The influence of smoking cessation on the prevalence of overweight in the United States

Article Abstract:

Quitting smoking may be associated with weight gain among individuals and an overall increase in the number of people who are overweight. Researchers analyzed records of 5247 adults who participated in a US health survey consisting of interviews and physical exams conducted between 1988 and 1991. Adjusting for age and other factors, the average weight gain due to quitting smoking was 4.4 kilograms (kg) among men and 5.0 kg among women. Men who quit smoking in the previous 10 years were 2.4 times more likely to become overweight during that time than men who never smoked. Women who quit smoking in the previous 10 years were 2.0 time more likely to become overweight than women who had never smoked. However, the prevalence of overweight among people who quit more than 10 years before the survey was the same as the prevalence among people who never smoked.

Overweight prevalence and trends for children and adolescents: the National Health and Nutrition Examination Surveys, 1963 to 1991

Article Abstract:

An increased percentage of U.S. children appear to be overweight. Researchers compared data on body mass index (BMI) for children aged 6 to 17 years taken from a series of surveys carried out between 1963 and 1991. The BMI measures weight-for-height. Twenty-two percent of children surveyed between 1988 and 1991 had a BMI above what was the 85th percentile and 11% of children were in what was the upper 5% for surveys taken in the 1960s. The major increase in the percentage of overweight children took place between a survey covering 1976 to 1980 and the one covering 1988 to 1991. Between these time periods, the percentage of black children of both sexes and all ages and the percentage of white male teenagers exceeding the 85th percentile increased by 9% or more. Increases ranged from 2.5% to 5.5% among other race, sex, and age groupings.

The effect of age on the association between body-mass index and mortality

Article Abstract:

The risk of mortality may be higher among people who are overweight. Researchers compared mortality rates in a 12-year period among 62,116 men and 262,019 women aged 30 to 74 years. Greater body weight relative to height at the beginning of the study was associated with greater risk of death during the 12 years studied. The risk of death associated with excess body weight appeared to be more significant among younger participants in the study. Overall, the negative effect of excess body weight declined with age.
