Associations Between Childhood Trauma and Tobacco Use Outcomes in Adults after Overnight Abstinence.

Childhood trauma is known to be associated with nicotine dependence, yet limited smoking outcomes have been examined and few studies have assessed associations between specific trauma subscales and smoking. Additionally, sex differences in trauma-smoking relations are understudied. This study examined associations between childhood trauma and several smoking-related outcomes in adults who smoke after overnight abstinence. People who smoke (N = 205) completed self-report and biochemical assessments evaluating childhood trauma, affect, nicotine dependence, smoking urges, withdrawal, and plasma cortisol and cotinine levels. Smoking outcomes were compared between those with and without a history of moderate to severe childhood trauma among the total sample and by sex. Relative to those with no to minimal abuse, those with moderate to severe abuse had higher negative affect, withdrawal severity, and plasma cotinine levels. Exploratory analyses revealed that women were more likely than men to have urges to smoke for negative reinforcement and have higher withdrawal severity, but no interactions between abuse group and sex were observed. Examining specific trauma subscales, the moderate to severe emotional abuse group had more severe nicotine dependence, negative affect, and withdrawal compared to the no to minimal group. The moderate to severe sexual abuse group had more severe nicotine dependence and withdrawal compared to the no to minimal group. Exposure to childhood trauma is associated with more severe nicotine dependence, negative affect, withdrawal, and higher plasma cotinine levels. Findings also indicate that different types of trauma may differentially affect smoking behaviors. This study of adults who smoke finds that childhood trauma history may be a marker for smoking susceptibility and suggests that individuals with experiences of emotional and sexual abuse may require targeted forms of smoking cessation interventions. Moreover, findings suggest that smoking risks may differ for men and women. Findings inform public health interventions intended to reduce cigarette use in individuals with exposure to childhood trauma.

The effects of planned education given to parents on smoking in the home environment and passive exposure of children aged 0–5: A quasi-experimental pre-post intervention study from Turkey

PurposeThis study was carried out to determine the effects of planned education given to parents on smoking status at home and on children's passive smoking exposure. Design and methodsThis quasi-experimental study was conducted with the inclusion of 40 parents with at least one child between the ages of 0 and 5 and smoking in their homes, who were registered at a Family Health Center in a city center in the Central Anatolia Region of Turkey, from 1 September 2019 to 30 June 2020. The data of the study were collected using Participant Screening Form, a Personal Information Form, the Fagerstrom Test for Nicotine Dependence, a Smoking Behaviors and Precautions at Home Form, and a Measurement and Follow-up Form. The collected data were analyzed using the SPSS 23.0 package software. ResultsIn the follow-ups after the planned smoking cessation training given to the parents, the carbon monoxide measurements at their homes decreased significantly throughout the four follow-ups, the number of parents who presented to the smoking cessation outpatient clinic increased, and the number of smoking parents decreased (p < 0.05). ConclusionsIt was concluded that the planned education that was given to smoker parents reduced the smoking rates of the parents, lowered the carbon monoxide values measured in their home environments, and thus, it was effective in reducing the passive exposure of their children at the ages of 0 to 5 years to cigarette smoke. Practice implicationsParents who are addicted to cigarettes should be encouraged not to smoke at home, and homes should be included in closed environments where smoking is prohibited.

Cigarette smoking in childhood and risk of all-cause and cause-specific mortality in adulthood.

This study was aimed to examine the association between cigarette smoking in childhood and mortality in adulthood, and the impact of non-smoking duration among smokers who subsequently quit smoking. We used data from 472,887 adults aged 18-85 years examined once in the US National Health Interview Survey in 1997-2014, which was linked to mortality data from the National Death Index up to 31 December 2015. Cigarette smoking status in childhood (age 6 to 17 years) and adulthood (age 18 to 85 years) was self-reported using a standard questionnaire at the time of participation in the survey. The vital status of participants due all-causes, cardiovascular disease (CVD), cancer and chronic lower respiratory diseases was obtained using mortality data from the National Death Index. During the mean follow-up of 8.75 years, compared with never smoking in childhood and adulthood, the risk of all-cause mortality among current adult smokers decreased slightly according to increasing age at smoking initiation: hazard ratios (HRs; 95% confidence intervals, CIs) were 2.54 (2.24-2.88) at age of 6-9 years, 2.44 (2.31-2.57) at age of 10-14 years, and 2.21 (2.12-2.31) at age of 15-17 years. Smoking cessation before the age of 30 years was not associated with increased risk of all-cause and cause-specific mortality (all p > 0.05) compared to never smoking. Mortality risk was higher in individuals who started smoking at an earlier age in childhood. Inversely, smoking cessation before the age of 30 years was not associated with an increased risk of mortality compared to never smoking.

Parents' Knowledge and Perception of Child Abuse and Neglect in the Eastern Province of Saudi Arabia.

Child maltreatment is a crucial issue worldwide that has negative consequences for children and their families. Inability to distinguish between traditional corporal punishment and abuse is part of the problem. To assess parents' knowledge and perception of child maltreatment and investigate the factors that influence their awareness. This cross-sectional study recruited parents with at least one child aged <18 years. Data were collected using a self-administrated online questionnaire. Participants were categorized into two groups based on the median knowledge score. A total of 447 participants completed the questionnaire, of which 62% were female and the average age was 37 years. Almost two-thirds of the respondents (60.6%) consider child abuse and neglect (CAN) to be a common problem in Saudi Arabia. Only 53% had good knowledge of CAN, and more than one-third were unaware of the hotline number available to report any CAN. Almost half of the participants did not consider refusing childhood immunization or smoking in front of children to be a form of CAN. Logistic regression showed that higher education and family income levels were significantly associated with good knowledge (P = 0.013 and 0.003, respectively). While most parents consider CAN to be a common problem in Saudi Arabia, they do not have adequate knowledge of what constitutes emotional abuse and neglect. These findings highlight the need for community-based education programs to increase parents and caregivers' awareness of child rights.

Parent Support Relationship with Smoking Behavior

This study aims to determine the relationship between parental support and school children's smoking behavior. This research method uses descriptive correlational research with a cross-sectional approach. The study's results based on class and age showed that 22 students, with a percentage of 73.3%, had supportive parental social support, and 16 students, with a rate of 53.3%, had terrible smoking behavior. The P value of parents' social support with smoking behavior is 0.207. In conclusion, it shows no relationship between parental consent and school children's smoking behavior.&#x0D; &#x0D; Keywords: Parents' Social Support, Smoking Behavior, Elementary School Students

A network approach to the symptom-level associations between smoking and posttraumatic stress disorder (PTSD) among young adults exposed to childhood sexual abuse.

Previous empirical literature has examined the associations between childhood sexual abuse (CSA) exposure, posttraumatic stress disorder (PTSD), and smoking. However, few studies examined symptom-level associations between smoking and PTSD among CSA victims. Thus, the aims of this study were 1) to explore symptom-level associations between smoking and PTSD among combustible cigarette (CC) and electronic cigarette (EC) users exposed to CSA and 2) to compare the differences manifested in two network structures between EC and CC users with CSA experiences. This cross-sectional study covers all 63 universities and colleges in Jilin province, China, from October 26 to November 18, 2021. A total of 117 769 students participated in this study, while 3479 young adults were exposed to CSA (3.62%, 95% CI = 3.50%-3.73%). Childhood sexual abuse, PTSD, and smoking symptoms were measured using the Childhood Trauma Questionnaire-Short Form (CTQ-SF), 10-item Trauma Screening Questionnaire (TSQ-10), and the 6-item Fagerstrom Test for Nicotine Dependence (FTND-6), respectively. In addition, network analysis was applied to analyse psychopathological symptoms between EC and CC users with CSA experiences. Both the edges and centralities were computed, and the network properties were compared among the two groups. Four symptoms of PTSD (i.e. emotional cue reactivity, hypervigilance, nightmares, and difficulty concentrating) were both central and bridge symptoms between PTSD and smoking among EC and CC users with CSA experiences. Moreover, compared with CC users with CSA, there were significantly stronger associations between "nightmares" - "difficulty with restrictions" and "irritability / anger" - "more during wake up" among young EC users with CSA. The four symptoms (i.e. emotional cue reactivity, hypervigilance, nightmares, and difficulty concentrating) were keystones for treatments or interventions targeting these CSA victims with PTSD and smoking symptoms. Increasing efforts should be taken to restrict morning smoking among EC users with CSA. In addition, target interventions and strategies founded on these core symptoms and associations should be implemented to relieve the comorbid PTSD and smoking in EC and CC users with CSA experiences.

Childhood Cigarette Smoking and Risk of Chronic Obstructive Pulmonary Disease in Older U.S. Adults.

Rationale: It is not certain the extent to which childhood smoking adds chronic obstructive pulmonary disease (COPD) risk independent of lifetime cigarette exposure. Objectives: We examined the association between age started smoking cigarettes regularly, current smoking status, smoking history, and risk of COPD. Methods: Cross-sectional survey of U.S. adults ⩾40 years old in the 2020 National Health Interview Survey. Respondents who were ever cigarette smokers were asked when they began smoking regularly. Multivariable analysis assessed self-report of COPD diagnosis as a function of age started smoking (<15 yr vs. ⩾15 yr) adjusting for current smoking, cigarette pack-years, and covariates. Measurements and Main Results: Overall, 7.1% reported that they had COPD, 2.6% for never-smokers compared with 23.1% and 11.6% for smoking onset <15 and ⩾15 years, respectively. Persons who began smoking regularly at <15 years of age had higher pack-years of smoking (median, 29 vs. 15, respectively), and higher smoking intensity (median, 20 cigarettes/d for <15 yr vs. 10 cigarettes/d for ⩾15 yr for current smokers). In the multivariable analysis, the relative risk for COPD among childhood smokers was 1.41 (95% confidence interval, 1.22-1.63) compared with later-onset smokers. Substituting smoking duration for pack-years confounded the association between current smoking and COPD but did not change the childhood smoking estimate. In a stratified analysis, higher risk for childhood smoking was found at all current smoking intensity levels. Conclusions: Among adults aged ⩾40 years, one-fifth of childhood smokers have COPD. Lifetime cigarette smoking explained some but not all of the higher risk. If replicated, this suggests a lung development window of enhanced vulnerability to cigarette smoking.

Eliminating children's tobacco smoke exposure: a pathway to bioverified abstinence among low-income maternal smokers in the Babies Living Safe and Smokefree (BLiSS) trial.

Identifying behavioral pathways to smoking cessation in high-risk populations, such as low-income maternal smokers, could reduce tobacco disparities. The previous"BLiSS" multilevel intervention trial demonstrated efficacy of the BLiSS intervention in facilitating low-income maternal smokers' bioverified abstinence. This present study examined four putative pathways measured at 3-month end of treatment (Time 2) that could account for the observed intervention effect on smoking abstinence through 12 months (Time 2 - Time 3). Nutritionists in community clinics delivering safety net nutrition promotion programs across Philadelphia, Pennsylvania, USA, were trained by trial principal investigators to deliver a brief tobacco intervention informed by the American Academy of Pediatrics best practice guidelines ("Ask, Advise, Refer [AAR]"). After referral, 396 eligible participants were randomized to either a multimodal behavioral intervention (AAR + MBI) or a parallel attention control (AAR + control). Random effects regression analysis tested mediation. Elimination of children's tobacco smoke exposure (TSE) at Time 2 was the only significant mediator of longitudinal smoking abstinence through Time 3. AAR + MBI mothers were more likely to eliminate their children's TSE by Time 2 (OR = 2.11, 95%CI 1.30, 3.42), which was significantly associated with Time 3 abstinence (OR = 6.72, CI 2.28, 19.80). Modeling showed a significant total effect of AAR + MBI on abstinence (OR = 6.21, CI 1.86, 20.71), a direct effect of AAR + MBI on abstinence (OR = 4.80, CI 1.45, 15.94) and an indirect effect through TSE elimination (OR = 1.29, CI 1.06, 1.57). Integrating smoking cessation interventions with counseling prior to the quit attempt that is designed to facilitate adoption of smokefree home policies and efforts to eliminate children's TSE could enhance the likelihood of long-term abstinence in populations of smokers with elevated challenges quitting smoking.

Smoking in Children: A Habit or Fixation?

Even though most of the Indian population lives in a joint family system, where the focus of attention for the family is the child; still smoking in childhood and adolescence is very much prevalent. What is most disturbing about this fact, three-quarters of adolescents who smoke frequently carry on smoking as adults. It brings us to the point that, do we need to think of any other alternative, or do we need to shift our focus to some other direction? Should the focus be shifted from habit to years of psychological and personality development of the child?

Early childhood lower respiratory tract infection and premature adult death from respiratory disease in Great Britain: a national birth cohort study

Lower respiratory tract infections (LRTIs) in early childhood are known to influence lung development and lifelong lung health, but their link to premature adult death from respiratory disease is unclear. We aimed to estimate the association between early childhood LRTI and the risk and burden of premature adult mortality from respiratory disease. This longitudinal observational cohort study used data collected prospectively by the Medical Research Council National Survey of Health and Development in a nationally representative cohort recruited at birth in March, 1946, in England, Scotland, and Wales. We evaluated the association between LRTI during early childhood (age <2 years) and death from respiratory disease from age 26 through 73 years. Early childhood LRTI occurrence was reported by parents or guardians. Cause and date of death were obtained from the National Health Service Central Register. Hazard ratios (HRs) and population attributable risk associated with early childhood LRTI were estimated using competing risks Cox proportional hazards models, adjusted for childhood socioeconomic position, childhood home overcrowding, birthweight, sex, and smoking at age 20-25 years. We compared mortality within the cohort studied with national mortality patterns and estimated corresponding excess deaths occurring nationally during the study period. 5362 participants were enrolled in March, 1946, and 4032 (75%) continued participating in the study at age 20-25 years. 443 participants with incomplete data on early childhood (368 [9%] of 4032), smoking (57 [1%]), or mortality (18 [<1%]) were excluded. 3589 participants aged 26 years (1840 [51%] male and 1749 [49%] female) were included in the survival analyses from 1972 onwards. The maximum follow-up time was 47·9 years. Among 3589 participants, 913 (25%) who had an LRTI during early childhood were at greater risk of dying from respiratory disease by age 73 years than those with no LRTI during early childhood (HR 1·93, 95% CI 1·10-3·37; p=0·021), after adjustment for childhood socioeconomic position, childhood home overcrowding, birthweight, sex, and adult smoking. This finding corresponded to a population attributable risk of 20·4% (95% CI 3·8-29·8) and 179 188 (95% CI 33 806-261 519) excess deaths across England and Wales between 1972 and 2019. In this prospective, life-spanning, nationally representative cohort study, LRTI during early childhood was associated with almost a two times increased risk of premature adult death from respiratory disease, and accounted for one-fifth of these deaths.

Parental Smoking in Childhood as a Smoking Risk Factor Throughout Middle Age

Children of people who smoke have a well-documented higher risk of smoking initiation. However, little is known about the persistence of the association between parental smoking and children's own smoking as they age. This study uses data collected by the Panel Study of Income Dynamics collected between 1968 and 2017 and investigates the association between parental smoking and children's own smoking through middle age and how it may be modified by adult children's SES using regression models. The analysis was conducted between 2019 and 2021. The results show an increased risk of smoking among adult children of parents who smoked. Their odds were elevated in young adulthood (OR=1.55, 95% CI=1.11, 2.14), established adulthood (OR=1.53, 95% CI=1.08, 2.15), and middle age (OR=1.63, 95% CI=1.04, 2.55). Interaction analysis shows that this statistically significant relationship is limited to high-school graduates only. Among people who smoked in the past or who currently smoke, children of people who smoked had longer average smoking duration. Interaction analysis shows that this risk is limited to high-school graduates only. The adult children of people who smoked and have less than a high-school education, some college, and college graduates did not have a statistically significantly increased risk of smoking or longer smoking duration. The findings highlight the durability of early life influences, especially for people with low SES.

The Association Between Inflammatory Bowel Disease and Exposure to Tobacco Smoking: A Case-Control Study in Qatar.

This research investigated the association between childhood and adulthood tobacco smoking exposure with ulcerative colitis (UC) and Crohn's disease (CD) in Qatar. In this case-control study, CD and UC cases were matched to controls of the same age and sex. The associations between UC and CD and childhood passive smoking and adulthood active smoking were assessed using conditional multivariable logistic regression. A total of 89 CD cases, median age of 37 years (IQR 29-47), and 362 UC cases, median age of 35 years (IQR 28-44), and equal numbers of controls were included. After multivariable logistic regression, CD was associated with higher odds of being a current smoker (OR 2.51, 95% CI 0.85-7.37, p=0.095), with weak evidence against the null hypothesis. This association was more pronounced in women, where CD was associated with both adulthood current smoking (OR 42.71, 95% CI, 1.17-1559.57, p=0.041), and childhood smoking exposure (OR 8.23, 95% CI, 1.36-49.66, p=0.021). In males, no associations were observed between CD and the smoking exposures. No associations were observed between UC and both smoking variables. In Qatar, adulthood tobacco smoking appears to increase the odds of CD. Further, our findings suggest that both childhood and adulthood cigarette smoke exposure may possibly have a detrimental effect on the odds of CD in females but not in males, although further research is needed.

A link between solar activity and smoke with hemoblastosis in children

The study of the role of environmental factors in the occurrence of human neoplasms is an important task of medical ecology. An indicator of carcinogenic environmental impacts is childhood tumors due to the predominantly prenatal genesis of tumors at this age. In the structure of childhood oncological morbidity, hemoblastosis predominate. The link between the incidence of childhood leukemia and exposure to ultraviolet radiation, the protective role of sun exposure in relation to the risk of non-Hodgkin’s lymphomas (NHL) and the absence of such in Hodgkin’s lymphoma in children have been established. There is evidence of the connection between childhood hemoblastosis and smoke of various origins. The aim of the study was to evaluate the link between solar activity and smoke with hemoblastosis in the Russian children. We used official data on the incidence of childhood hemoblastosis in Russia in 1997-2020 and data on solar activity from the site of the Royal Observatory of Belgium. The generated dynamic series was subjected to correlation and regression analysis in 11 consecutive iterations with a time delay (lag) from 0 to 10 years in relation to the year of registration of neoplasms. An increase in the incidence of leukemia and a decrease in the incidence of Hodgkin’s lymphoma in the children’s population of Russia have been established. The incidence of NHL in children did not reveal a significant trend. A general pattern was revealed in the form of the connection between childhood leukemia and lymphomas and solar activity, most pronounced in 1997-2008. The increase in the childhood leukemia incidence, taking into account the literature data of the role of exhaust gases in its genesis, can be associated with a threefold increase in the number of cars in Russia during the study period. The reasons for the decrease in the incidence of Hodgkin’s lymphoma require further study. To reduce the risk of hemoblastosis in children, it is advisable to introduce food products into the diet to stimulate autophagy, and transfer factor.

Prenatal and Childhood Smoke Exposure Associations with Cognition, Language, and Attention-Deficit/Hyperactivity Disorder

To assess the relationships of prenatal and childhood smoke exposure with specific neurodevelopmental and behavioral problems during early childhood. A subsample (n=386) of mother-child dyads from the Newborn Epigenetic Study (NEST) prebirth cohort participated in the study. Cotinine concentrations were used to objectively measure prenatal and childhood smoke exposure when youth were aged 3-13years. Multivariable regression models were used to estimate associations of prenatal and childhood cotinine concentrations with performance on the National Institutes of Health (NIH) Toolbox and attention-deficit/hyperactivity disorder and behavioral symptoms, measured using the Behavior Assessment System for Children, 2nd edition (BASC-2). After adjusting for confounders, childhood cotinine concentrations were associated with poorer cognitive performance on tasks measuring cognitive flexibility (B=-1.29; P=.03), episodic memory (B=-0.97; P=.02), receptive language development (B=-0.58; P=.01), and inhibitory control and attention (B=-1.59; P=.006). Although childhood cotinine concentration was associated with higher levels of attention problems (B=0.83; P=.004) on the BASC-2, after adjustment for confounders, the association is nonsignificant. Although associations for maternal cotinine concentrations were null, an interaction was detected between prenatal and childhood cotinine concentrations on the NIH Toolbox Picture Vocabulary Task (P=.02). Our findings suggest that childhood tobacco smoke exposure may lead to poorer attention regulation and language acquisition, complex visual processing ability, and attention problems.

Factors Associated With Persistence of Severe Asthma From Late Adolescence to Early Adulthood

To determine risk factors in childhood that predict severe persistent asthma in late adolescence and early adulthood.Patients aged 5 to 12 years with mild to moderate asthma and a positive methacholine challenge enrolled in the Childhood Asthma Management Program (CAMP) trial.The CAMP participants above who had data available from late adolescence to early adulthood were included. The first study visit at age 18 years was used to determine asthma activity in late adolescence, whereas the first study at age 22 years was used to determine asthma activity in early adulthood. The American Thoracic Society definition of severe asthma was used for patients on high dose inhaled corticosteroids and the National Asthma Education and Prevention Program Expert Panel Report (NAEPP EPR) 3 definition of severe asthma was used for those not receiving high dose inhaled corticosteroids. Additional criteria for intermittent and persistent asthma were included. The following factors were analyzed: secondhand smoke exposure, maternal smoking during pregnancy, body mass index percentile, hay fever, eczema, food allergy, parental asthma being sensitized and exposed to any perennial aeroallergen, bronchial hyperreactivity, prebronchodilator FEV1/FVC ratio, post bronchodilator FEV1/FVC ratio, bronchial hyperresponsiveness to methacholine challenge, log10 of serum total IgE and log10 of serum absolute eosinophil count. Characteristics were compared from baseline to late adolescence and from baseline to early adulthood.Six hundred eighty-two CAMP participants were included. Of these participants, severe asthma was present in 81 (12%) participants in late adolescence and 131 (19%) participants in early adulthood. Half of the patients with severe asthma in late adolescence continued to have severe asthma into early adulthood. About 18% of patients improved severity, 61% did not change, and 21% of patients worsened in severity from late adolescence to early adulthood. The postbronchodilator percent predicted FEV1 and pre and post bronchodilator FEV1/FVC ratio significantly decreased from childhood to late adolescence and from late adolescence to early adulthood (P < .0001), whereas prebronchodilator FEV1 values increased from childhood to late adolescence (P < .0001) and stabilized in early adulthood (P = .040). Bronchodilator reversibility and bronchial hyperresponsiveness each decreased from childhood to late adolescence (P < .0001), whereas bronchial hyperresponsiveness also significantly decreased from childhood to early adulthood (P = .0003). Patients with persistent and severe asthma had higher serum IgE in late adolescence and were more likely to have a positive aeroallergen skin test, along with sensitization and exposure to perennial allergens in childhood. Significant factors in early childhood that were associated with persistence of severe asthma from late adolescence to early adulthood included a younger age, male sex, no reported hay fever, a low prebronchodilator FEV1/FVC ratio, a low postbronchodilator FEV1/FVC ratio, and a physician diagnosis of moderate asthma during the screening period. Notably, for every 5% decrease in post bronchodilator FEV1/FVC ratio in childhood, the odds of severe asthma persistence increased by 2.36-fold (P < .0001) as well as maternal smoking during pregnancy increased odds of severe asthma persistence by 3.17-fold (P = .020). There was a strong association between a reduced-growth lung function trajectory and severe asthma persistence.Lower FEV1/FVC ratio in childhood and maternal smoking during pregnancy were the strongest predictors for severe asthma between late adolescence and early adulthood.Understanding early factors for persistence of asthma into adulthood can help develop targeted primary prevention measures such as reduction of smoking during pregnancy as well as early intervention measures with therapies to preserve lung function in childhood.URL: www.pediatrics.org/cgi/doi/10.1542/peds.10.1164/rccm.202010-3763OC

Risk factors for natural menopause before the age of 45: evidence from two British population-based birth cohort studies

BackgroundMenopause that occurs before the age of 45 and is not medically induced (referred to here as ‘early natural menopause’) affects around one in 10 women and has serious health consequences. These consequences include increased risk of all-cause mortality, cardiovascular disease, osteoporosis, and type 2 diabetes.MethodsWe investigate risk factors for the onset of natural menopause before the age of 45 in two population-based prospective cohort studies in Britain: the 1958 cohort following 8959 women and the 1970 cohort following 8655 women. These studies follow women from birth to adulthood, and we use harmonized data on birth and early life characteristics, reproductive health, health behaviour, and socioeconomic characteristics for 6805 women who were pre-menopausal, peri-menopausal or had undergone natural menopause. Of these 6805 women, 3614 participated in the 1958 cohort (of which 368 had early menopause) and 3191 participated in the 1970 cohort (of which 206 had early menopause). Taking a life course approach, we focus on three distinct life stages - birth/early life, childhood, and early adulthood - to understand when risk factors are most harmful. Respecting the temporal sequence of exposures, we use a series of multivariable logistic regression models to estimate associations between early menopause and each potential risk factor adjusted for confounders.ResultsWe find that early menopause is influenced by circumstances at birth. Women born in lower social class families, whose mother smoked during the pregnancy or who were breastfed 1 month or less were more likely to undergo early menopause. Early menopause is also associated with poorer cognitive ability and smoking in childhood. Adult health behaviour also matters. Smoking is positively correlated with early menopause, while regular exercise and moderate frequency of alcohol drinking in women’s early thirties are associated with reduced risk of early menopause. The occurrence of gynaecological problems by women’s early thirties is also linked to early menopause.ConclusionsWe demonstrate that characteristics at different periods of life are associated with early menopause. Some of these associations relate to modifiable behaviours and thus the risks of early menopause and the adverse health outcomes associated with it may be preventable.

Maternal Adverse and Protective Childhood Experiences and Prenatal Smoking

Prenatal smoking is associated with adverse pregnancy and birth outcomes as well as health problems in early childhood. Recent research determined that maternal adverse childhood experiences (ACEs) increase the odds of smoking during pregnancy. We consider the role of protective and compensatory childhood experiences (PACEs) in an effort to examine the extent to which positive childhood experiences are protective factors for maternal smoking behaviors. Between 2015-2018, 309 pregnant women in Oklahoma recruited from high-risk prenatal clinics, childbirth education classes, and social media were surveyed about their childhood experiences and smoking behaviors during pregnancy. Ordinal regression analysis was used to examine the association between ACEs, PACEs, and prenatal smoking frequency. Similar to prior studies, we found women with more ACEs reported smoking more frequently during pregnancy. Women with more PACEs reported significantly less frequent prenatal smoking. With both ACEs and PACEs in the model, however, ACEs was no longer a significant predictor of maternal prenatal smoking. Our findings suggest that protective and compensatory childhood experiences may be more salient for prenatal smoking behaviors than adverse childhood experiences. Identifying protective factors for pregnancy health risk behaviors such as smoking can offer a target for intervention and prevention.

Dramatic changes in multiple sclerosis incidence in Iran may be related to the “Will Rogers phenomenon”

In recent years, studies have shown that multiple sclerosis (MS) incidence has greatly increased in different geographical areas of Iran (Pakdel et al., 2020; Hosseinzadeh et al., 2021). The increases in MS incidence in Iran are usually attributed to obesity and overweight childhood, cigarette and waterpipe smoking, vitamin D deficiency, urbanization, industrialization, and air pollution (Amiri, 2021; Hosseinzadeh et al., 2019; Asmarian et al., 2021). However, one of the most important factors that may be related to the increase of MS incidence in Iran and has been neglected is the “Will Rogers phenomenon

Exposure to parental smoking and cardiac structure and function in adulthood: the Cardiovascular Risk in Young Finns Study.

The relationship between childhood tobacco smoke exposure and cardiac structure and function in midlife is unclear. We investigated the association between parental smoking with cardiac structure and function in adulthood. 1250 participants (56.5% female) from the Cardiovascular Risk in Young Finns Study who had data on parental smoking and/or serum cotinine, a biomarker of exposure to tobacco smoke, at baseline 1980 (age 3-18 years) and echocardiography performed in 2011. Parental smoking hygiene (i.e., smoking in the vicinity of children) was categorized by parental smoking and serum cotinine levels in offspring. Dimensions of the left ventricle, diastolic and systolic function, and cardiac remodeling were used as outcomes. Analyses were adjusted for sex, age, and covariates (blood pressure (BP), serum lipids, body mass index, socioeconomic status, smoking (only in adulthood)) in childhood and adulthood. Parental smoking was not associated with systolic or diastolic function in adulthood. Participants exposed to parental smoking (odds ratio (OR) 1.90, 95%CI 1.23-2.92), hygienic parental smoking (OR 1.74, 95%CI 1.12-2.71), and non-hygienic parental smoking (OR 1.88, 95%CI 1.02-3.45) had higher odds of concentric remodeling (relative wall thickness >85th sex-specific percentile without left ventricular hypertrophy). These associations were attenuated after adjustment for child and adult covariates in the non-hygienic parental smoking group. Exposure to parental smoking in childhood was associated with a higher likelihood of concentric remodeling and thicker left ventricular and interventricular septal walls in midlife, which was not improved by parents who smoked hygienically. Parental smoking was not related to systolic or diastolic function in this relatively young population.
