average daily step counts with incident coronary heart disease during an 18 to 20 year follow-up...

INTRODUCTION: Influenza is a preventable acute respiratory illness with a high potential to cause serious complications and is associated with high mortality and morbidity in the US. We aimed to determine the specific community-level vulnerabilities for different race/ethnic communities that are most predictive of influenza vaccination rates. METHODS: We conducted a machine learning analysis (XGBoost) to identify community-level social vulnerability features that are predictive of influenza vaccination rates among Medicare enrollees across counties in the US and by race/ethnicity...

BACKGROUND: Firearm violence represents a public health crisis in the United States. Yet, there is limited knowledge about how firearms are discussed in the context of mental health emergencies representing a major gap in the current research literature. This study addresses this gap by examining whether the content of mental health crisis text conversations that mention firearms differ from those that do not mention firearms in a large, unique dataset from a national crisis text line...

BACKGROUND: Physical activity can improve physical health for people living with mild cognitive impairment (MCI) and dementia and may have cognitive benefits. Identifying modifiable social factors inhibiting physical activity among this group is needed. We sought to examine the relationship between reported physical activity levels and social determinants of health (SDOH) in a population of older adults living with MCI or dementia. METHODS: This descriptive study included people with a diagnosis of MCI or dementia followed by Community Internal Medicine at Mayo Clinic (Rochester, Minnesota, United States), aged over 55 years, who had a clinic visit between June 1, 2019 and June 30, 2021 and had completed a SDOH questionnaire...

OBJECTIVE: In the context of mass incarceration and the opioid toxicity crisis in North America, there is a lack of data on the burden of opioid toxicity deaths in Black persons who experience incarceration. We aimed to describe absolute and relative opioid toxicity mortality for Black persons who experienced incarceration in Ontario, Canada between 2015 and 2020. METHODS: We linked data for all persons incarcerated in provincial correctional facilities and all persons who died from opioid toxicity in Ontario between 2015 and 2020, and accessed public data on population sizes...

PURPOSE: To understand racial disparities in germline cancer genetic testing and the role of prior knowledge, attitudes, and sources of information. METHODS: A cross-sectional analysis of the Health Information National Trends Survey 5 (HINTS 5) was conducted between February 24th and June 15th, 2020. The study aimed to investigate knowledge and receipt of genetic testing, attitudes toward the importance of genetic testing in preventing, detecting, and treating cancer, and information sources of genetic testing in the United States of America...

Inconsistent correlations of screen use with physical activity (PA) and social capital (SC) in youths have been observed in existing cross-sectional studies. This study aimed to elucidate associations among variables in screen use, PA, and SC domains during COVID-19, to improve the prediction and prevention of suboptimal health status in youths. An online survey based on the nationwide COVID-19 Impact on Lifestyle Change Survey (COINLICS) was conducted in China, and 10,082 youths reported their screen use, PA, and SC in the months immediately before, during, and after the COVID-19 lockdown...

OBJECTIVE: The opioid crisis in the United States continues essentially unabated, fueled by fentanyl contamination of the heroin supply and resulting in 79,770 reported opioid-involved overdose deaths in the calendar year 2022. To prevent another such crisis emerging, it is necessary to fully identify its root causes. METHODS: Despite the well-recognized role the pharmaceutical industry played in facilitating the crisis via the aggressive marketing of prescription opioids, several other less appreciated but perhaps more influential factors were also contributors, and the overall goal of this review is to ensure that these are not be lost to history in a concerted effort to blame opioid manufacturers and distributors...

Socio-economic inequalities in mental health problems are found in measures covering prevalence, treatment utilisation, and treatment helpfulness. However, whether these inequalities exist globally and what factors explain between-country variation is unclear. We use a nationally representative individual-level survey dataset (Wellcome Global Monitor, 2023) in 111 countries (N = 117,088) to test if socio-economic factors (household income, education), psycho-social factors (stigma perception, trust in health professionals) and country-level factors (GDP, Gini, health expenditure) predict (1) self-reported lifetime prevalence of anxiety and depression symptomology, (2) treatment utilisation and (3) perceived treatment helpfulness talking to a mental health professional and taking prescribed medication...

OBJECTIVES: This study provided estimates of cancer incidence rate and onset age by Socio-demographic Index (SDI) regions and gender from 2020 to 2040, aiming to clarify the long-term patterns of future cancer onset. METHOD: Based on the incidence data from the Global Burden of Diseases (GBD) 2019 study, we constructed the Bayesian age-period-cohort model to calculate the age-standardized incidence rates (ASIR) of cancers from 2020 to 2040. Using the average annual percentage change (AAPC) to quantify the trends of ASIR and the onset age...

OBJECTIVE: Using cross-sectional data from the 2018 Health Survey for England, this study describes the types of impairment reported by people with chronic conditions and the association of chronic conditions and impairments with physical activity(PA). METHODS: Participants self-reported the presence of seven chronic health conditions (diabetes; stroke/ischemic heart disease; hypertension; chronic obstructive pulmonary disease (COPD); asthma; arthritis/rheumatism/fibrositis; back problems), 11 types of impairment (vision, hearing, mobility, dexterity; learning; memory; mental health; stamina; social or behavioural; other; none); and their PA using the International Physical Activity Questionnaire...

Serious Psychological Distress (SPD) and prenatal exposure to substances are associated with adverse outcomes for pregnant individuals and their developing offspring. This study aims to examine the relationship between SPD and quantity, or frequency of substance use among pregnant women in the United States (US). Descriptive and negative binomial regression analyses of the 2015-2019 National Survey on Drug Use and Health (NSDUH) were conducted among 3373 pregnant women (18 to 44 years old) to examine the association between SPD and (1) average number of cigarettes smoked in the past 30 days, (2) number of days of binge drinking in the past 30 days, and (3) number of days of cannabis use in the past 30 days...

BACKGROUND: The relationship between age at menarche and metabolic dysfunction-associated fatty liver disease remains largely not clear. The objective of this study was to examine the association between age at menarche (AAM) and metabolic dysfunction-associated fatty liver disease (MAFLD) in Chinese women and whether any observed associations were mediated by early adulthood adiposity. METHODS: The cross-sectional study included 46,873 Chinese women, aged 30-79 from baseline data of the China Multi-Ethnic Cohort study...

INTRODUCTION: While there is increasing interest in the use of cannabis to manage a range of health-related symptoms, little is known about trends in recent cannabis use with respect to various health conditions. METHODS: We examined data from a US representative sample of noninstitutionalized adults age ≥ 18 from the 2015-2019 National Survey on Drug Use and Health (N = 214,505). We estimated the pooled prevalences followed by linear time trends, overall, and by disability (i...
