“…Our finding on the positive association between BMI and dieting attempts is in line with previous results [5,14,15,16,17,18,20,21,26,29,46,47,48,49,51,58,59,60,61,62,63,64,65]. People with obesity may have health-related reasons and other personal reasons to attempt to lose weight, but they may also have more social pressure to report dieting even though they have not necessarily dieted.…”

Self-Report Dieters: Who Are They?

Dieting attempts have become popular worldwide. Dieting, however, seems to have both positive and negative health-related consequences. So far, only a few studies have focused on the determinants of dieting in detail. This study explores the association between self-report dieting attempts and intentional weight loss (IWL) during the previous year and several demographic, lifestyle, health, and psychological factors in a cross-sectional study design using data from the representative Finnish Health 2000 Survey. The sample comprised 2147 men and 2378 women, aged 30–69. Information for potential determinants was assembled via health examinations, interviews, and questionnaires. Approximately 24% of the men and 39% of the women reported dieting attempts and 10% of the men and 15% of the women reported IWL. Dieting attempts were associated with younger age, education, BMI, formerly smoking, more favourable values in lifestyle variables, and unfavorable values in serum HDL and triglycerides, a worse sense of coherence, concerns about one’s appearance, and concerns about one’s health. Among men, diabetics and those sleeping ≤6 h a night more frequently reported dieting attempts and those with osteoarthritis reported IWL. Moreover, the gradient between BMI and dieting attempts was significantly stronger in men than in women. Men seem to attempt dieting when they have actual health-related reasons, while such reasons are not so strongly associated with dieting in women. These findings can be used for determining subpopulations with obesity and real weight-loss needs and, alternatively, subpopulations with normal weight unnecessarily attempting dieting.

“…Pesquisas retrospectivas sobre a prevalência do VHC na década de 1980 ao redor do mundo são escassas, principalmente na Amazônia brasileira (WHO, 2017). Comparando a hepatite C com as demais hepatites, como por exemplo as hepatites A e B, verificou-se o surgimento de novos registros no mundo, como descrito por Santos et al (1993) Sabendo que a infecção pela VHC em sua maioria apresenta-se de forma subclínica, seu diagnóstico em geral ocorre de forma acidental, quando da realização de exames de rotina (WHO, 2017), sendo um dos principais diagnósticos os testes sorológicos anti-VHC (POE et al, 2017), usando o ensaio imuoenzimático (ELISA), testes rápidos, ensaios eletroquimioluminescentes e quimioluminescente, além de pesquisa da partícula viral (NIEL et al, 2015). Vale ressaltar que o anti-VHC pode ser encontrado em todos os pacientes que tiveram contato com o VHC, mantendo-se reagente pelo resto da vida (NIEL et al, 2015;WHO, 2017).…”

Usuários de drogas injetáveis são populações de risco para a infecção pelos vírus das hepatites B (VHB) e C (VHC) podendo manifestar-se nas formas aguda ou crônica. Determinar o perfil sorológico das hepatites B e C em instituições para tratamento de dependentes químicos, na Amazônia oriental brasileira. O projeto foi desenvolvido entre 2020 a 2022 e incluiu internos de centros de recuperação, para tratamento antidrogas, maiores de 18 anos, de ambos os sexos. Foram coletadas 180 amostras de sangue, para a realização dos testes HBsAg, anti-HBc total, anti-HBs e anti-VHC por técnica de eletroquimioluminescência, 83,3% das amostras eram de indivíduos do sexo masculino; a média de idade era de 38±11,8 anos e a mediana de 37 anos. A soroprevalência não detectou amostras reagentes para o HBsAg; 6,1% eram anti-HBc/anti-HBs reagentes, indicando infecção pregressa pelo VHB; 2,8% eram anti-HBc reagente isolado, significando infecção recente ou pregressa pelo VHB; 19,4% reagente para anti-HBs isolado, indicativo de imunidade por vacina, 71,7% mostraram-se suscetíveis ao VHB e 0,5% reagente para anti-VHC. Ressalta-se a importância de estudos entre usuários de drogas para conhecer a situação das infecções pelo VHB e VHC e contribuir com informações epidemiológicas, aplicando ações de promoção e prevenção da saúde.

Prevalence of personal weight control attempts in adults: a systematic review and meta‐analysis

et al. 2016

SummaryThe purpose of this systematic review and meta‐analysis was to estimate the prevalence of personal weight control attempts (weight loss and/or maintenance) worldwide and to identify correlates, personal strategies used and the underlying motives. We included epidemiological/observational studies of adults (≥18 years) reporting prevalence of weight control attempts in the past‐year. Seventy‐two studies (n = 1,184,942) met eligibility criteria. Results from high quality studies showed that 42% of adults from general populations and 44% of adults from ethnic‐minority populations reported trying to lose weight, and 23% of adults from general populations reported trying to maintain weight annually. In general population studies, higher prevalence of weight loss attempts was observed in the decade of 2000–2009 (48.2%), in Europe/Central Asia (61.3%) and in overweight/obese individuals and in women (p < 0.01). Of the 37 strategies (grouped in 10 domains of the Oxford Food and Activity Behaviours Taxonomy) and 12 motives reported for trying to control weight, exercising and dieting (within the energy compensation and restraint domains, respectively) and wellbeing and long‐term health were the most prevalent. To our knowledge, this is the first systematic review to investigate weight control attempts worldwide. Key strategies and motives were identified which have implications for future public health initiatives on weight control.
