Obesity and weight control practices in 2000 among veterans using VA facilities

OBJECTIVE: To examine obesity prevalence and weight control practices among veterans who use Department of Veterans Affairs (VA) medical facilities (VA users). RESEARCH METHODS AND PROCEDURES: Data from the 2000 Behavioral Risk Factor Surveillance System, a telephone survey of 184,450 adults, were analyzed. Outcome measures included BMI, weight control practices (the intent to manage weight, and diet and physical activity patterns), and receipt of professional weight control advice. RESULTS: Of VA users, 44% were overweight and 25% were obese. After controlling for demographic factors, VA users were somewhat less likely to be overweight (odds ratio, 0.86; 95% confidence interval, 0.74 to 1.00) but equally likely to be obese (odds ratio, 1.08; 95% confidence interval, 0.92 to 1.27), compared with non-VA users. Among obese VA users, 75% reported trying to lose weight, and another 17% reported trying to maintain weight. Of these, only 40% decreased both calorie and fat intake. Only 27% of obese VA users who reported increasing exercise to lose weight followed recommendations for regular and sustained physical activity. Of obese VA users, 59% were inactive or irregularly active. Only 51% of obese VA users received professional advice to lose weight. Obese VA users were more likely than obese non-VA users to report trying to lose weight, modifying diet to lose weight by decreasing both calories and fat intake, and receiving professional weight control advice. DISCUSSION: Interventions for weight management programs in VA facilities need to take into account the high prevalence of overweight/obesity among VA users and should emphasize effective weight control practices.     

Peer Reviewed: Lifestyle Behaviors and Physician Advice for Change Among Overweight and Obese Adults With Prediabetes and Diabetes in the United States, 2006

Introduction

The objective of this study was to examine the lifestyle behaviors of overweight and obese people with prediabetes or diabetes and to determine whether an association exists between reported behaviors and physician advice for behavior change.

Methods

This investigation included overweight and obese people (body mass index ≥25.0 kg/m²) with prediabetes and diabetes aged 40 years or older identified from the 2006 National Health Interview Survey. Respondents reported attempts to control or lose weight, reduce the amount of fat or calories in their diet, and increase physical activity. Respondents also reported receipt of a physician recommendation for behavioral change in 1 or more of these areas. Data analysis included use of logistic regression stratified by sex and prediabetes/diabetes status to model odds of behavior by physician advice.

Results

Most people reported trying to control or lose weight (prediabetes, 82%; diabetes, 75%). Fewer identified efforts to reduce the amount of fat or calories in their diet (prediabetes, 62%; diabetes, 71%) or increase physical activity (prediabetes, 53%; diabetes, 57%). Approximately one-third reported not receiving physician advice for each of these behavior changes. In logistic regression, physician advice for reducing the amount of fat or calories in the diet and increasing physical activity was generally associated with the reported corresponding behavior.

Conclusion

Many respondents reported trying to control or lose weight, but fewer reported actually reducing fat or calories in their diet or increasing physical activity. Physician advice may influence attempts at behavior change among overweight and obese patients with prediabetes and diabetes.     

Attempting to lose weight: specific practices among U.S. adults

BACKGROUND: Americans spend over $33 billion annually on weight-loss products and services. Although weight-control methods are of considerable public health interest, few national data on weight-loss practices are available. This paper examines the prevalence of specific weight-loss practices among U.S. adults trying to lose weight. METHODS: Data from the 1998 National Health Interview Survey, which was conducted through face-to-face interviews of a nationally representative sample of U.S. adults (n =32,440), were analyzed in 2003. RESULTS: Twenty-four percent of men and 38% of women were trying to lose weight. Attempting weight loss was less common among normal weight (body mass index [BMI]<25 kg/m(2)) people (6% men, 24% women) than overweight (BMI>/=25 to 30 kg/m(2)) people (28%, 49%) or obese (BMI>/=30 kg/m(2)) people (50%, 58%). Among those trying to lose weight, the most common strategies were eating fewer calories (58% men, 63% women); eating less fat (49%, 56%); and exercising more (54%, 52%). Less frequent strategies were skipping meals (11% men, 9% women); eating food supplements (5%, 6%); joining a weight-loss program (3%, 5%); taking diet pills (2%, 3%); taking water pills or diuretics (1%, 2%); or fasting for >/=24 hours (0.6%, 0.7%). Only one third of all those trying to lose weight reported eating fewer calories and exercising more. CONCLUSIONS: Increased efforts are needed among all those trying to lose weight to promote effective strategies for weight loss, including the use of calorie reduction and increased physical activity.     

Obesity in Inner‐city African Americans

Objective. Obesity, a risk factor for chronic diseases, has a high prevalence in African Americans and low‐income individuals. However, little is known about perceptions of overweight, attempts to lose weight, and strategies used to lose weight among African Americans in inner cities.

Design. A 1990 cross‐sectional telephone survey (n = 1445) of north St Louis and central Kansas City, USA.

Results. Obesity was common (44%) in this sample of inner‐city African Americans. The obese perceived themselves as overweight (70%) and were trying to lose weight (66%). The majority of the obese (68%) were both dieting and exercising to lose weight. Smoking prevalence was not higher among the obese or those trying to lose weight. Many of the obese had received medical advice recently on low‐fat diets (51%) and had been advised to lose weight (40%). Factors independently associated with perception, attempts to lose weight and medical advice differed, but included degree of obesity.

Conclusions. These results corroborate US national data that obesity is a public health problem in this population and that obese inner‐city African Americans perceive themselves as overweight and are trying to lose weight, especially as degree of obesity increases. It also appears that smoking is not being used as a weight loss strategy and that the obese, as a group, are receiving some medical advice on low‐fat diets. This information is critical for designing culturally sensitive weight‐control programmes.     

Diet and physical activity behaviors among Americans trying to lose weight: 2000 Behavioral Risk Factor Surveillance System

OBJECTIVE: To examine the prevalence and correlates of trying to lose weight among U.S. adults, describe weight loss strategies, and assess attainment of recommendations for weight control (eating fewer calories and physical activity). RESEARCH METHODS AND PROCEDURES: This study used the Behavioral Risk Factor Surveillance System, a state-based telephone survey of adults > or =18 years of age (N = 184,450) conducted in the 50 states, the District of Columbia, and Puerto Rico in 2000. RESULTS: The prevalence of trying to lose weight was 46% (women) and 33% (men). Women reported trying to lose weight at a lower BMI than did men; 60% of overweight women were trying to lose weight, but men did not reach this level until they were obese. Adults who had a routine physician checkup in the previous year and reported medical advice to lose weight vs. checkup and no medical advice to lose weight had a higher prevalence of trying to lose weight (81% women and 77% men vs. 41% women and 28% men, respectively). The odds of trying to lose weight increased as years of education increased. Among respondents who were trying to lose weight, approximately 19% of women and 22% of men reported using fewer calories and > or =150 min/wk leisure-time physical activity. DISCUSSION: A higher percentage of women than men were trying to lose weight; both sexes used similar weight loss strategies. Education and medical advice to lose weight were strongly associated with trying to lose weight. Most persons trying to lose weight were not using minimum recommended weight loss strategies.     

Physical activity, food choice, and weight management goals and practices among US college students

INTRODUCTION: Physical activity and a healthy diet have been recommended to help reverse the increasing prevalence of overweight among adolescents and adults in the United States. METHODS: Data is from the 1995 National College Health Risk Behavior Survey. A representative sample of US undergraduate college students (n = 4609) were analyzed to examine associations of physical activity and food choice with weight management goals and practices. RESULTS: Based on self-reported height and weight, 35% of students were overweight or obese (body mass index > or = 25.0). Nearly half (46%) of all students reported they were trying to lose weight. Female students were less likely than male students to be overweight, but more likely to be trying to lose weight. Among female and male students, using logistic regression to control for demographics, trying to lose weight was associated with participation in vigorous physical activity and strengthening exercises, and consumption of < or = 2 servings/ day of high-fat foods. Female and male students who reported using exercise to lose weight or to keep from gaining weight were more likely than those who did not to participate in vigorous, strengthening, and moderate physical activity, and were more likely to eat > or = 5 servings/day of fruits and vegetables and < or = 2 servings/day of high-fat foods. Among students who were trying to lose weight, only 54% of females and 41% of males used both exercise and diet for weight control. CONCLUSION: Colleges should implement programs to increase student awareness of healthy weight management methods and the importance of physical activity combined with a healthy diet.     

Perceived health risk of excess body weight among overweight and obese men and women: differences by sex

OBJECTIVES: To describe perceptions of health risk from excess body weight among adults, and assess if lack of perceived risk was associated with trying to lose weight. METHODS: Sex-specific logistic regression models were used to determine odds of disagreement that one's weight is a health risk and odds of trying to lose weight among overweight (BMI=25.0-29.9 kg/m(2), n=1296) and obese (BMI> or =30 kg/m(2), n=1335) adult participants in the 2004 Styles' surveys. RESULTS: Men were more likely than women to disagree their body weight was a health risk (among the overweight, 62% vs. 43%; the obese 20% vs. 14% obese). Disagreement with risk was associated with good health status and race/ethnicity among both sexes and lower education and income among women. Odds of currently trying to lose weight were significantly lower among obese men who disagreed, and overweight men and women who were neutral or disagreed that their body weight was a health risk. CONCLUSIONS: Many overweight and obese adults do not perceive their weight to be a health risk; this perception was associated with lower prevalence of trying to lose weight, particularly among men. Discussion by clinicians about the health risks of excess weight may alter perceived risk and help promote weight loss efforts.     

Geographic variation in the prevalence of obesity, diabetes, and obesity-related behaviors

OBJECTIVE: To examine the variation in the prevalences of obesity and type 2 diabetes in weight loss counseling by health providers and in other potential obesity-related determinants in 100 metropolitan statistical areas in the United States. RESEARCH METHODS AND PROCEDURES: We performed a cross-sectional study using data from the 2000 Behavioral Risk Factor Surveillance System, the largest telephone survey of health behaviors in the United States, of age-adjusted prevalence of obesity, type 2 diabetes, intake of >or=five servings of fruits and vegetables per day, participation in 150 minutes of leisure-time physical activity per week, receipt of weight management advice, and reports of trying to lose or maintain weight among men and women more than 18 years old. RESULTS: The age-adjusted prevalence of obesity ranged from 13.1% to 30.0% and that of type 2 diabetes from 3.3% to 9.2%. Among participants who had visited a physician for a routine checkup in the previous 12 months, 13.1% to 27.1% of all participants recalled receiving advice from a health professional about their weight, and 11.7% to 34.6% of overweight or obese participants recalled receiving advice to maintain or lose weight. DISCUSSION: Significant differences in the prevalence of obesity and self-reported type 2 diabetes and in medical practice patterns regarding weight management advice exist among metropolitan statistical areas. These results suggest important opportunities to investigate reasons for these variations that could potentially be used to mitigate the current epidemic of obesity and to identify areas where obesity and diabetes prevention efforts may need to be targeted.     

Assessing weight perception accuracy to promote weight loss among U.S. female adolescents: A secondary analysis

Background  

Overweight and obesity have become a global epidemic. The prevalence of overweight and obesity among U.S. adolescents has almost tripled in the last 30 years. Results from recent systematic reviews demonstrate that no single, particular intervention or strategy successfully assists overweight or obese adolescents in losing weight. An understanding of factors that influence healthy weight-loss behaviors among overweight and obese female adolescents promotes effective, multi-component weight-loss interventions. There is limited evidence demonstrating associations between demographic variables, body-mass index, and weight perception among female adolescents trying to lose weight. There is also a lack of previous studies examining the association of the accuracy of female adolescents' weight perception with their efforts to lose weight. This study, therefore, examined the associations of body-mass index, weight perception, and weight-perception accuracy with trying to lose weight and engaging in exercise as a weight-loss method among a representative sample of U.S. female adolescents.     

Arthritis, body mass index, and professional advice to lose weight: implications for clinical medicine and public health

BACKGROUND: Arthritis is the leading cause of disability in the United States. Obesity is a risk factor for arthritis, but the relationship between arthritis and weight has not been well characterized at the population level in the United States. Previous research shows that physicians often fail to advise their obese patients to lose weight. OBJECTIVES: To describe the relationship between body weight and arthritis in the United States, and to assess predictors of efforts to lose weight among obese adults with arthritis, including the impact of professional advice to lose weight. METHODS: Data from the 2000 Behavioral Risk Factor Surveillance System (a population-based survey of U.S. adults) from the 35 states that collected information on weight and height, arthritis, and efforts to lose weight. Arthritis was based on self-report of doctor diagnosis or chronic joint symptoms. Main outcome measures were arthritis and efforts to lose weight among adults with arthritis. RESULTS: Overall, 31.7% of respondents had self-reported arthritis. There was a strong relationship between body weight and arthritis. Specifically, the prevalence of arthritis was 25.9% among normal weight (18.5 to 24.9 body mass index [BMI]) adults; 32.1% among overweight (25 to 29.9 BMI) adults; and 43.5% among obese (>30 BMI) adults. This association persisted after adjusting for other factors (adjusted odds ratio [AOR] for having arthritis among obese individuals compared with healthy weight individuals, 3.6; 95% confidence interval [CI]=3.2-3.8). Among obese adults with arthritis who had a routine checkup within the past 12 months, only 43% were advised to lose weight by a health professional. However, recipients of such advice were more likely to try to lose weight than nonrecipients, and professional advice was the strongest independent predictor of weight loss efforts (AOR=2.8; 95% CI=2.5-3.1). CONCLUSIONS: Body mass index (BMI) is an important independent risk factor for self-reported arthritis. Although physicians often fail to advise obese adults with arthritis to lose weight, adults who report receiving such advice were more likely to report weight-loss efforts. Improved awareness of the relationship between arthritis and weight might help motivate patients to lose weight, and physician advice to lose weight could contribute to the prevention and treatment of arthritis.     

Weight management goals and practices among U.S. high school students: associations with physical activity, diet, and smoking.

PURPOSE: To examine associations of physical activity, fruit and vegetable consumption, and cigarette smoking with weight management goals and practices of U.S. high school students.METHODS: Data were from the 1999 national Youth Risk Behavior Survey, a representative sample of U.S. high school students (n = 15,349). Adjusted odds ratios (OR) were calculated to describe associations, controlling for demographic characteristics.RESULTS: Based on self-reported height and weight, 25% of students were either overweight (11%) or at risk for becoming overweight (14%). However, 43% of students were trying to lose weight and 19% of students were trying to maintain their current weight. Female students were less likely than male students to be overweight, but more likely to be trying to lose weight. Trying to lose weight was associated with vigorous physical activity (OR = 1.5), strengthening exercises (OR = 2.2), and cigarette smoking (OR = 1.4) among female students; and vigorous physical activity (OR = 1.6), strengthening exercises (OR = 1.8), and eating > or =5 servings/day of fruits and vegetables (OR = 1.5) among male students. Among students trying to lose weight or stay the same weight, only 62% of females and 41% of males combined exercise with a reduced fat and calorie diet, while 32% of females and 17% of males used unhealthy weight control methods (fasting, diet pills, vomiting, or laxatives).CONCLUSIONS: Efforts to promote healthy weight management among adolescents are needed and should place greater emphasis on combining physical activity with a reduced fat and calorie diet, increasing fruit and vegetable consumption, and discouraging smoking and other unhealthy weight control practices.     

Weight-loss strategies and beliefs in high and low socioeconomic areas of Melbourne

Abstract: Overweight is a serious health risk and is prevalent in Australia. This study explored sex, socioeconomic status and age differences in body mass index, the perceived effectiveness of weight-loss strategies and the frequency of their use, and awareness of the risks of obesity in a random sample of adult men (n = 457) and women (n = 537) from higher and lower socioeconomic areas. According to self-reports, 37 per cent of the sample were overweight or obese. More men than women, and more older than younger respondents, were overweight. There were no sex differences in the frequency of obesity. There were significantly more obese individuals in the lower than in the higher socioeconomic area. Women more frequently put themselves in a higher weight category while men more frequently put themselves in a lower weight category. Fifty-eight per cent of respondents reported the desire to lose weight and 24 per cent of the sample were trying to lose weight on the survey day; 46.9 per cent had attempted to lose weight in the previous 12 months, and these were more likely to be female, younger and obese or overweight. Only minor differences according to sex or socioeconomic status were found in beliefs about the effectiveness of different weight-loss strategies. However, older respondents were less likely to have exercised recently as a means of weight reduction. There was good recognition of diseases made worse by being overweight, although the health risk of male fat distribution patterns was not widely known.     

Health Care Providers' Advice on Lifestyle Modification for Older Adults

ObjectivesTo describe the pattern of health care providers' advice on lifestyle modification to older adults, and identify correlates of receiving such advice.DesignCross-sectional survey.Setting and participantsData from the National Health and Nutrition Examination Survey study from 2007-2016 on adults ≥65 years (n = 3758) were analyzed.MethodsWe estimated the weighted prevalence and correlates of receiving advice on the following lifestyle modifications: (1) increase physical activity, (2) reduce fat/calories, (3) control/lose weight, and (4) a combination of control/lose weight and physical activity. Data were analyzed according to level of comorbidity (number of chronic conditions including high blood pressure, high blood cholesterol, type 2 diabetes mellitus, coronary heart disease, and arthritis) and body mass index (BMI).ResultsPhysical activity was the most widely prescribed lifestyle modification, reported by 15.7% of older adults free of chronic conditions and 28.9%, 35.4%, and 52.6% of older adults with 1, 2, and ≥3 comorbidities. Advice on reducing fat/calories was reported by 9.2%, 18.5%, 26.3%, and 40.9% of older adults with 0, 1, 2, and ≥3 comorbidities, respectively, and advice on weight loss/control was reported by 6.5%, 19.1%, 20.8%, and 37.5%, respectively. The combination of advice on weight loss/control and physical activity was least commonly reported: 5.1%, 13.5%, 16.6%, and 32.0%, respectively. Overall, lifestyle modifications were more frequently advised to older adults who were overweight, obese, or Hispanic.Conclusions and implicationsIn the United States, lifestyle modifications are not routinely recommended to older adults, particularly those free of chronic conditions, presenting a missed opportunity for chronic disease prevention and management. Among those advised to lose or manage weight, concurrent advice to increase physical activity is not consistently provided.

Predictors of weight control advice in primary care practices: patient health and psychosocial characteristics

BACKGROUND: Past research has surveyed primary care physicians (PCP) about their attitudes and practices towards obese patients, yet less is known about the patients receiving advice. METHODS: The Primary Care Weight Control Project (PCWC) enrolled 18 PCPs in a randomized clinical trial and asked 255 of their patients who were either overweight or obese at baseline about past weight control advice. RESULTS: At baseline, 66.4% of patients reported that their physician previously told them they were overweight. Body mass index (BMI) was a strong predictor of being identified as obese. While 65.1% received information on the health benefits of weight loss, only 36.6% of patients were ever given specific weight control advice, and 28.2% were advised to increase their physical activity. A history of type 2 diabetes, high cholesterol, or hypertension was associated with physician-delivered weight control advice. Stages of change and number of prior visits with the PCP were also associated with physician advice. CONCLUSIONS: Patients were more likely to receive education about weight loss than specific behavioral advice on how to lose weight. Physicians were more likely to provide weight control advice to their patients who had obesity-related comorbidities than to patients who were overweight or obese and without risk factors.     

1985 NHIS findings: nutrition knowledge and baseline data for the weight-loss objectives

A nutrition objective for the nation is that, by 1990, 50 percent of the overweight population should have adopted weight regimens, balancing diet and physical activity. More than half of the overweight respondents in the 1985 National Health Interview Survey were trying to lose weight, and almost half of this group reported both increasing their physical activity and decreasing their intake of calories. Dietary restriction without exercise was the next most common weight-loss regimen, suggesting that educational efforts should emphasize the need to increase physical activity as part of appropriate weight-loss regimens. Attempts to lose weight were reported frequently among those of normal and lean weight as well as among those who were overweight, especially among women and the better educated. About one-fifth of already lean young women reported attempting weight loss, an indication that some inappropriate dieting is probably occurring, suggesting the need for caution in public health promotion of weight loss. Another 1990 objective is that 90 percent of adults should understand that eating fewer calories or increasing activity, or both, is essential to lose weight. More than 70 percent of adults in this survey were able to identify these as the two best ways to reduce weight, with greater proportions of the younger adults and the more highly educated being knowledgeable. The survey also provided data for an objective that targets some nutrition education and counseling as part of all routine health contacts with health professionals by 1990. Twenty-nine percent of all women and 22 percent of all men reported that eating proper foods was discussed sometimes or often in routine contacts.     

Association of energy intake and macronutrient composition with overweight and obesity in malay women from klang valley

This cross-sectional study investigates the association between energy intake and macronutrient composition of the diet with overweight and obesity among Malaysian women. One hundred and fifteen adult Malay women aged 20 to 59 years (mean age 37.2±7.6 years) were interviewed. Dietary intake was assessed using the food history method. Body weight status was assessed using weight, height, waist circumference and fat percentage measurements. When energy intake was assessed for accuracy, only 41% of the subjects (n=47) were normal energy reporters. Among the normal energy reporters, 55% were of normal weight whereas 32% and 13% were overweight and obese. Mean energy intake for normal weight, overweight and obese subjects was 1685±199 kcal/day, 1810±166 kcal/day and 2119±222 kcal/day, respectively. Energy intake increased with body mass index (BMI) category. Among the overweight and obese, energy intake was respectively higher by 125 kcal/day and 434 kcal/day as compared to their normal weight counterparts (p< 0.001). There was also a significant, moderate and positive correlation between energy intake and BMI (r=0.635), waist circumference (r=0.545), and body fat percentage (r=0.534). When macronutrient composition of diet was analysed (% energy and g/1000 kcal), there was no significant difference in carbohydrate, protein or fat intake between the obese, overweight and normal weight subjects. There was also no significant correlation between macronutrient composition of the diet and body weight status. Based on these findings, we conclude that the subjects' body weight status is likely to be influenced by energy intake rather than the macronutrient composition of the diet.     

Ecologic correlates of obesity in rural obese adults

OBJECTIVE: We examined relationships of individual and environmental factors with obesity and trying to lose weight in rural residents. METHODS: The joint contributions of individual and environmental factors on obesity status (obese vs. morbidly obese) and trying to lose weight (yes vs. no) were evaluated using generalized estimating equations. Patients at 29 clinics in rural areas (N = 414, M age 55.0 years (SD = 15.4), 66.3% female) completed anthropometric assessments of weight and height along with survey assessments of individual sociodemographics and trying to lose weight. Rural environments were assessed on aggregated physician access, and sociodemographic context. RESULTS: Most participants (70%, M BMI = 38.3) were obese and 30% morbidly obese. A majority (73%, n = 302) of the sample was trying to lose weight. Compared to obese, morbidly obese participants were more likely to be younger, disproportionately female, not have private insurance, have more comorbid conditions, and rate themselves in worse health in comparison to their obese peers. Compared to not trying to lose weight, trying to lose weight participants were more likely to be younger, disproportionately female, have fewer comorbid conditions, and have attempted to lose weight more times through exercise. Few relationships were seen between environmental variables and obesity or trying to lose weight. CONCLUSIONS: There was no consistent pattern of relationships between environment factors and obesity or trying to lose weight was seen. Unique aspects of rural living may not be captured by traditionally available neighborhood measures.     

Weight goals in a college-age population

OBJECTIVE: Although a growing body of literature has found unrealistic weight loss goals to be common among older, primarily female, subjects, little is known about weight loss goals of younger adults. RESEARCH METHODS AND PROCEDURES: Three hundred seventy-nine college students had their height and weight taken and reported their "goal," "dream," "happy," "acceptable," and "disappointed" weights. A series of 2 (gender) x 2 (nonoverweight vs. overweight) ANOVAs were conducted with both absolute weight goals and percentage of weight loss needed to obtain those goals as dependent variables. RESULTS: When examined in terms of absolute weight goals, women generally had lower body mass index (BMI) goals than men, and nonoverweight participants had lower BMI goals than overweight participants. Surprisingly, most overweight participants would accept a weight loss that would still place them in the overweight BMI range. When examined in terms of percentage loss needed to reach those goals, only overweight women chose goal and dream weights that would require a loss greater than can be expected from nonsurgical weight-loss treatments, and all overweight participants chose happy and acceptable weights within 15% of current weight. DISCUSSION: Participants in this study had generally reasonable weight-loss goals, and even the most extreme weight loss goals were much more moderate than those found in previous studies. These results are surprising given the extreme social pressures for thinness facing young adults. Future studies should examine the variables that influence selection of goal weights and how goal weights affect actual dieting behavior.     

Trying to Lose or Maintain Weight During Pregnancy—United States, 2003

Objectives Current pregnancy weight gain recommendations are for women to gain between 15 and 40 pounds; weight loss or weight maintenance is not recommended. However, for many women, overweight and obesity are chronic conditions, and commitment to weight loss or maintenance could override advice to gain weight during pregnancy. Our objective was to determine the prevalence of trying to lose or maintain weight among U.S. women during pregnancy. Methods The Behavioral Risk Factor Surveillance System is a state-based, random-digit-dialed telephone survey of noninstitutionalized, U.S. civilians aged ≥18 years. We identified women aged 18–44 years who reported being pregnant during 2003 (n = 2,464), assessed the prevalence of trying to lose or maintain weight and assessed independent associations with selected demographic, clinical, and behavioral factors using multinomial logistic regression. Results Among women who reported being pregnant, 7.5% (confidence interval [CI] = 5.7–9.8%) and 34.3% (CI = 31.0–37.7%) were trying to lose or maintain weight, respectively. Among women who reported trying to lose or maintain weight, exercise was a more prevalent weight control strategy than dietary change. After adjustment, women who drank alcohol during the past 30 days (Odds ratio [OR] = 8.86, CI: 4.51–17.42) or women who received advice in the past year to lose weight (OR = 9.10, CI: 3.20–25.87) were more likely to report trying to lose weight; women advised to maintain (OR = 0.20, CI: 0.07–0.60) or gain (OR = 0.04, CI: 0.01–0.23) weight were less likely to report trying to lose weight. Conclusions Despite guidelines to gain weight during pregnancy, about 8% and 34% of U.S. pregnant women reported trying to lose or maintain weight, respectively. Providers may encounter an increasing number of pregnant women whose weight control intentions conflict with current guidelines for pregnancy weight gain. Further research in this area is warranted. The conclusions in this report are those of the authors and do not necessarily reflect those of the Centers for Disease Control and Prevention.
