Long-term weight loss success and the health behaviours of adults in the USA: findings from a nationally representative cross-sectional study.

ABSTRACT:

Objective

To describe the relationship between long-term weight loss (LTWL) success and lifestyle behaviours among US adults.

Design

Serial cross-sectional data from National Health and Nutrition Examination Survey cycles 2007-2014.

Setting and participants

Population-based nationally representative sample. The analytic sample included 3040 adults aged 20-64 years who tried to lose weight in the past year.

Measures

Participants were grouped into five LTWL categories (<5%, 5%-9.9%, 10%-14.9%, 15%-19.9% and ≥20%). Lifestyle-related behaviours included the following: alcohol intake, physical activity, smoking, fast-food consumption, dietary quality (Healthy Eating Index (HEI)) and caloric intake. Multivariable regression was employed adjusting for age, sex, race/ethnicity, marital status, education, household income and size, current body mass index and self-reported health status.

Results

Individuals in the 15%-19.9% LTWL group differed significantly from the reference group (<5% LTWL) in their physical activity and dietary quality (HEI) but not caloric intake. Specifically, they had a higher HEI score (β=3.19; 95% CI 0.39 to 5.99) and were more likely to meet physical activity guidelines (OR=1.99; 95% CI 1.11 to 3.55). In comparison, the ≥20% LTWL group was significantly more likely to smoke (OR=1.63; 95% CI 1.03 to 2.57) and to consume lower daily calories (β=-202.91; 95% CI -345.57 to -60.25) than the reference group; however, dietary quality and physical activity did not significantly differ.

Conclusion

Among a national sample of adults, a higher level of LTWL success does not necessarily equate to healthy weight loss behaviours. Future research should attempt to design interventions aimed at facilitating weight loss success while encouraging healthy lifestyle behaviours.

Project description:BackgroundSurveys have found concerningly high levels of agreement that the United States will experience civil war soon. This study assesses variation in expectation of and perceived need for civil war with respondent sociopolitical characteristics, beliefs, firearm ownership, and willingness to engage in political violence.MethodsFindings are from Wave 2 of a nationally representative annual longitudinal survey of members of the Ipsos KnowledgePanel, conducted May 18-June 8, 2023. All respondents to 2022's Wave 1 who remained in KnowledgePanel were invited to participate. Outcomes are expressed as weighted proportions and adjusted prevalence differences, with p-values adjusted for the false discovery rate and reported as q-values.ResultsThe completion rate was 84.2%; there were 9385 respondents. After weighting, half the sample was female (50.7%, 95% CI 49.4%, 52.1%); the weighted mean (± standard deviation) age was 48.5 (25.9) years. Approximately 1 respondent in 20 (5.7%, 95% CI 5.1%, 6.4%) agreed strongly or very strongly that "in the next few years, there will be civil war in the United States." About 1 in 25 (3.8%, 95% CI 3.2%, 4.4%), and nearly 40% (38.4%, 95% CI 32.3%, 44.5%) of those who strongly or very strongly agreed that civil war was coming, also agreed strongly or very strongly that "the United States needs a civil war to set things right." Expectation of and perceived need for civil war were higher among subsets of respondents who in Wave 1 were more willing than others to commit political violence, including MAGA Republicans, persons in strong agreement with racist beliefs or statements of the potential need for violence to effect social change, persons who strongly approved of specified extreme right-wing political organizations and movements, firearm owners who purchased firearms in 2020 or later, and firearm owners who carried firearms in public all or nearly all the time.ConclusionsIn 2023, the expectation that civil war was likely and the belief that it was needed were uncommon but were higher among subsets of the population that had previously been associated with greater willingness to commit political violence. These findings can help guide prevention efforts.

Project description:BackgroundCurrent conditions in the USA suggest an increasing risk for political violence. Little is known about the prevalence of beliefs that might lead to political violence, about support for and personal willingness to engage in political violence, and about how those measures vary with individual characteristics, lethality of violence, political objectives that violence might advance, or specific populations as targets.MethodsThis cross-sectional US nationally representative survey was conducted on May 13 to June 2, 2022, of adult members of the Ipsos KnowledgePanel. Outcomes are weighted, population-representative proportions of respondents endorsing selected beliefs about American democracy and society and violence to advance political objectives.ResultsThe analytic sample included 8620 respondents; 50.5% (95% confidence interval (CI) 49.3%, 51.7%) were female; and weighted mean (± standard deviation) age was 48.4 (± 18.0) years. Nearly 1 in 5 (18.9%, 95% CI 18.0%, 19.9%) agreed strongly or very strongly that "having a strong leader for America is more important than having a democracy"; 16.2% (95% CI 15.3%, 17.1%) agreed strongly or very strongly that "in America, native-born white people are being replaced by immigrants," and 13.7% (95% CI 12.9%, 14.6%) agreed strongly or very strongly that "in the next few years, there will be civil war in the United States." One-third of respondents (32.8%, 95% CI 31.7%, 33.9%) considered violence to be usually or always justified to advance at least 1 of 17 specific political objectives. Among all respondents, 7.7% (95% CI 7.0%, 8.4%) thought it very or extremely likely that within the next few years, in a situation where they believe political violence is justified, "I will be armed with a gun"; 1.1% (95% CI 0.9%, 1.4%) thought it very or extremely likely that "I will shoot someone with a gun." Support for political violence and for the use of firearms in such violence frequently declined with increasing age, education, and income.ConclusionsSmall but concerning proportions of the population consider violence, including lethal violence, to be usually or always justified to advance political objectives. Prevention efforts should proceed urgently based on the best evidence available.

Project description:ObjectivesIn South Africa, the Control of Tobacco and Electronic Delivery Systems Bill seeks to regulate e-cigarettes as tobacco products, including their advertising, promotion and sponsorship. Population data on e-cigarette advertising in South Africa are needed to inform public health programs, practice and policy. We examined self-reported e-cigarette advertising exposure during 2017. DESIGN: Cross-sectional.SettingHousehold-based survey.Participants3063 individuals who participated in the 2017 South African Social Attitudes survey, a nationally representative, in-person survey of the non-institutionalised civilian adult population aged ≥16 years EXPOSURE: 'In the past 12 months, have you seen advertisements or promotions for e-cigarettes (including e-shisha, e-pipe) on any of the following media: newspapers/magazines, billboards, in the malls or any other source?'Main outcomesBeliefs and attitudes regarding e-cigarettes.FindingsParticipants' mean age was 37.7 years. Overall, 20.1% reported exposure to e-cigarette advertisements. By age, exposure was most prevalent among those aged 16-19 years (24.6%). Top sources of exposure among those exposed were stores, 40.7%; malls, 30.9%; and television, 32.5%. Of those aware of e-cigarettes, 61.2% believed 'e-cigarette advertisements and promotion may make adolescents think of smoking traditional cigarettes'; 62.7% believed that 'e-cigarette advertisements and promotions may make ex-smokers think of starting smoking cigarettes again'; and 59.5% supported the statement that 'e-cigarette smoking should be banned indoors just as traditional cigarette smoking'. Notably, teens aged 16-19 reported the lowest prevalence (49.0%) of those believing that 'e-cigarette advertisements and promotion may make adolescents think of smoking traditional cigarettes', whereas this percentage was highest among those aged 55-64 years (73.2%).ConclusionComprehensive regulatory efforts are needed to address e-cigarette advertising, marketing and sponsorship in order to protect public health. The urgent enactment of the new tobacco control legislation, The Control of Tobacco Products and Electronic Delivery Systems Bill, can help reduce youth exposure to e-cigarette advertising in South Africa.
