To describe trends in calories available in large U.S. restaurants. Data were obtained from the MenuStat project, a census of menu items in 66 of the 100 largest U.S. restaurant chains, for 2012 and 2013 (N=19,417 items). Generalized linear models were used to calculate (1) the mean change in calories from 2012 to 2013, among items on the menu in both years; and (2) the difference in mean calories, comparing newly introduced items to those on the menu in 2012 only (overall and between core versus non-core items). Data were analyzed in 2014. Mean calories among items on menus in both 2012 and 2013 did not change. Large restaurant chains in the U.S. have recently had overall declines in calories in newly introduced menu items (-56 calories, 12% decline). These declines were concentrated mainly in new main course items (-67 calories, 10% decline). New beverage (-26...

Cross-sectional analysis of 24-h dietary recall data obtained from the National Health and Nutrition Examination Survey 2007-2010 (N=9440). Adults trying to lose weight consumed roughly 2000 total calories, 250 calories from SSBs, 225 calories from salty snacks, and 350 calories from sweet snacks. Adults not trying to lose weight consumed roughly 2300 total calories, 300 calories from SSBs, 250 calories from salty snacks, and 380 calories from sweet snacks. While overweight and obese adults trying to lose weight consumed fewer calories than those who were not, heavier adults trying to lose weight using dietary strategies or a combination of diet and physical activity consumed more calories than healthy weight adults using that same weight loss strategy (p<0.05). Price (>70%) and nutrition (>50%) were most when making food choices (p<0.05) ...

Examining these subpopulations is important as population averages may mask important differences. 24-hour dietary recall data obtained from the National Health and Nutrition Examination Survey 2003-2010 among children aged 2 to 19 (N = 14,092) were used. Logistic and linear regression methods were used to adjust for multiple covariates and survey design. The number of calories from SSBs declined significantly for nearly all age-specific body weight groups. Among overweight or obese children, significant declines in the number of calories from SSBs were observed among Hispanic children aged 2 to 5 (117 vs. 174 kcal) and white adolescents aged 12 to 19 (299 vs. 365 kcal). Significant declines in the number of calories from salty snacks were observed among white children aged 2 to 5 (192 to 134 kcal) and 6 to 11 (273 vs. 200 kcal). The decrease in SSB consumption and increase in snack consumption observed in prior research are not uniform when children are examined within subgroups accounting for age, weight, and race/ethnicity.

However, whether energy intake or expenditure is the dominant contributor to childhood obesity is a subject of debate. To date, no study has systematically reviewed the literature on this subject. We searched PubMed and Ovid Medline (January 1970 to January 2010) for potentially relevant English-language abstracts and obtained full-text articles for the abstracts, which passed the initial inclusion-exclusion criteria. Reference lists of full-length articles were hand searched to identify additional studies potentially relevant for inclusion. Relevant studies were characterized into one of the following three categories: cross-sectional studies with a nationally representative sample, cross-sectional studies among population subgroups and longitu...

The purpose of this study was to examine whether neighborhood- and individual-level characteristics affect providers' likelihood of providing an obesity diagnosis code in their obese patients' claims. Methods. Logistic regressions were performed with obesity diagnosis code serving as the outcome variable and neighborhood characteristics and member characteristics serving as the independent variables (N = 16,151 obese plan members). Results. Only 7.7 percent of obese plan members had an obesity diagnosis code listed in their claims. Members living in neighborhoods with the largest proportions of Blacks were 29 percent less likely to receive an obesity diagnosis (P < .05). The odds of having an obesity diagnosis code were greater among members who were female, aged 44 or below, hypertensive, dyslipidemic, BMI >/= 35 kg/m(2), had a larger number of provider visits, or who lived in an urban area (all P < .05). Conclusions. Most health care providers do not in...

Consumers of these beverages can be exposed to 4-methylimidazole (4-MEI), a potential carcinogen formed during its manufacture. California's Proposition 65 law requires that beverages containing 4-MEI concentrations corresponding to exposures that pose excess cancer risks > 1 case per 100,000 exposed persons (29 μg 4-MEI/day) carry warning labels. Using ultrahigh-performance liquid chromatography-tandem mass spectrometry, we assessed 4-MEI concentrations in 12 beverages purchased in California and a geographically distant metropolitan area (New York) in which warning labels are not required. In addition, we characterized beverage consumption by age and race/ethnicity (using weighted means calculated from logistic regressions) and assessed 4-MEI exposure and resulting cancer risks and US population cancer burdens attributable to beverage consumption. Data on beverage consumption were obtained from the Nati...

We conducted a national internet-based survey of 600 adults engaged in primary care with a BMI ≥ 25 kg/m(2) in 2012. Our dependent variable was high patient trust in their PCP (score ≥ 8/10). Our independent variable was &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;quot;feeling judged about my weight by my PCP&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;quot; dichotomized as &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;quot;often/sometimes&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;quot; versus &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;quot;never.&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;quot; We conducted a multivariate logistic regression model adjusted for patient and PCP factors using survey weights. Overall, 21% felt that their PCP judged them about their weight. Respondents who perceived judgment were significantly less likely to report high trust in their PCP [OR 0.55, 95% CI 0.31-0.98]. While only a fifth of overweight and obese patients perceived weight-related judgment from their PCPs, these patients were significantly less likely to report high trust in these providers. Given patients&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39; decreased trust in providers who convey weight-related judgment, our results raise concerns about potential effects on the doctor-patient relationship and patient outcomes. Addressing provider stigma toward patients with obesity could help build trust in these patient-provider relationships and improve quality of care.

Research paper thumbnail of Reducing Sugar-Sweetened Beverage Consumption by Providing Caloric Information: How Black Adolescents Alter Their Purchases and Whether the Effects Persist

We used a case-crossover design with 6 stores located in low-income Black neighborhoods in Baltimore, Maryland, from 2012 to 2013. The intervention used 1 of 4 randomly posted signs with caloric information: absolute calories, number of teaspoons of sugar, and number of minutes of running or miles of walking necessary to burn off a beverage. We collected data for 4516 purchases by Black adolescents, including both baseline and postintervention periods with no signs posted. We found that providing caloric information significantly reduced the number of total beverage calories purchased, the likelihood of buying an SSB, and the likelihood of buying an SSB greater than 16 ounces (P &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; .05). After removing the signs, the quantity, volume, and number of calories from SSB purchases remained lower than baseline (P &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; .05). Providing caloric information was associated with purchasing a smaller SSB, switching to a beverage with no calories, or opting to not purchase a beverage; there was a persistent effect on reducing SSB purchases after signs were removed.

Research paper thumbnail of Medicaid enrollment policy increased smoking cessation among pregnant women but had no impact on birth outcomes

These outcomes may be avoided or attenuated by timely, high-quality prenatal care. Using data from the Centers for Disease Control and Prevention's Pregnancy Risk Assessment Monitoring System for the period 2004-10, we examined the effects of two optional state Medicaid enrollment policies on smoking cessation, preterm birth, and having an infant who was small for gestational age. We used a natural experiment to compare outcomes before and after nineteen states adopted either of the two policies. The first policy, presumptive eligibility, permits women to receive prenatal care while their Medicaid application is pending. Its adoption led to a 7.7-percentage-point increase in smoking cessation but did not reduce adverse birth outcomes. The second policy, the unborn-child option, permits states to provide coverage to pregnant women who canno...

Using data from a national cohort of U.S. women conducted in 2005-2007 (N=2102), we employed propensity scores to match women who breastfed exclusively and non-exclusive for at least three months to comparison women who had not breastfed or breastfed for less than three months. Outcomes included postpartum weight loss at 3, 6, 9, and 12months postpartum; and the probability of returning to pre-pregnancy body mass index (BMI) category and the probability of returning to pre-pregnancy weight. Compared to women who did not breastfeed or breastfed non-exclusively, exclusive breastfeeding for at least 3months resulted in 3.2 pound (95% CI: 1.4,4.7) greater weight loss at 12months postpartum, a 6.0-percentage-point increase (95% CI: 2.3,9.7) in the probability of returning to the same or lower BMI category postpartum; and a 6.1-percentage-point increase (9...

A 2014 national cross-sectional online survey of 500 U.S. nonphysician health professionals (100 from each: nutrition, nursing, behavioral/mental health, exercise, pharmacy) was analyzed. Nutrition professionals most commonly self-identified as the most qualified group to help patients lose weight (92%), sentiments supported by other health professionals (57%). The most often cited challenge was lack of patient adherence (87%). Among nutrition professionals, 77% reported receiving high-quality training in weight loss counseling. Nutrition professionals who reported high-quality training were significantly more likely to report confidence (95% vs. 48%) and success (74 vs. 50%) in helping obese patients lose weight (P&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt;0.05) than those reporting lower-quality training. Across all nonphysician health professionals, nutrition professionals were identified as best suited to provide routine weight management counseling to obese patients. Yet nutrition professionals&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39; receipt of high-quality weight management training appears critical to their success in helping patients lose weight.

A national cross-sectional Internet-based survey of 500 US non-physician health professionals specializing in nutrition, nursing, behavioral/mental health, exercise, and pharmacy collected between January 20 and February 5, 2014 was analyzed. Normal-BMI professionals were more likely than overweight/obese professionals to report success in helping patients achieve clinically significant weight loss (52% vs. 29%, P = 0.01). No differences by health professional BMI about the appropriate patient body weight for weight-related care (initiate weight loss discussions and success in helping patients lose weight), confidence in ability to help patients lose weight, or in perceived patient trust in their advice were observed. Most health professionals (71%) do not feel successful in helping patients lose weight until they are morbidly obese, regardless of BMI. Normal-BMI non-physician health professionals report being more successful than overweight and obese health professionals at helping obese patients lose weight. More research is needed to understand how to improve self-efficacy for delivering obesity care, particularly among overweight and class I obese patients.

The odds of having an obesity diagnosis code were greater among members who were female, aged 44 or below, hypertensive, dyslipidemic, BMI >/= 35 kg/m(2), had a larger number of provider visits, or who lived in an urban area (all P < .05). Conclusions. Most health care providers do not in...

Consumers of these beverages can be exposed to 4-methylimidazole (4-MEI), a potential carcinogen formed during its manufacture. California's Proposition 65 law requires that beverages containing 4-MEI concentrations corresponding to exposures that pose excess cancer risks > 1 case per 100,000 exposed persons (29 μg 4-MEI/day) carry warning labels. Using ultrahigh-performance liquid chromatography-tandem mass spectrometry, we assessed 4-MEI concentrations in 12 beverages purchased in California and a geographically distant metropolitan area (New York) in which warning labels are not required. In addition, we characterized beverage consumption by age and race/ethnicity (using weighted means calculated from logistic regressions) and assessed 4-MEI exposure and resulting cancer risks and US population cancer burdens attributable to beverage consumption. Data on beverage consumption were obtained from the Nati...

We conducted a national internet-based survey of 600 adults engaged in primary care with a BMI ≥ 25 kg/m(2) in 2012. Our dependent variable was high patient trust in their PCP (score ≥ 8/10). Our independent variable was &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;quot;feeling judged about my weight by my PCP&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;quot; dichotomized as &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;quot;often/sometimes&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;quot; versus &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;quot;never.&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;quot; We conducted a multivariate logistic regression model adjusted for patient and PCP factors using survey weights. Overall, 21% felt that their PCP judged them about their weight. Respondents who perceived judgment were significantly less likely to report high trust in their PCP [OR 0.55, 95% CI 0.31-0.98]. While only a fifth of overweight and obese patients perceived weight-related judgment from their PCPs, these patients were significantly less likely to report high trust in these providers. Given patients&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39; decreased trust in providers who convey weight-related judgment, our results raise concerns about potential effects on the doctor-patient relationship and patient outcomes. Addressing provider stigma toward patients with obesity could help build trust in these patient-provider relationships and improve quality of care.

Research paper thumbnail of Reducing Sugar-Sweetened Beverage Consumption by Providing Caloric Information: How Black Adolescents Alter Their Purchases and Whether the Effects Persist

We used a case-crossover design with 6 stores located in low-income Black neighborhoods in Baltimore, Maryland, from 2012 to 2013. The intervention used 1 of 4 randomly posted signs with caloric information: absolute calories, number of teaspoons of sugar, and number of minutes of running or miles of walking necessary to burn off a beverage. We collected data for 4516 purchases by Black adolescents, including both baseline and postintervention periods with no signs posted. We found that providing caloric information significantly reduced the number of total beverage calories purchased, the likelihood of buying an SSB, and the likelihood of buying an SSB greater than 16 ounces (P &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; .05). After removing the signs, the quantity, volume, and number of calories from SSB purchases remained lower than baseline (P &amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt; .05). Providing caloric information was associated with purchasing a smaller SSB, switching to a beverage with no calories, or opting to not purchase a beverage; there was a persistent effect on reducing SSB purchases after signs were removed.

Research paper thumbnail of Medicaid enrollment policy increased smoking cessation among pregnant women but had no impact on birth outcomes

These outcomes may be avoided or attenuated by timely, high-quality prenatal care. Using data from the Centers for Disease Control and Prevention's Pregnancy Risk Assessment Monitoring System for the period 2004-10, we examined the effects of two optional state Medicaid enrollment policies on smoking cessation, preterm birth, and having an infant who was small for gestational age. We used a natural experiment to compare outcomes before and after nineteen states adopted either of the two policies. The first policy, presumptive eligibility, permits women to receive prenatal care while their Medicaid application is pending. Its adoption led to a 7.7-percentage-point increase in smoking cessation but did not reduce adverse birth outcomes. The second policy, the unborn-child option, permits states to provide coverage to pregnant women who canno...

Using data from a national cohort of U.S. women conducted in 2005-2007 (N=2102), we employed propensity scores to match women who breastfed exclusively and non-exclusive for at least three months to comparison women who had not breastfed or breastfed for less than three months. Outcomes included postpartum weight loss at 3, 6, 9, and 12months postpartum; and the probability of returning to pre-pregnancy body mass index (BMI) category and the probability of returning to pre-pregnancy weight. Compared to women who did not breastfeed or breastfed non-exclusively, exclusive breastfeeding for at least 3months resulted in 3.2 pound (95% CI: 1.4,4.7) greater weight loss at 12months postpartum, a 6.0-percentage-point increase (95% CI: 2.3,9.7) in the probability of returning to the same or lower BMI category postpartum; and a 6.1-percentage-point increase (9...

A 2014 national cross-sectional online survey of 500 U.S. nonphysician health professionals (100 from each: nutrition, nursing, behavioral/mental health, exercise, pharmacy) was analyzed. Nutrition professionals most commonly self-identified as the most qualified group to help patients lose weight (92%), sentiments supported by other health professionals (57%). The most often cited challenge was lack of patient adherence (87%). Among nutrition professionals, 77% reported receiving high-quality training in weight loss counseling. Nutrition professionals who reported high-quality training were significantly more likely to report confidence (95% vs. 48%) and success (74 vs. 50%) in helping obese patients lose weight (P&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;lt;0.05) than those reporting lower-quality training.

A national cross-sectional Internet-based survey of 500 US non-physician health professionals specializing in nutrition, nursing, behavioral/mental health, exercise, and pharmacy collected between January 20 and February 5, 2014 was analyzed. Normal-BMI professionals were more likely than overweight/obese professionals to report success in helping patients achieve clinically significant weight loss (52% vs. 29%, P = 0.01). No differences by health professional BMI about the appropriate patient body weight for weight-related care (initiate weight loss discussions and success in helping patients lose weight), confidence in ability to help patients lose weight, or in perceived patient trust in their advice were observed. Most health professionals (71%) do not feel successful in helping patients lose weight until they are morbidly obese, regardless of BMI. Normal-BMI non-physician health professionals report being more successful than overweight and obese health professionals at helping obese patients lose weight. More research is needed to understand how to improve self-efficacy for delivering obesity care, particularly among overweight and class I obese patients.
