A total of 308,036 women were selected from the European Prospective Investigation into Cancer and Nutrition (EPIC) study to evaluate the association between tobacco smoking and the risk of cervical intraepithelial neoplasia of grade 3 (CIN3)/carcinoma in situ (CIS) and invasive cervical cancer (ICC). At baseline, participants completed a questionnaire and provided blood samples. During a mean follow‐up time of 9 years, 261 ICC cases and 804 CIN3/CIS cases were reported. In a nested case–control study, the baseline sera from 609 cases and 1,218 matched controls were tested for L1 antibodies against HPV types 11, 16, 18, 31, 33, 35, 45, 52, 58, and antibodies against Chlamydia trachomatis (CT), and Human Herpes Virus 2 (HHV‐2). Cervical samples were not available for HPV‐DNA analysis in this study. Multivariate analyses were used to estimate associations between smoking and risk of CIN3/CIS and ICC in the cohort and the case–control studies. In the cohort analyses smoking status, duration and intensity showed a two‐fold increased risk of CIN3/CIS and ICC, while time since quitting was associated with a two‐fold reduced risk. In the nested case–control study, consistent associations were observed after adjustment for HPV, CT and HHV‐2 serostatus, in both HPV seronegative and seropositive women. Results from this large prospective study confirm the role of tobacco smoking as an important risk factor for both CIN3/CIS and ICC, even after taking into account HPV exposure as determined by HPV serology. The strong beneficial effect of quitting smoking is an important finding that will further support public health policies for smoking cessation.

The association between vitamin D status and hepatocellular carcinoma (HCC) has not been well investigated, despite experimental evidence supporting an important role of vitamin D in liver pathophysiology. Our objective was to investigate the association between prediagnostic circulating 25-hydroxyvitamin D [25(OH)D] serum levels and the risk of HCC in a prospective, nested case-control study among 520,000 participants in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort. Each case (n 5 138) diagnosed between 1992 and 2010 was matched to one control by age, sex, study center, date and time of blood collection, and fasting status. Serum baseline levels of 25(OH)D were measured by liquid chromatography/tandem mass spectrometry. Multivariable incident rate ratios (IRRs) of HCC associated with continuous (per 10 nmol/L) or categorical levels (tertiles or a priori-defined categories) of prediagnostic 25(OH)D were calculated using conditional logistic regression. Higher 25(OH)D levels were associated with a 49% reduction in the risk of HCC (highest versus lowest tertile: multivariable IRR 5 0.51, 95% confidence interval [CI], 0.26 to 0.99; P trend 5 0.04; per 10 nmol/L increase: IRR 5 0.80, 95% CI, 0.68-0.94). The finding did not vary substantially by time from enrolment to diagnosis, and did not change after adjustment for biomarkers of preexisting liver damage, nor chronic infection with hepatitis B or C viruses. The findings were not modified by body size or smoking status. Conclusion: In this prospective study on western European populations, serum levels of 25(OH)D were inversely associated with the risk of HCC. Given the rising incidence of this cancer in low-risk developed countries and the strong public health interest surrounding the potentially cancer-protective roles of vitamin D, additional studies in different populations are required.

SRH provides a quick and simple tool for assessing health and identifying groups of elders at risk of early mortality that may be useful also in clinical settings. Modifying determinants of favourably rating health, e.g. by increasing physical activity and/or by eliminating obesity, may be important for older adults to "feel healthy" and "be healthy".

using data from the European Prospective Investigation into Cancer and Nutrition cohort of 477,206 participants from 10 European countries. Methods After 11.4 years of follow-up, 191 HCC, 66 IHBC and 236 GBTC cases were identified. Hazard ratios and 95 % confidence intervals (HR; 95 % CI) were estimated with Cox regression models with multivariable adjustment (baseline total energy intake, alcohol consumption and intake pattern, body mass index, physical activity, AbstractPurpose The aim of the study was to assess associations between intake of combined soft drinks (sugar sweetened and artificially sweetened) and fruit and vegetable juices and the risk of hepatocellular carcinoma (HCC), intrahepatic bile duct (IHBC) and biliary tract cancers (GBTC) Results No risk associations were observed for IHBC or GBTC. Combined soft drinks consumption of >6 servings/ week was positively associated with HCC risk: HR 1.83; 95 % CI 1.11-3.02, p trend = 0.01 versus non-consumers. In sub-group analyses available for 91 % of the cohort artificially sweetened soft drinks increased HCC risk by 6 % per 1 serving increment (HR 1.06, 95 % CI 1.03-1.09, n cases = 101); for sugar-sweetened soft drinks, this association was null (HR 1.00, 95 % CI 0.95-1.06; n cases = 127, p heterogeneity = 0.07). Juice consumption was not associated with HCC risk, except at very low intakes (<1 serving/week: HR 0.60; 95 % CI 0.38-0.95; p trend = 0.02 vs. non-consumers). Conclusions Daily intake of combined soft drinks is positively associated with HCC, but a differential association between sugar and artificially sweetened cannot be discounted. This study provides some insight into possible associations of HCC with sugary drinks intake. Further exploration in other settings is required.

67Objective: There is uncertainty about the direction and magnitude of the associations between parity, breastfeeding and the 68 risk of coronary heart disease (CHD). We examined the separate and combined associations of parity and breastfeeding 69 practices with the incidence of CHD later in life among women in a large pan-European cohort study. 70Methods: Data were used from EPIC-CVD, a case-cohort study nested within the EPIC prospective study of 520,000 71 participants from 10 countries. Information on reproductive history was available for 14,917 women, including 5,138 incident 72 cases of CHD. Using Prentice-weighted Cox regression separately for each country followed by random-effects meta-analysis, 73we calculated hazard ratios (HRs) and 95% confidence intervals (CIs) for CHD, after adjustment for age, study centre, and 74 several socioeconomic and biological risk factors. Key messages 86What is already known about this subject? 87 -Pregnancy poses a substantial challenge to the cardiovascular system of the mother and breastfeeding has been 88 suggested to reverse some of the pro-atherogenic changes. 89 -The direction and magnitude of the associations between parity, breastfeeding, and their combined effects, and the 90 risk of coronary heart disease (CHD) are uncertain. 91 92What does this study add? 93 -Compared with nulliparous women, parous women were at 20% increased risk of CHD and the excess risk was higher 94 with increasing number of children. 95 -Breastfeeding was associated with a 30% lower risk of CHD, compared with parous women who did not breastfeed. 96 -Compared with nulliparous women, childbearing was more strongly associated with a higher risk of CHD among 97 women who had never breastfed. This is despite the higher number of children among women who had ever 98
