Social and Emotional Adjustment Following Early Pregnancy in Young Australian Women: A Comparison of Those Who Terminate,Miscarry, or Complete Pregnancy

PurposeTo compare social and emotional adjustment including educational attainment and substance use in women who had a child, pregnancy termination, or miscarriage by young adulthood.MethodsData were from a population-based longitudinal study of the health and well-being of 1,943 young Australians (Victorian Adolescent Health Cohort Study) followed from 15 to 24 years of age. The sample was restricted to female participants and based on pregnancies reported by age 24 years. Analyses were adjusted for early teenage depressive symptoms, cigarette smoking, alcohol use, cannabis use, and parent socioeconomic context.ResultsA total of 208 pregnancies (in 170 women) were reported from a sample of 824 young women by 24 years of age. Compared with those who had never been pregnant, those who had a child had lower tertiary education completion and a higher risk of nicotine dependence; those who terminated a pregnancy were more commonly single and had a higher risk of smoking and alcohol use as well as nicotine and alcohol dependence; and those who had a miscarriage had a higher risk of depressive symptomatology and binge drinking as well as nicotine and cannabis dependence.ConclusionsYoung women who have been pregnant by their mid-twenties report a range of difficulties in social and emotional adjustment that vary across the different pregnancy outcomes. Broad-based psychosocial health care is essential not only for young women whose pregnancies proceed to live birth, but also for those whose pregnancies end with miscarriage or induced abortion.     

Sex and age differences in lifestyle risk: implications for health promotion programming

We analyzed data from the 1982 Texas Behavioral Risk Factor Survey by sex and age to suggest strategies for the design and implementation of risk reduction programs. Men were more likely than women to report heavy drinking (76 percent versus 62 percent), drinking and driving (11 percent versus 3 percent), smoking (34 percent versus 27 percent), being overweight (42 percent versus 32 percent), and not using seat belts (63 percent versus 58 percent). Women were slightly more likely to report insufficient physical activity (64 percent versus 60 percent). A larger percentage of women than men reported using eating to cope with stress (31 percent versus 15 percent), while smoking (26 percent versus 22 percent), alcohol use (8 percent versus 3 percent), and exercise (21 percent versus 14 percent) were coping mechanisms reported by a greater proportion of men than women. These differences in risk behaviors by sex and age suggested that worksite programs addressing weight control and smoking for men and women and alcohol use and driving for men, along with community-based programs emphasizing fitness and hypertension control for older adults, would be most effective.     

Alcohol dependence and depression among heavy drinkers in Canada

This article describes the prevalence of heavy drinking among the Canadian population and the prevalence of alcohol dependence among heavy drinkers aged 18 or older. It also examines the association of depression to alcohol dependence among the latter group and the correlates of depression and alcohol dependence comorbidity. The data are from a national representative sample of the Canadian population in 2000/01. One in five current drinkers aged 18 or older was classified as a regular heavy drinker. This constituted a significant increase of approximately 2% in the prevalence of heavy drinking from 1996/97 to 2000/01 in Canada (p<0.001). Although men were more likely to be regular heavy drinkers (29.0%) than women (11.1%), male and female heavy drinkers were about equally as likely to be classified as alcohol dependent (11.6% and 11.1%, respectively). While the prevalence of alcohol dependence among men has remained stable, it has decreased by almost 4% among women (p<0.05). Among persons who have experienced a depressive episode in the year prior to their 2000/01 interview, the prevalence of alcohol dependence was estimated at 32.3% while it was 9.5% for persons without depression. When several indicators believed to be risk factors for alcohol dependence including personal characteristics, psychosocial factors, lifestyle behaviours and physical health were included in the logistic regression models, the marked difference in alcohol dependence among depressed and non-depressed heavy drinkers remained. The former had 3.6 times the odds of being classified as alcohol dependent compared to the latter (CI=2.9, 4.3). When the same personal, psychosocial, lifestyle and physical health measures were used to explain comorbidity of depression and alcohol dependence, perceived stress was the only factor that was consistently associated with comorbidity among both men and women.

Smoking initiation and nicotine dependence symptoms in Ukraine: findings from the Ukraine World Mental Health survey

OBJECTIVES: Cigarette smoking is a major cause of morbidity and mortality in former Soviet countries. This study examined the personal, familial and psychiatric risk factors for smoking initiation and development of nicotine dependence symptoms in Ukraine. STUDY DESIGN: Cross-sectional survey. METHODS: Smoking history and dependence symptoms were ascertained from N=1711 adults in Ukraine as part of a national mental health survey conducted in 2002. Separate analyses were conducted for men and women. RESULTS: The prevalence of lifetime regular smoking was 80.5% in men and 18.7% in women, with median ages at initiation among smokers of 17 and 18, respectively. Furthermore, 61.2% of men and 11.9% of women were current smokers; among the subgroup of lifetime smokers, 75.9% of men and 63.1% of women currently smoked. The youngest female cohort (born 1965-1984) was 26 times more likely to start smoking than the oldest. Smoking initiation was also linked to childhood externalizing behaviors and antecedent use of alcohol in both genders, as well as marital status and personal alcohol abuse in men, and childhood urbanicity and birth cohort in women. Dependence symptoms developed in 61.7% of male and 47.1% of female smokers. The rate increased sharply in the first four years after smoking initiation. Dependence symptoms were related to birth cohort and alcohol abuse in both genders, as well as growing up in a suburb or town and childhood externalizing behaviors in men, and parental antisocial behavior in women. CONCLUSIONS: Increased smoking in young women heralds a rising epidemic in Ukraine and underscores the need for primary prevention programs, especially in urban areas. Our findings support the importance of childhood and alcohol-related risk factors, especially in women, while pre-existing depression and anxiety disorders were only weakly associated with starting to smoke or developing dependence symptoms.     

Occurrence of chronic obstructive pulmonary disease among Canadians and sex-related risk factors

The etiology of chronic obstructive pulmonary disease (COPD) has not been fully understood. This analysis assessed the prevalence of COPD and its risk factors among Canadian men and women. The analysis was based on the data from 7210 subjects aged 35 to 64 years who participated in the first cycle of National Population Health Survey in 1994-1995. COPD was considered present if an affirmative response was given to the question: "Do you have chronic bronchitis or emphysema diagnosed by a health professional?" In order to take the complex survey design into account, analytic weights incorporating a design effect were used in all statistical analyses. The prevalence of COPD was 2.1% in nonsmokers, 2.7% in ex-smokers, and 8.2% in smokers in women. In men, the corresponding prevalence was 0.8%, 2.9%, and 3.5%, respectively. The adjusted odds ratio for current smoking men and women who started smoking before age of 18 years was 3.0 and 5.9 compared with their nonsmoking counterparts. Overweight women demonstrated a 2.4-fold increase in the prevalence of COPD compared with women with normal weight. Men from low-income families had an odds ratio of 3.7 compared with those from high-income families. A history of allergy was significantly related to COPD in both men and women. COPD was common among Canadian women. Early initiation of smoking and being overweight had stronger relationships to the prevalence of COPD in women than in men. On the contrary, household income was more strongly related to COPD for men than for women.     

The Association of Healthy Lifestyle Behaviors with Overweight and Obesity among Older Adults from 21 Countries

This study aimed to analyze the association of healthy lifestyle behaviors with overweight and obesity among Europeans aged 65+ years. Data were from the 2014 European Social Survey, analyzing 21 countries. Five lifestyle behaviors (physical activity, fruit and vegetable consumption, sleep quality, drinking alcohol, and smoking) were analyzed. Binary logistic regressions were performed. A total of 8938 participants (4099 men) 65 years and older, mean age—73.6 (SD: 6.6) presented prevalence of overweight of 42.3% (95% CI: 41.3 to 43.3) and obesity of 20.9% (95% CI: 20.1 to 21.8). Adopting five healthy behaviors was associated with lower odds of obesity (OR = 0.50, 95% CI: 0.39 to 0.63), but not overweight (OR: 0.93; 95% CI: 0.79 to 1.10). Physical activity (≥5 days/week) was the most protective behavior, reducing by 42% the odds of obesity. Sex moderated the association of fruits and vegetables consumption, alcohol use, and smoking with obesity. Strategies aiming to reduce obesity levels in older adults should focus on the promotion of multiple lifestyle health behaviors, particularly physical activity in order to decrease vulnerability risk in old age.     

The mortality risk of smoking and obesity combined

BACKGROUND: Both smoking and obesity have been linked to increased mortality, but evaluating the joint effect has been limited. This nationwide, prospective mortality study of U.S. radiologic technologists was designed to evaluate the combined mortality risks of obesity and smoking. METHODS: Mortality risk was investigated in 64,120 women and 18,760 men who completed a baseline questionnaire (1983 to 1989). Body mass index (BMI) (weight adjusted for height, or kilograms divided by meters squared) was calculated from self-reported weight and height at baseline, with five categories: less than 18.5 (underweight), 18.5 to 24.9 (normal), 25.0 to 29.9 (overweight), 30.0 to 34.9 (moderately obese), and 35.0 and higher (very obese). Participants were followed from the questionnaire until the date of death or through 2002, whichever occurred first. The combined association among BMI and smoking and all-cause, cancer, and circulatory disease mortality by gender and attained age (less than 65 years, 65 years and older) was examined using Cox proportional hazards regression analyses (conducted in 2005). Person-years at risk averaged 16 years (women aged less than 65), 6 years (women aged 65 and older), 15 years (men aged less than 65), and 7 years (men aged 65 and older), totaling 1.35 million person-years. RESULTS: In all gender/age groups, both obesity and smoking, particularly current smoking, contributed substantially to all-cause mortality, with 3.5- to 5-fold risks for very obese, current smokers compared to normal weight, never smokers. Current smoking was the predominant risk factor for cancer mortality. Combining obesity with current smoking increased circulatory disease mortality by 6- to 11-fold for people aged less than 65 years, compared to normal weight, never smokers. Obese former smokers (less than 65 years) had notably lower risks. CONCLUSIONS: Obese smokers (aged less than 65 years) had strikingly high mortality risks, particularly from circulatory disease mortality.     

Epidemiological study of preferable life style for psychological health promotion

OBJECTIVE: We sought to examine relationships of lifestyle factors, including diet, physical activity, sleep, alcohol consumption and smoking, with perceived stress and depressive symptoms. METHODS: Between 2001 and 2002, 7,947 men and women (mean 52.4 years) took part in examinations at the Osaka Medical Center for Health Science and Promotion. Lifestyle factors were determined by structured interview or by self-administered questionnaire. Associations of life style factors with perceived stress and depressive symptoms were tested by stepwise logistic regression analyses. RESULTS: Higher proportions of persons with depressive symptoms tended to be associated with higher proportions of persons with perceived stress. Among both men and women, low physical activity, lack of regular physical exercise, short sleeping time, to skip breakfast frequently, and having dinner within a couple of hours before going to bed were associated with both perceived stress and depressive symptoms. Men reporting between-meal or midnight snacks and having eating until they were full had higher odds ratios for perceived stress, while men conducting regular physical exercise and consuming 3 or more dishes of vegetables per day had lower odds ratios for depressive symptoms. For women, high odds ratios for depressive symptoms and perceived stress were observed among those who tended to have salty foods (or frequent use of soy sauce) and a lower odds ratio for perceived stress was noted among persons who had soy products every day. CONCLUSION: Lifestyle facets such as skipping breakfast, low physical activity, and short sleeping time, appear to be associated with psychological health status of Japanese men and women.     

Effect of major lifestyle risk factors,independent and jointly,on life expectancy with and without cardiovascular disease: results from the Consortium on Health and Ageing Network of Cohorts in Europe and the United States (CHANCES)

Seldom have studies taken account of changes in lifestyle habits in the elderly, or investigated their impact on disease-free life expectancy (LE) and LE with cardiovascular disease (CVD). Using data on subjects aged 50+ years from three European cohorts (RCPH, ESTHER and Tromsø), we used multi-state Markov models to calculate the independent and joint effects of smoking, physical activity, obesity and alcohol consumption on LE with and without CVD. Men and women aged 50 years who have a favourable lifestyle (overweight but not obese, light/moderate drinker, non-smoker and participates in vigorous physical activity) lived between 7.4 (in Tromsø men) and 15.7 (in ESTHER women) years longer than those with an unfavourable lifestyle (overweight but not obese, light/moderate drinker, smoker and does not participate in physical activity). The greater part of the extra life years was in terms of “disease-free” years, though a healthy lifestyle was also associated with extra years lived after a CVD event. There are sizeable benefits to LE without CVD and also for survival after CVD onset when people favour a lifestyle characterized by salutary behaviours. Remaining a non-smoker yielded the greatest extra years in overall LE, when compared to the effects of routinely taking physical activity, being overweight but not obese, and drinking in moderation. The majority of the overall LE benefit is in disease free years. Therefore, it is important for policy makers and the public to know that prevention through maintaining a favourable lifestyle is “never too late”.     

Living arrangements, heavy drinking and alcohol dependence

AIMS: To assess the variation in heavy drinking and alcohol dependence by living arrangements, and the contribution of social and behavioural factors to this variation. DESIGN: The Health 2000 survey is a nationally representative cross-sectional survey conducted in Finland in 2000-2001 (N = 4589 in the age-range of 30-54 years, response rate 81%). MEASUREMENTS: Living arrangements; married, cohabiting, living with other(s) than a partner, and living alone. Consumption of beer, wine and spirits in the past month was converted into grams of alcohol/week, and heavy drinking was classified as > or =280 (men) and > or =140 (women) grams/week. Twelve-month prevalence of alcohol dependence was diagnosed by a mental health interview (CIDI). FINDINGS: As compared to the married, cohabiting and living alone associated with heavy drinking (age-adjusted OR; 95% CI: 1.71;1.17-2.49 and OR 2.15;1.55-3.00 in men; OR 1.54;0.96-2.46 and OR 1.67;1.07-2.63 in women) and alcohol dependence (OR 2.29;1.44-3.64 and OR 3.66;2.39-5.59 in men; OR 2.56;1.10-5.94 and OR 4.43;2.03-9.64 in women). Living with other(s) than a partner associated with heavy drinking. Those who cohabited without children or lived alone had the highest odds for alcohol dependence. Among both genders, adjusting for main activity and financial difficulties attenuated the odds for heavy drinking and alcohol dependence by approximately 5-30% each, and additionally among women adjusting for urbanisation attenuated the odds for heavy drinking by approximately 15-45%. CONCLUSIONS: Cohabiting and living alone are associated with heavy drinking and alcohol dependence. Unemployment, financial difficulties and low social support, and among women also living in an urban area, seem to contribute to the excess risk.     

Non-fatal occupational injury among active and passive smokers in small- and medium-scale manufacturing enterprises in Japan

Active smoking is a risk factor for occupational injury, whereas its association with passive smoking is unknown. To evaluate the contribution of active and passive smoking to non-fatal occupational injury in manufacturing sectors, 2302 randomly selected workers aged 16-83 years working in 244 small- and medium-scale enterprises in Yashio city, Japan, were surveyed by means of a self-administered questionnaire. Smoking history, exposure to passive smoking, and occupational injury were evaluated by self-report. Exposure levels to passive smoking were assessed separately at work and at home as never, occasional, or regular exposure. Overall, 61.4% of men and 22.3% of women were current smokers. Among never smokers, 62.2% of men and 68.6% of women reported exposure to passive smoking either at work or home. Prevalence of occupational injuries was 36.2% for never, 43.3% for former, and 41.2% for current smokers among men and 19.7% for never, 22.2% for former, and 25.2% for current smokers among women. Among never smoking men, odds ratios (ORs) of occupational injury were 2.11 when regularly exposed to passive smoking at work or at home (p=0.025), 2.27 at work (p=0.015), and 3.08 at home (p=0.106), in comparison to never smoking men who were never exposed to passive smoking either at work or at home (referent group). These associations were attenuated to be non-significant, after controlling for potential confounders. Never smoking men with occasional exposure to passive smoking were not significant ORs (1.11-1.19). In contrast, current and former smoking men had significant increases in adjusted ORs (1.57-2.00). In women exposed to smoking there was a non-significant increase in occupational injury. The present study indicates an expected increase in the risk of, occupational injury for current and former smoking men and suggests that exposure to passive smoking is a possible risk factor for never smoking men.     

Clinical correlates of cigarette smoking and nicotine dependence in alcohol-dependent men and women. The Collaborative Study Group on the Genetics of Alcoholism

This paper examines the clinical characteristics associated with tobacco use and nicotine dependence in a large sample of alcohol-dependent subjects. The goal was to determine if the characteristics of the alcohol use history were associated with the smoking status, even after controlling for additional characteristics, such as the antisocial personality disorder, other drug dependence and gender. As part of the Collaborative Study on the Genetics of Alcoholism, a semi-structured interview, including a detailed history of alcohol and tobacco use, was administered to 1005 alcohol-dependent men and women, made up of 658 (65.5%) current smokers, 167 (16.6%) former smokers, and 180 (17.9%) non-smokers. Among former smokers, 50.3%, and among current smokers, 72.8% had ever been nicotine-dependent (DSM-III-R). Current smokers and nicotine-dependent subjects had a greater severity of alcohol dependence, even as evaluated through logistic regression analyses in which gender and associated diagnoses were considered. The data also enabled us to study the relationships among depression, nicotine dependence, and alcohol dependence, with most of the correlation occurring for substance-induced, not independent, mood disorders.     

Social gradients in binge drinking and abstaining: trends in a cohort of British adults

OBJECTIVE: To investigate (1) social gradients in non-drinking and binge drinking, and (2) changes in social gradients in drinking with increasing age. METHODS: British men and women born during the same week in March 1958 were prospectively followed up to adulthood. The frequency and amount of alcohol use were recorded at age 23, 33 and 42 years. Abstainers "never" drank, binge drinkers consumed >or=10 units (men) and >or=7 units (women) per occasion. Educational qualifications and occupation were reported at age 23 and 33 years. Logistic and repeated-measures models were used to investigate associations between social position and drinking status at single and multiple ages in adulthood. RESULTS: Less educated men and women had greater odds of being non-drinkers at each age in adulthood, with similar gradients at ages 23-42 years. At 23 years of age, men without qualifications had 2.94 times greater odds of non-drinking than men with higher qualifications. Less educated men had greater odds of binge drinking, and gradients did not change at ages 23-42 years. At age 23 years, less educated women had lower odds of binge drinking (odds ratio (OR) 0.67 for women with no qualifications) than women with higher qualifications. By age 42 years, the gradient reversed, and less educated women had higher odds of binge drinking (OR 2.68). CONCLUSIONS: Stable gradients in non-drinking and trends in gradients in binge drinking may reinforce alcohol-related health inequalities over time.

Active and passive smoking and depression among Japanese workers

OBJECTIVE: To assess the relation of passive and active smoking to depressive symptoms in 1839 men and 931 women working in a suburb of Tokyo in 2002. METHOD: Self-reported smoking history and exposure to passive smoking (no, occasional, or regular) at work and at home. Depressive symptoms according to the Center for Epidemiologic Studies Depression Scale, with a cut-off point of 16. RESULTS: Compared to never smokers unexposed to passive smoking, never smokers reporting regular and occasional exposure to passive smoking at work had increased depressive symptoms. The adjusted odds ratios (aORs) were 1.92 (95% confidence interval (CI) 1.14, 3.23) for regular exposure and 1.63 (95% CI 1.08, 2.47) for occasional exposure. Current smokers had significantly increased depressive symptoms (aOR ranging from 2.25 to 2.38) but former smokers had only marginal increases of depressive symptoms (aOR ranging from 1.43 to 1.55). Gender did not modify the effects of active/passive smoking on depressive symptoms. CONCLUSION: Passive smoking at work and current smoking appear associated with higher levels of depressive symptoms.     

Does maternal smoking during pregnancy have a direct effect on future offspring obesity? Evidence from a prospective birth cohort study

The authors used a population-based birth cohort of 3,253 children (52% males) born in Brisbane, Australia, between 1981 and 1984 to prospectively examine whether maternal smoking during pregnancy was associated with offspring overweight and obesity. The authors compared mean body mass indexes (weight (kg)/height (m)2) and levels of overweight and obesity at age 14 years among offspring by patterns of maternal smoking (never smoked, smoked before and/or after pregnancy but not during pregnancy, or smoked during pregnancy). Adolescent body mass index and prevalences of overweight and obesity were greater in offspring whose mothers had smoked during pregnancy than in those whose mothers had never smoked. Body mass index and levels of overweight and obesity among adolescent offspring whose mothers stopped smoking during pregnancy but smoked at other times in the child's life were similar to those among offspring whose mothers had never smoked. These results were independent of a range of potentially confounding factors and suggest a direct effect of maternal smoking during pregnancy on adolescent overweight and obesity. They provide yet another incentive for pregnant women to be persuaded not to smoke and for young women to be encouraged to never take up smoking.     

Alcohol and hepatocellular carcinoma: the effect of lifetime intake and hepatitis virus infections in men and women

The authors investigated the dose-effect relation between alcohol drinking and hepatocellular carcinoma (HCC) in men and women separately, also considering hepatitis B and hepatitis C virus infections. They enrolled 464 subjects (380 men) with a first diagnosis of HCC as cases and 824 subjects (686 men) unaffected by hepatic diseases as controls; all were hospitalized in Brescia, northern Italy, in 1995-2000. Spline regression models showed a steady linear increase in the odds ratio of HCC for increasing alcohol intake, for values of >60 g of ethanol per day, with no substantial differences between men and women. Duration of drinking and age at start had no effect on the odds ratio when alcohol intake was considered. Former drinkers who had stopped 1-10 years previously had a higher risk of HCC than current drinkers did. The effect of alcohol drinking was evident even in the absence of hepatitis B or hepatitis C virus infection. In addition, a synergism between alcohol drinking and either infection was found, with approximately a twofold increase in the odds ratio for each hepatitis virus infection for drinkers of >60 g per day.     

The metabolic syndrome and associated lifestyle factors among South Korean adults

INTRODUCTION: The importance of managing the metabolic syndrome has been emphasized in the prevention of cardiovascular disease. Although South Koreans have a low prevalence of obesity, little information is available about the prevalence of the metabolic syndrome and its associated risk factors. METHODS: Data was obtained from individuals aged 20-79 years from the Korean National Health and Nutrition Examination Survey 1998, a cross-sectional health survey of a nationally representative sample of non-institutionalized civilian South Koreans. The prevalence of the metabolic syndrome, as defined by the Third Report of the National Cholesterol Education Program Adult Treatment Panel (NCEP ATP III), was determined, and lifestyle factors associated with predisposition to the metabolic syndrome were analysed. RESULTS: Among South Korean adults, the age-adjusted prevalence of the metabolic syndrome was 14.2% for men and 17.7% for women, whereas the age-adjusted prevalence of obesity (body mass index (BMI) >or=30 kg/m(2)) was 1.7% and 3.0% for men and women, respectively. Age, unemployment, higher BMI, and current smoking were associated factors for the metabolic syndrome regardless of gender. Moderate exercise (2-3 sessions/week) in men and light alcohol drinking (<15 g/day) in women decreased the odds of the metabolic syndrome. CONCLUSIONS: Metabolic syndrome is present in more than 15% of South Koreans despite a low prevalence of obesity. Higher BMI and current smoking were identified as independent modifiable risk factors of the metabolic syndrome. Weight control and smoking cessation may therefore decrease the prevalence of the metabolic syndrome in South Korean adults.     

Physical activity, cardiorespiratory fitness and body mass index as predictors of substantial weight gain and obesity: the Canadian physical activity longitudinal study

BACKGROUND: Obesity is a growing health issue in Canada and the identification of the determinants of obesity is important for the development of prevention strategies. The purpose of this investigation was to determine the relationships between physical activity, cardiorespiratory fitness, body mass index (BMI), and the development of future obesity. METHODS: The sample included 459 adults (18+ y; 223 men, 236 women) from the Canadian Physical Activity Longitudinal Study (PALS; 2002-04). Data on physical activity, smoking, alcohol consumption, BMI, and cardiorespiratory fitness (VO2max) were collected in 1981 and 1988. The mean BMI, physical activity, and VO2max were calculated across the 1981 and 1988 measures. Self-reported height and weight were collected in the 2002-04 survey, and participants were classified as overweight (BMI 25 to 29.9 kg/m2) or obese (BMI 230 kg/m2). Logistic regression was used to predict overweight, obesity or substantial weight gain (10 kg or more) in 2002-04, controlling for age, sex, smoking and alcohol use. RESULTS: Higher VO2max in 1981-88 was associated with lower odds of obesity in 2002-04 (OR = 0.87; 95% Cl: 0.76-0.99, p < 0.05), and higher BMI in 1981-88 was associated with higher odds of obesity in 2002-04 (1.84; 1.52-2.20, p < 0.0001). In women, higher VO2max (0.82; 0.72-0.93) resulted in lower odds of a 10 kg weight gain. CONCLUSIONS: The results indicate that cardiorespiratory fitness and previous BMI are important predictors of future weight gain and obesity, and should be incorporated in strategies to identify individuals at increased risk of obesity.
