Abstract Background The relation between cigarette smoking and metabolic syndrome (MetS) remains unclear, and previous studies focusing on MetS are limited in sample size. We investigated the association between life-course smoking and MetS with independent discovery and replication samples. Methods Preliminary analysis utilized data from an annual cross-sectional survey of 15,222 participants aged ≥ 60 years in Tianjin, China. Suggestive associations were followed-up in 8565 adults from the China Health and Nutrition Survey. MetS was identified according to the criteria of the Chinese Diabetes Society in 2013. Life-course smoking was assessed by a comprehensive smoking index (CSI), based on information on smoking intensity, duration, and time since cessation across life-course, collected through standard questionnaires. Participants were divided into four groups: non-smokers; and the tertiles of CSI in ever smokers. Multivariable logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for the association between life-course smoking and MetS. Results In the discovery sample, ORs of MetS were 2.01 (95%CI: 1.64–2.47) and 1.76 (95%CI: 1.44–2.16) for smokers in the highest and second tertile of CSI compared with never smokers. Potential interaction was shown for age, with increased ORs for MetS associated with smoking limited to individuals who aged < 70 years (Pinteraction = 0.015). We were able to replicate the association between cigarette smoking and MetS in an independent adult sample (second tertile vs. never: OR = 1.30, 95%CI: 1.04–1.63). The interaction of smoking with age was also replicated. Conclusions Life-course cigarette smoking is associated with an increased odds of MetS, especially among individuals who aged < 70 years.

Dose Response Effect

BackgroundThe association between cigarette smoking and psychosis remains unexplained, but could relate to causal effects in both directions, confounding by socioeconomic factors, such as ethnicity, or use of other substances, including cannabis. Few studies have evaluated the association between cigarettes and psychotic experiences (PEs) in diverse, inner-city populations, or relationships with number of cigarettes consumed.MethodsWe assessed associations and dose–response relationships between cigarette smoking and PEs in a cross-sectional survey of household residents (n = 1680) in South East London, using logistic regression to adjust for cannabis use, other illicit substances, and socioeconomic factors, including ethnicity.ResultsWe found association between any PEs and daily cigarette smoking, which remained following adjustment for age, gender, ethnicity, cannabis and use of illicit stimulant drugs (fully adjusted odds ratio 1.47, 95% confidence interval 1.01–2.15). Fully adjusted estimates for the association, and with number of PEs, increased with number of cigarettes smoked daily, implying a dose–response effect (p = 0.001 and <0.001, respectively). Odds of reporting any PEs in ex-smokers were similar to never-smokers.ConclusionsIn this diverse epidemiological sample, association between smoking and PEs was not explained by confounders such as cannabis or illicit drugs. Daily cigarette consumption showed a dose–response relationship with the odds of reporting PEs, and of reporting a greater number of PEs. There was no difference in odds of reporting PEs between ex-smokers and never-smokers, raising the possibility that the increase in PEs associated with smoking may be reversible.

Purpose. To examine the relationships between worksite interpersonal influences and smoking and quitting behavior among adolescent workers. Design. The cross-sectional survey assessed factors influencing tobacco use behavior. Setting. During the fall of 1998, data were collected from 10 grocery stores in Massachusetts that were owned and managed by the same company. Subjects. Eligible participants included 474 working adolescents ages 15 to 18. Eighty-three percent of workers (n = 379) completed the survey. Measures. The self-report questionnaire assessed social influences, social norms, social support, friendship networks, stage of smoking and quitting behavior, employment patterns, and demographic factors. Results. Thirty-five percent of respondents were never smokers, 21% experimental, 5% occasional, 18% regular, and 23% former smokers. Using analysis of variance (ANOVA), results indicate that regular smokers were 30% more likely than experimental or occasional smokers to report coworker encouragement to quit (p = .0002). Compared with regular smokers, never smokers were 15% more likely to report greater nonacceptability of smoking (p = .01). χ2 tests of association revealed no differences in friendship networks by stage of smoking. Conclusions. These data provide evidence for the need to further explore social factors inside and outside the work environment that influence smoking and quitting behavior among working teens. Interpretations of the data are limited because of cross-sectional and self-report data collection methods used in one segment of the retail sector.

Abstract The present study aimed to assess the associations of the stages of Fe deficiency (Fe deficiency without anaemia (ID) and Fe-deficiency anaemia (IDA)) and anaemia with metabolic syndrome (MetS) in Ecuadorian women. A cross-sectional study was conducted in 5894 women aged 20–59 years, based on data from the 2012 Ecuadorian National Health and Nutrition Survey. The sample was stratified by age. A χ2 test was used to assess the possible associations of ID, IDA and anaemia with MetS. The prevalence ratio (PR) for each stage of Fe deficiency and anaemia was estimated considering women without MetS as a reference. The total prevalence of MetS, ID, IDA and anaemia was 32⋅3 % (se 0⋅6), 6⋅2 % (se 0⋅3), 7⋅1 % (se 0⋅3) and 5⋅0 % (se 0⋅3), respectively. In women aged 20–29, 30–39 and 40–49 years, MetS was associated with a lower prevalence of ID (PR (95 % CI; P-value)): 0⋅17 (0⋅06, 0⋅46; P < 0⋅001), 0⋅69 (0⋅48, 0⋅99; P = 0⋅044) and 0⋅44 (0⋅29, 0⋅67; P < 0⋅001), respectively. In women aged 50–59 years, MetS was associated with IDA and anaemia (PR (95 % CI; P-value)): 0⋅12 (0⋅02, 0⋅96; P = 0⋅026) and 0⋅22 (0⋅07, 0⋅64; P = 0⋅002), respectively. In conclusion, Ecuadorian women of reproductive age with MetS have a lower prevalence of ID compared with those without MetS. Furthermore, the MetS and IDA coexist at the population level. These findings require an analysis from a dietary pattern approach, which could provide key elements for developing public policies that simultaneously address all forms of malnutrition.

AbstractObjectivesTo examine the relationship between cigarette smoking and a range of nutrient intakes and blood status indices in older people.DesignNational Diet and Nutrition Survey: cross-sectional survey of nationally representative sample of people aged 65 years and over.SettingMainland Britain during 1994/95.Subjects1191 people (619 male, 572 female) aged 65 years and over, of whom 920 were living in private households and 271 were living in institutions.ResultsCigarette smoking was inversely correlated with intakes of antioxidants and other micronutrients after adjustment for age, sex and domicile. Cigarette smoking was also inversely correlated with a number of antioxidant micronutrient status indices including plasma vitamin C and the carotenoids (but not vitamin E status indices), and with other micronutrient status indices, including plasma pyridoxal phosphate, red cell and serum folate, after adjustment for age, sex, domicile and the corresponding nutrient intake. Previous cigarette smoking or cigar/pipe smoking was not generally associated with lower nutrient intakes or status indices, however, both current and previous cigarette smoking was associated with increased concentrations of acute phase indicators. Further adjustment for total energy intake and/or sociodemographic, health and drug usage variables attenuated only a few of the associations observed.ConclusionOlder people who smoke cigarettes are at increased risk of suboptimal antioxidant and other micronutrient intakes and status, but the lower intakes found in cigarette smokers only partly explain their reduced blood indices.

Metabolic Syndrome Components

Background: A growing body of evidence suggests that cigarette smoking can cause the onset of metabolic syndrome prior to cardiovascular diseases. Therefore, the objective of this study was to evaluate the relationship between smoking habit and metabolic syndrome components in an adult population from Maracaibo city, Venezuela. Methods: The Maracaibo City Metabolic Syndrome Prevalence Study is a descriptive, cross-sectional study with random and multi-stage sampling. In this sub-study, 2212 adults from both genders were selected. On the basis of their medical background, they were classified as smokers, non-smokers and former smokers. Metabolic syndrome was defined according to Harmonizing 2009 criteria, using population-specific abdominal circumference cut-off points. The association between risk factors was evaluated using a logistic regression model. Results: In the studied population, 14.8% were smokers, 15.4% were former smokers. In the multivariate analysis, the presence of metabolic syndrome (smokers: OR, 1.54; 95% CI, 1.11–2.14; p=0.010) and its components were related to cigarette smoking, with the exception of hyperglycemia. High blood pressure was inversely associated with current smoking status (smokers: OR, 0.70 (0.51–0.95); p=0.025). Conclusion: Cigarette smoking represents a related factor with metabolic syndrome, being associated with low high-density lipoprotein-cholesterol, increased abdominal circumference and elevated triacylglyceride levels. Former smokers did not present a greater risk for developing this metabolic disease when compared to non-smokers. The effect of avoiding this habit should be evaluated in future studies in our population.

Cigarette Packs

Abstract Introduction From May 20, 2017, cigarettes in the United Kingdom must be sold in standardized (plain) packaging. We explore postimplementation reactions to standardized cigarette packaging among never-smokers in Scotland, whether reactions vary in relation to permitted variations in pack structure, and whether reactions are associated with susceptibility. Aims and Methods A cross-sectional survey with 12–17-year-old never-smokers (n = 507) in Scotland, conducted November 2017–November 2018. Participants were shown one “regular” standardized cigarette pack (flip-top lid and straight-edged pack, similar to designs in Australia) and three standardized packs with varied pack structures (beveled-edges, slim pack, and shoulder box), which are permitted postimplementation in the United Kingdom. Participants rated each pack on eight five-point reaction measures (eg, attractiveness). Participants also indicated which pack, if any, they would choose. Smoking susceptibility was the outcome. Results The mean reaction scores for all four packs were mostly negative, however the shoulder box was consistently rated less negatively than the regular, slim, or beveled-edge packs. Most participants (87%) said they would not select any of the four packs, although susceptible participants were more likely to select one than nonsusceptible participants (25% vs. 7%; χ 2 = 29.70; p &lt; .001). For all four packs, not finding them off-putting was associated with susceptibility (Adjusted Odds Ratio range: 2.73–3.69), albeit only a minority of adolescents did not find each pack off-putting. Conclusions Adolescents have negative reactions to the standardized cigarette packs implemented in the United Kingdom, albeit permitted variations in structure can reduce the extent of negativity. Most reactions to standardized packaging had no association with susceptibility. Implications We provide the first empirical evidence that adolescents find the standardized cigarette packs implemented in the United Kingdom unappealing and that most pack reactions have no association with susceptibility among never-smokers, with the exception of the minority who did not think that they would put them off smoking. This suggests that the legislation is achieving one of its primary aims, to reduce the appeal of packaging. That permitted variations in pack structure (eg, shoulder boxes) somewhat reduce negative reactions suggests that the United Kingdom, and other countries introducing similar legislation, should ensure that all aspects of pack design are fully standardized.

Abstract Background Studies indicate an effect of smoking toward abdominal obesity, but few assess hip and waist circumferences (HC and WC) independently. The present study aimed to assess the associations of smoking status and volume smoked with HC and WC and their ratio in a population with low prevalence of obesity together with high prevalence of smoking. Methods We used cross-sectional survey data from 11 of a total 19 Norwegian counties examined in 1997–99 including 65,875 men and women aged 39–44 years. Analysis of associations were adjusted for confounding by socioeconomic position, health indicators, and additionally for BMI. Results Compared with never-smokers, when adjusting for confounders and in addition for BMI, mean HC remained lower while mean WC and waist-hip-ratio (WHR) were higher in current smokers. The finding of a lower HC and higher WHR level among smokers was consistent by sex and in strata by levels of education and physical activity, while the finding of higher WC by smoking was less consistent. Among current smokers, BMI-adjusted mean HC decreased whereas WC and WHR increased by volume smoked. Compared with current smokers, former smokers had higher BMI-adjusted HC, lower WHR and among women WC was lower. Conclusions The main finding in this study was the consistent negative associations of smoking with HC. In line with the hypothesis that lower percentage gluteofemoral fat is linked with higher cardiovascular risk, our results suggest that smoking impacts cardiovascular risk through mechanisms that reduce the capacity of fat storage in the lower body region.
