ABSTRACT

In 2016, New York City (NYC) began enforcing a sodium warning regulation at chain restaurants, requiring placement of an icon next to any menu item containing ≥2,300 mg sodium. As menu labeling may improve menu nutritional composition, we investigated whether sodium content of menu items changed following enforcement of the sodium warning icon. All menu offerings at 10 quick-service (QSR) and 3 full-service (FSR) chain restaurants were photographed in 2015 (baseline) and 2017 (follow-up) and matched to nutritional information from restaurant websites; items were categorized as being available at both baseline and follow-up, or at only one timepoint. Linear and logistic regression models, respectively, assessed changes in calculated mean sodium-per-serving per menu item and the odds of an item containing ≥2,300 mg sodium. At baseline, mean per-serving sodium content was 2,160 mg at FSR and 1,070 mg at QSR, and 40.6% of FSR items and 7.2% of QSR items contained ≥2,300 mg sodium per serving. Sodium content did not differ when comparing all items offered at follow-up to all offered at baseline (21 mg, 95% CI: -60,101), or when comparing new versus discontinued items (17 mg, 95% CI: -154, 187). At follow-up, there was no change in the overall likelihood of items requiring a warning icon (OR = 1.32, 95% CI: 0.97,1.79), or when comparing new versus discontinued items (OR = 2.08, 95% CI: 1.02,4.24) (p = 0.04, not significant following Bonferroni correction for multiple analyses). Our findings that the sodium content of menu items did not change following the sodium warning icon regulation underscore difficulties in reducing sodium levels in restaurants; however, our results may be limited by follow-up data collection occurring less than one year post-enforcement. It may take additional time and similar action from other jurisdictions for restaurants to reduce the sodium content of menu items.

ABSTRACT

In 2016, New York City (NYC) began enforcing a sodium warning regulation at chain restaurants, requiring placement of an icon next to any menu item containing ≥2,300 mg sodium. As shifts in consumer purchases are a potential outcome of menu labeling, we investigated whether high-sodium purchases from NYC chains changed following policy implementation. Using receipts for verification, consumer purchases were assessed at 2 full-service (FSR) and 2 quick-service (QSR) chain restaurants in NYC and Yonkers, NY, which did not implement sodium menu labeling, in 2015 and 2017. Primary outcomes included the proportion of respondents purchasing high-sodium item(s) (containing ≥2,300 mg sodium) and mean sodium content of purchases; changes were assessed by difference-in-difference regression models, adjusted for demographic and location co-variates. At both FSR and QSR, there was not a significant change in the proportion of NYC respondents purchasing 1 or more high-sodium items, relative to Yonkers (FSR difference-in-difference: -4.6%, p = 0.364; QSR difference-in-difference: -8.9%, p = 0.196). Among NYC FSR respondents, mean sodium content of purchases significantly declined compared to Yonkers (difference-in-difference: -524 mg, p = 0.012); no changes in mean sodium were observed among QSR participants (difference-in-difference: 258 mg, p = 0.185). Although there was a reduction in mean sodium content of purchases among NYC FSR patrons following sodium warning icon implementation, the mechanism behind the relatively larger NYC decline is unknown.

ABSTRACT

Since 2006, New York City (NYC) has attempted to reduce sugary drink consumption through several population-based initiatives, media campaigns and policy proposals. We estimated trends in the relative market share of sugary drinks and other beverage categories in NYC, using over 5 years of weekly, point-of-sale data from a retailer sample. We used an interrupted time series approach to assess whether changes in NYC beverage purchasing patterns occurred following the announcement of a proposed portion cap rule for consumer purchases of sugary drinks. Overall, market share of sugary drinks declined in NYC between 2010 and 2015. While the proportion of beverage volume sold that was sugary drinks was stable prior to the May 2012 portion cap rule announcement, decreases of 1.25% per year were observed in the period following the announcement compared to the period before (95% confidence interval (CI) - 1.60, - 0.90). Water/seltzer market share was increasing prior to the announcement and increased by an additional 1.03% per year in the post-announcement period (95% CI 0.48, 1.57). City-led efforts to increase public awareness about sugary drink-associated health risks in NYC may have led to reductions in consumer purchases of these beverages. Though never implemented, the portion cap proposal and accompanying media coverage may have contributed to decreases in sugary drink sales.

ABSTRACT

BACKGROUND: Tobacco advertising in retailers influences smoking, but little research has examined how this relationship differs among population subgroups. This study merged data on neighborhood cigarette advertising with geocoded survey data to assess the association between advertising prevalence and current smoking among New York City (NYC) residents, and whether demographic and psychological characteristics moderate this relationship. METHODS: Audit data from a stratified, random sample of 796 NYC tobacco retailers generated neighborhood prevalence estimates of cigarette advertising, which were linked with unweighted 2017 NYC Community Health Survey data (n = 7837 adult respondents with residential geocodes). Multilevel regression estimated adjusted odds ratios (aOR) of current smoking by level of neighborhood cigarette advertising (quartiles). Interactions assessed differences in this relationship by demographic characteristics and current depression (analyses conducted in 2019). RESULTS: There was no main effect of advertising on smoking status or significant interactions with demographic variables, but current depression was an effect modifier (p = 0.045). Cigarette advertising was associated with current smoking among those with current depression (p = 0.023), not those without (p = 0.920). Specifically, respondents with depression who resided in neighborhoods in the highest quartile for cigarette advertising prevalence had higher odds of current smoking, compared to those living in the lowest advertising quartile [aOR: 1.72 (1.04, 2.86)]. CONCLUSION: Retail cigarette advertising may serve as an environmental cue to smoke among adults with depression. Efforts to restrict or counteract this practice, such as the development of community-level public health interventions and counter-marketing programs, may particularly benefit those with depression and, perhaps, other mental health disorders.

ABSTRACT

Objectives: We assessed differences in trends, prevalence, and sociodemographic correlates of current smoking among several predominant Hispanic/Latino heritage groups (Puerto Ricans, Dominicans, Central and South Americans, and other Hispanic/Latinos) in New York City (NYC). We additionally compared current smoking prevalence between heritage groups and non-Hispanic/Latino Whites. Design and Methods: Data from the Community Health Survey, a representative, dual-frame landline/cellphone survey, were analyzed to assess age-adjusted prevalence of current smoking, separately among heritage groups from 2003-2016. Logistic regression was used to estimate odds ratios and 95% CIs for current smoking by Hispanic/Latino heritage group relative to non-Hispanic/Latino Whites in combined 2012-2016 data. Logistic regression was also used to examine correlates of smoking among each heritage group, separately. Results: Between 2003-2016, current smoking prevalence decreased among all Hispanic/Latinos heritage groups except Puerto Ricans, who had the highest smoking prevalence among all groups examined. Sex-stratified trend analyses showed decreases among all groups except Puerto Rican and other Hispanic/Latino males. In multivariable-adjusted models, relative to non-Hispanic/Latino Whites, there was no association with current smoking among Puerto Ricans, but odds of smoking were lower among all other heritage groups. Female sex was inversely associated with current smoking among all heritage groups, and acculturation was positively associated with smoking among all groups except Central/South Americans. Lower educational attainment was strongly associated with smoking among Puerto Ricans. Conclusions: Lack of progress in reducing smoking among Puerto Ricans in NYC is concerning. Opportunities for cultural, sex-specific, and other targeted outreach to this community should be explored.

ABSTRACT

Background: Estrogen metabolism in premenopausal women may be related to early life body fatness.Methods: Premenopausal women participating in the Nurses' Health Study II recalled their body fatness at ages 5, 10, and 20 years using a validated 9-level pictogram. Fifteen estrogens and estrogen metabolites (EM) were measured using LC/MS-MS in luteal phase urines from 603 women ages 32-54 years. Geometric means of individual EM, metabolic pathway groups, and pathway ratios were examined by body fatness categories using linear mixed models.Results: Body fatness at each age was inversely associated with adult concentrations of all EM combined, parent estrogens (estrone, estradiol), and the 2-hydroxylation pathway. Women in the top (vs. bottom) category of body fatness at age 10 had 21% lower levels of all EM (Ptrend = 0.003), 24% lower parent estrogens (Ptrend = 0.002), and 36% lower 2-pathway (Ptrend = 0.0003). Body fatness at age 10 was inversely associated with 2-catechols (35% lower, Ptrend = 0.0004) and 2-methylated catechols (30% lower, Ptrend = 0.002). After adjusting for premenopausal body mass index (BMI), these associations remained inverse but were attenuated; only parent estrogens remained statistically significant (21% lower, Ptrend = 0.01). Body fatness at ages 5 and 20 were similarly, but more weakly, associated with estrogen pathways.Conclusions: Estimates of body fatness during early life were inversely associated with premenopausal levels of all EM combined, parent estrogens, and 2-pathway estrogen metabolites. These relationships were not fully explained by adult BMI.Impact: These findings inform investigations of diseases linked to early life body fatness and estrogen metabolism.

ABSTRACT

BACKGROUND: Previous population-based studies have described first primary breast cancer tumor characteristics and their association with contralateral breast cancer (CBC) risk. However, information on influential covariates such as treatment, family history of breast cancer, and BRCA1/2 mutation carrier status was not available. In a large, population-based, case-control study, we evaluated whether tumor characteristics of the first primary breast cancer are associated with risk of developing second primary asynchronous CBC, overall and in subgroups of interest, including among BRCA1/2 mutation non-carriers, women who are not treated with tamoxifen, and women without a breast cancer family history. METHODS: The Women's Environmental Cancer and Radiation Epidemiology Study is a population-based case-control study of 1521 CBC cases and 2212 individually-matched controls with unilateral breast cancer. Detailed information about breast cancer risk factors, treatment for and characteristics of first tumors, including estrogen receptor (ER) and progesterone receptor (PR) status, was obtained by telephone interview and medical record abstraction. Multivariable risk ratios (RRs) and 95% confidence intervals (CIs) were estimated in conditional logistic regression models, adjusting for demographics, treatment, and personal medical and family history. A subset of women was screened for BRCA1/2 mutations. RESULTS: Lobular histology of the first tumor was associated with a 30% increase in CBC risk (95% CI 1.0-1.6). Compared to women with ER+/PR+ first tumors, those with ER-/PR- tumors had increased risk of CBC (RR = 1.4, 95% CI 1.1-1.7). Notably, women with ER-/PR- first tumors were more likely to develop CBC with the ER-/PR- phenotype (RR = 5.4, 95% CI 3.0-9.5), and risk remained elevated in multiple subgroups: BRCA1/2 mutation non-carriers, women younger than 45 years of age, women without a breast cancer family history, and women who were not treated with tamoxifen. CONCLUSIONS: Having a hormone receptor negative first primary breast cancer is associated with increased risk of CBC. Women with ER-/PR- primary tumors were more likely to develop ER-/PR- CBC, even after excluding BRCA1/2 mutation carriers. Hormone receptor status, which is routinely evaluated in breast tumors, may be used clinically to determine treatment protocols and identify patients who may benefit from increased surveillance for CBC.

ABSTRACT

In a cross-sectional analysis, we evaluated the associations of usual total alcohol and wine intake with a comprehensive profile of mid-luteal phase urinary estrogens and estrogen metabolites (referred to jointly as EM) in a sample of 603 premenopausal women participating in the Nurses' Health Study II (NHSII). A total of 15 individual EM (pmol/mg creatinine) were measured by a liquid chromatography/tandem mass spectrometry (LC-MS/MS) method with high accuracy and reproducibility. We used linear mixed models to calculate the adjusted geometric means of individual EM, EM grouped by metabolic pathways, and pathway ratios by category of alcohol intake with non-drinkers of alcohol as the referent. Total alcohol intake was not associated with total EM but was positively associated with estradiol (26% higher among women consuming >15 g/day vs. non-drinkers; P trend = 0.03). Wine consumption was positively associated with a number of EM measures including estradiol (22% higher among women consuming ≥ 5 drinks/week vs. non-drinkers, P trend < 0.0001). In conclusion, the total alcohol intake was positively and significantly associated with urinary estradiol levels. Some differences in urinary estrogen metabolites were observed with wine drinking, when compared with non-drinkers. This study strengthens the evidence that alcohol consumption might play a role in breast cancer and other estrogen-related conditions. Additional studies of premenopausal women are needed to further explore the association of alcohol, particularly the specific types of alcohol, on patterns of estrogen metabolism in blood, urine, and tissue.

ABSTRACT

Several intrinsic breast cancer subtypes, possibly representing unique etiologic processes, have been identified by gene expression profiles. Evidence suggests that associations with reproductive risk factors may vary by breast cancer subtype. In the Nurses' Health Studies, we prospectively examined associations of reproductive factors with breast cancer subtypes defined using immunohistochemical staining of tissue microarrays. Multivariate-adjusted Cox proportional hazard models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). Over follow-up, we identified 2,063 luminal A, 1,008 luminal B, 209 HER2-enriched, 378 basal-like and 110 unclassified tumors. Many factors appeared associated with luminal A tumors, including ages at menarche (p(heterogeneity) = 0.65) and menopause (p(heterogeneity) = 0.05), and current HT use (p(heterogeneity) = 0.33). Increasing parity was not associated with any subtype (p(heterogeneity) = 0.76), though age at first birth was associated with luminal A tumors only (per 1-year increase HR = 1.03 95%CI (1.02-1.05), p(heterogeneity) = 0.04). Though heterogeneity was not observed, duration of lactation was inversely associated with risk of basal-like tumors only (7+ months vs. never HR = 0.65 95%CI (0.49-0.87), ptrend = 0.02), p(heterogeneity) = 0.27). Years between menarche and first birth was strongly positively associated with luminal A and non-luminal subtypes (e.g. 22-year interval vs. nulliparous HR = 1.80, 95%CI (1.08-3.00) for basal-like tumors; p(heterogeneity) = 0.003), and evidence of effect modification by breastfeeding was observed. In summary, many reproductive risk factors for breast cancer appeared most strongly associated with the luminal A subtype. Our results support previous reports that lactation is protective against basal-like tumors, representing a potential modifiable risk factor for this aggressive subtype.

ABSTRACT

BACKGROUND: Prior studies have found weak inverse associations between breast cancer and caffeine and coffee intake, possibly mediated through their effects on sex hormones. METHODS: High-performance liquid chromatography/tandem mass spectrometry was used to quantify levels of 15 individual estrogens and estrogen metabolites (EM) among 587 premenopausal women in the Nurses' Health Study II with mid-luteal phase urine samples and caffeine, coffee, and/or tea intakes from self-reported food frequency questionnaires. Multivariate linear mixed models were used to estimate geometric means of individual EM, pathways, and ratios by intake categories, and P values for tests of linear trend. RESULTS: Compared with women in the lowest quartile of caffeine consumption, those in the top quartile had higher urinary concentrations of 16α-hydroxyestrone (28% difference; Ptrend = 0.01) and 16-epiestriol (13% difference; Ptrend = 0.04), and a decreased parent estrogens/2-, 4-, 16-pathway ratio (Ptrend = 0.03). Coffee intake was associated with higher 2-catechols, including 2-hydroxyestradiol (57% difference, ≥4 cups/day vs. ≤6 cups/week; Ptrend = 0.001) and 2-hydroxyestrone (52% difference; Ptrend = 0.001), and several ratio measures. Decaffeinated coffee was not associated with 2-pathway metabolism, but women in the highest (vs. lowest) category of intake (≥2 cups/day vs. ≤1-3 cups/month) had significantly lower levels of two 16-pathway metabolites, estriol (25% difference; Ptrend = 0.01) and 17-epiestriol (48% difference; Ptrend = 0.0004). Tea intake was positively associated with 17-epiestriol (52% difference; Ptrend = 0.01). CONCLUSION: Caffeine and coffee intake were both associated with profiles of estrogen metabolism in premenopausal women. IMPACT: Consumption of caffeine and coffee may alter patterns of premenopausal estrogen metabolism.

ABSTRACT

High levels of circulating carotenoids are hypothesized to reduce breast cancer risk, potentially due to their antioxidant properties. However, little is known about the relationship between carotenoid exposure earlier in life and risk. We examined associations of premenopausal plasma carotenoids and markers of oxidative stress and risk of breast cancer among 1179 case-control pairs in the Nurses' Health Study (NHS) and NHSII. Levels of α- and ß-carotene, ß-cryptoxanthin, lycopene, and lutein/zeaxanthin were quantified by high-performance liquid chromatography. Three fluorescent oxidation products (FlOP_360, FlOP_320, FlOP_400) were measured in a subset of participants by spectrofluoroscopy. Multivariate conditional logistic regression was used to estimate odds ratios and 95 % confidence intervals for breast cancer by quartile, as well as P values for tests of linear trend. We additionally examined whether 45 single-nucleotide polymorphisms (SNPs) in five genes involved in oxidative and antioxidative processes or carotenoid availability were associated with risk. Carotenoid measures were not inversely associated with breast cancer risk. No differences by estrogen receptor status were observed, though some inverse associations were observed among women postmenopausal at diagnosis. Plasma FlOP levels were not positively associated with risk, and suggestive inverse associations with FlOP_320 and FlOP_360 were observed. Several SNPs were associated with carotenoid levels, and a small number were suggestively associated with breast cancer risk. We observed evidence of interactions between some SNPs and carotenoid levels on risk. We did not observe consistent associations between circulating levels of premenopausal carotenoids or FlOP levels and breast cancer risk.

ABSTRACT

Several reproductive factors are known to be associated with risk of breast cancer; however, relationships between these factors with risk of second primary asynchronous contralateral breast cancer (CBC) have not been widely studied. The Women's Environmental, Cancer, and Radiation Epidemiology (WECARE) Study is a population-based case-control study of 1521 CBC cases and 2212 individually matched controls with unilateral breast cancer. Using multivariable conditional logistic regression models, we examined associations between reproductive factors and CBC risk, and whether associations differed by estrogen receptor (ER) status and menopausal status of the first breast cancer. Older age at menarche was inversely associated with CBC risk (≥14 vs. ≤11 years risk ratio (RR) = 0.82, 95 % confidence interval (CI) 0.65-1.03, P trend = 0.02). Among parous women, an increasing number of full-term pregnancies (FTP) was inversely associated with risk (≥4 vs. 1 FTP RR = 0.60, 95 % CI 0.41-0.88, P trend = 0.005). Ever breast-feeding was inversely associated with CBC risk only among women with ER-negative first tumors (ever vs. never breast-fed RR = 0.69, 95 % CI 0.48-1.00, P heterogeneity = 0.05). Older age at first FTP was inversely associated with CBC risk among women with ER-negative first tumors (≥30 vs. <20 years old RR = 0.66, 95 % CI 0.35-1.27, P trend = 0.03), but suggestively positively associated with risk among women with ER-positive first tumors (P heterogeneity = 0.03). Young age at menarche and low parity, both risk factors for first primary breast cancer, were also associated with overall CBC risk. Reductions in risk associated with breast-feeding were limited to women with ER-negative first tumors, who are at higher CBC risk than women with ER-positive primaries.
