    Aspirin Use is Associated With Lower Risk of Barrett’s Esophagus in Women
    (Nature Publishing Group, 2017) Jovani, Manol; Cao, Yin; Feskanich, Diane; Drew, David; Hur, Chin; Fuchs, Charles S; Jacobson, Brian C; Chan, Andrew
    Objectives: Barrett’s esophagus (BE) is the only known precursor to esophageal adenocarcinoma. Data examining the association of aspirin with the onset of BE, particularly for women, are scant and conflicting. Methods: We leveraged data from 121,700 women enrolled in the Nurses’ Health Study, a large prospective cohort study, who biennially provided detailed information regarding endoscopy and use of aspirin. We used unconditional logistic regression to obtain multivariable (MV)-adjusted odds ratios (ORs) and 95% confidence intervals (CI) to estimate the risk of BE in regular aspirin users (≥2 times/week) compared to non-regular users. Results: Among 27,881 women who had undergone upper GI endoscopy, we documented 667 BE cases over 18 years of follow-up. Compared to non-regular users, women who regularly used aspirin had a MV-adjusted OR for BE of 0.85 (95%CI: 0.72, 0.99). The corresponding OR was 0.73 (95%CI: 0.56, 0.96) for BE at least 1 cm long. Compared with women who did not use any aspirin, the MV-adjusted OR for any BE was 0.91 (95% CI, 0.69, 1.20) for women taking 0.5-1.5 tablets/week; 0.92 (95%CI 0.76, 1.11) for 2–5 tablets/week; and 0.71 (95%CI 0.55, 0.92) for ≥6 tablets/week (p-trend=0.01). Compared with non-regular users, the MV-adjusted OR for BE risk was 0.90 (95%CI 0.67, 1.20) for women who regularly used aspirin for 1–5 years, 0.84 (95%CI 0.65, 1.09) for 6–10 years, and 0.81 (95%CI 0.67, 0.97) for >10 years (p-trend=0.03). Conclusion: Regular aspirin use was associated with a reduction in the risk of Barrett’s esophagus in women. The reduction in risk appeared related to higher dose and longer duration of use.

    A Preliminary Evaluation of the Ability of Keratotic Tissue to Act as a Prognostic Indicator of Hip Fracture Risk
    (SAGE Publications, 2018) Beattie, J Renwick; Feskanich, Diane; Caraher, M Clare; Towler, Mark R
    Studies have shown that Raman spectroscopic analysis of fingernail clippings can help differentiate between post-menopausal women who have and who have not suffered a fracture. However, all studies to date have been retrospective in nature, comparing the proteins in nails sourced from women, post-fracture. The objective of this study was to investigate the potential of a prospective test for hip fracture based on spectroscopic analysis of nail tissue. Archived toenail samples from post-menopausal women aged 50 to 63 years in the Nurses’ Health Study were obtained and analysed by Raman spectroscopy. Nails were matched case-controls sourced from 161 women; 82 who underwent a hip fracture up to 20 years after nail collection and 81 age-matched controls. A number of clinical risk factors (CRFs) from the Fracture Risk Assessment (FRAX) tool had been assessed at toenail collection. Using 80% of the spectra, models were developed for increasing time periods between nail collection and fracture. Scores were calculated from these models for the other 20% of the sample and the ability of the score to predict hip fracture was tested in model with and without the CRFs by comparing the odds ratios (ORs) per 1 SD increase in standardised predictive values. The Raman score successfully distinguished between hip fracture cases and controls. With only the score as a predictor, a statistically significant OR of 2.2 (95% confidence interval [CI]: 1.5-3.1) was found for hip fracture for up to 20 years after collection. The OR increased to 3.8 (2.6-5.4) when the CRFs were added to the model. For fractures limited to 13 years after collection, the OR was 6.3 (3.0-13.1) for the score alone. The test based on Raman spectroscopy has potential for identifying individuals who may suffer hip fractures several years in advance. Higher powered studies are required to evaluate the predictive capability of this test.

    Neighborhood Self-Selection: The Role of Pre-Move Health Factors on the Built and Socioeconomic Environment
    (MDPI, 2015) James, Peter; Hart, Jaime; Arcaya, Mariana; Feskanich, Diane; Laden, Francine; Subramanian, S.V.
    Residential self-selection bias is a concern in studies of neighborhoods and health. This bias results from health behaviors predicting neighborhood choice. To quantify this bias, we examined associations between pre-move health factors (body mass index, walking, and total physical activity) and post-move neighborhood factors (County Sprawl Index, Census tract socioeconomic status (SES)) in the Nurses’ Health Study (n = 14,159 moves from 1986–2008). Individuals in the highest quartile of pre-move BMI (BMI > 28.4) compared to the lowest quartile (BMI < 22.5) moved to counties that averaged 2.57 points lower on the sprawl index (95% confidence interval −3.55, −1.59) indicating that individuals moved to less dense counties; however, no associations were observed for pre-move walking nor total physical activity. Individuals with higher pre-move BMI tended to move to Census tracts with lower median income and home values and higher levels of poverty. Analyses examining the change in neighborhood environments after a move demonstrated that healthy pre-move behaviors were associated with moves to worse socioeconomic environments. This type of self-selection would bias results downward, underestimating the true relationship between SES and physical activity. Generally, the magnitudes of associations between pre-move health factors and neighborhood measures were small and indicated that residential self-selection was not a major source of bias in analyses in this population.

    Use of Proton Pump Inhibitors and Risk of Hip Fracture in Relation to Dietary and Lifestyle Factors: A Prospective Cohort Study
    (BMJ Publishing Group, 2012) Khalili, Hamed; Huang, Edward S.; Jacobson, Brian C.; Camargo, Carlos; Feskanich, Diane; Chan, Andrew
    Objective: To examine the association between chronic use of proton pump inhibitors (PPIs) and risk of hip fracture. Design Prospective cohort study. Setting: Nurses’ Health Study, which originally recruited from the 11 most populous states in the US. Participants: 79 899 postmenopausal women enrolled in the Nurses’ Health Study who provided data on the use of PPIs and other risk factors biennially since 2000 and were followed up to 1 June 2008. Main outcome measure: Incident hip fracture Results: During 565 786 person years of follow-up, we documented 893 incident hip fractures. The absolute risk of hip fracture among regular users of PPIs was 2.02 events per 1000 person years, compared with 1.51 events per 1000 person years among non-users. Compared with non-users, the risk of hip fracture among women who regularly used PPIs for at least two years was 35% higher (age adjusted hazard ratio 1.35 (95% confidence interval 1.13 to 1.62)), with longer use associated with increasing risk (P\(_{trend}\)<0.01). Adjustment for risk factors, including body mass index, physical activity, and intake of calcium did not materially alter this association (hazard ratio 1.36 (1.13 to 1.63)). These associations were also not changed after accounting for reasons for PPI use. The relation between PPI use and fracture differed by smoking history (P\(_{interaction}\)=0.03). Among current and former smokers, PPI use was associated with greater than 50% increase in risk of fracture, with a multivariate hazard ratio for fracture of 1.51 (1.20 to 1.91). In contrast, among women who never smoked there was no association (multivariate hazard ratio 1.06 (0.77 to 1.46)). In a meta-analysis of these results with 10 prior studies, the pooled odds ratio of hip fracture associated with PPI use was 1.30 (1.25 to 1.36). Conclusion: Chronic use of PPIs is associated with increased risk of hip fracture, particularly among women with a history of smoking.

    Interactions between Plasma Levels of 25-Hydroxyvitamin D, Insulin-Like Growth Factor (IGF)-1 and C-Peptide with Risk of Colorectal Cancer
    (Public Library of Science, 2011) Wu, Kana; Feskanich, Diane; Fuchs, Charles; Chan, Andrew; Willett, Walter; Hollis, Bruce W.; Pollak, Michael N.; Giovannucci, Edward
    Background: Vitamin D status and levels of insulin-like growth factor (IGF)-1 and C-peptide have been implicated in colorectal carcinogenesis. However, in contrast to vitamin D IGF-1 is not an easily modifiable risk factor. Methods: Combining data from the Health Professionals Follow up Study (HPFS) and the Nurses' Health Study cohort (NHS) additive and multiplicative interactions were examined between plasma 25-hydroxyvitamin D (25(OH)D) and IGF-1, IGFBP-3 as well as C-peptide levels in 499 cases and 992 matched controls. For the various analytes, being high or low was based on being either above (or equal) or below the medians, respectively. Results: Compared to participants with high 25(OH)D and low IGF-1/IGFBP-3 ratio (reference group), participants with a high IGF-1/IGFBP-3 ratio were at elevated risk of colorectal cancer when 25(OH)D was low (odds ratio (OR): 2.05 (95% CI: 1.43 to 2.92), but not when 25(OH)D was high (OR:1.20 (95% CI: 0.84 to 1.71, p(interaction): additive = 0.06, multiplicative = 0.25). Similarly, compared to participants with high 25(OH)D and low molar IGF-1/IGFBP-3 ratio and low C-peptide levels (reference group), participants with a combination of either high IGF-1/IGFBP-3 ratio or high C-peptide were at elevated risk for colorectal cancer when 25(OH)D was low (OR = 1.90, 95% CI: 1.22 to 2.94) but not when 25(OH)D was high (OR = 1.15, 95% CI: 0.74 to 1.77, p(interaction): additive = 0.004; multiplicative = 0.04). Conclusion: The results from this study suggest that improving vitamin D status may help lower risk of colorectal cancer associated with higher IGF-1/IGFBP-3 ratio or C-peptide levels.

    Protein, iron, and meat consumption and risk for rheumatoid arthritis: a prospective cohort study
    (BioMed Central, 2007) Benito-Garcia, Elizabeth; Feskanich, Diane; Hu, Frank; Mandl, Lisa A; Karlson, Elizabeth
    A recent prospective study showed that higher consumption of red meat and total protein was associated with increased risk for inflammatory polyarthritis. We therefore prospectively examined the relationship between diet (in particular, protein, iron, and corresponding food sources) and incident rheumatoid arthritis (RA) among 82,063 women in the Nurses' Health Study. From 1980 to 2002, 546 incident cases of RA were confirmed by a connective tissue disease screening questionnaire and medical record review for American College of Rheumatology criteria for RA. Diet was assessed at baseline in 1980 and five additional times during follow up. We conducted Cox proportional hazards analyses to calculate the rate ratio of RA associated with intakes of protein (total, animal, and vegetable) and iron (total, dietary, from supplements, and heme iron) and their primary food sources, adjusting for age, smoking, body mass index, and reproductive factors. The multivariate models revealed no association between RA and any measure of protein or iron intake. In comparisons of highest with lowest quintiles of intake, the rate ratio for total protein was 1.17 (95% confidence interval 0.89–1.54; P for trend = 0.11) and for total iron it was 1.04 (95% confidence interval 0.77–1.41; P for trend = 0.82). Red meat, poultry, and fish were also not associated with RA risk. We were unable to confirm that there is an association between protein or meat and risk for RA in this large female cohort. Iron was also not associated with RA in this cohort.

    Lung cancer occurrence in never-smokers: an analysis of 13 cohorts and 22 cancer registry studies
    (Public Library of Science, 2008) Thun, Michael J; Hannan, Lindsay M; Adams-Campbell, Lucile L; Flanders, W. Dana; Jee, Sun Ha; Katanoda, Kota; Kolonel, Laurence N; Marugame, Tomomi; Palmer, Julie R; Riboli, Elio; Sobue, Tomotaka; Avila-Tang, Erika; Wilkens, Lynne R; Samet, Jon M; Bofetta, Paolo; Buring, Julie; Feskanich, Diane; Lee, I-Min
    Background: Better information on lung cancer occurrence in lifelong nonsmokers is needed to understand gender and racial disparities and to examine how factors other than active smoking influence risk in different time periods and geographic regions. Methods and Findings: We pooled information on lung cancer incidence and/or death rates among self-reported never-smokers from 13 large cohort studies, representing over 630,000 and 1.8 million persons for incidence and mortality, respectively. We also abstracted population-based data for women from 22 cancer registries and ten countries in time periods and geographic regions where few women smoked. Our main findings were: (1) Men had higher death rates from lung cancer than women in all age and racial groups studied; (2) male and female incidence rates were similar when standardized across all ages 40+ y, albeit with some variation by age; (3) African Americans and Asians living in Korea and Japan (but not in the US) had higher death rates from lung cancer than individuals of European descent; (4) no temporal trends were seen when comparing incidence and death rates among US women age 40–69 y during the 1930s to contemporary populations where few women smoke, or in temporal comparisons of never-smokers in two large American Cancer Society cohorts from 1959 to 2004; and (5) lung cancer incidence rates were higher and more variable among women in East Asia than in other geographic areas with low female smoking. Conclusions: These comprehensive analyses support claims that the death rate from lung cancer among never-smokers is higher in men than in women, and in African Americans and Asians residing in Asia than in individuals of European descent, but contradict assertions that risk is increasing or that women have a higher incidence rate than men. Further research is needed on the high and variable lung cancer rates among women in Pacific Rim countries.
