Obesity affects 18% of U.S. children. In a recent report, maternal consumption of ≥150 mg of caffeine per day during pregnancy was associated with increased odds for obesity in the offspring (odds ratio = 2.1 [95% confidence interval = 1.2-3.5]). If this association was causal, a considerable fraction of childhood obesity might be prevented by reduction of caffeine intake in pregnancy.
We studied 1986 mother-child pairs who were controls from a case-control study of caffeine metabolites and spontaneous abortion nested within the Collaborative Perinatal Project. Women were pregnant during 1959-1966, and children were followed with visits at 48 and/or 84 months of age, when height and weight were measured according to a standardized protocol. Serum was drawn at <20 and ≥26 weeks’ gestation and assayed for paraxanthine (caffeine‘s primary metabolite) by high-performance liquid chromatography. Relative risks of obesity (body mass index ≥95th percentile for age and sex) were estimated by log-binomial or Poisson regression and adjusted for maternal age, race, education, smoking, prepregnant weight, diabetes in pregnancy, and gestational age at blood draw.
Obesity prevalence was 11.7% at 48 months and 6.5% at 84 months. Associations of maternal serum paraxanthine and child obesity were nonlinear, and adjustment reduced the magnitude of all associations. The maximum relative risk (approximately 1.4) was for the association of paraxanthine drawn at <20 weeks with obesity at ages 48 and 84 months.
This study does not support an increased risk of childhood obesity with increasing maternal caffeine consumption during pregnancy.

Introduction: Specific coffee subtypes and tea may impact risk of pre- and post-menopausal breast cancer differently. We investigated the association between coffee (total, caffeinated, decaffeinated) and tea intake and risk of breast cancer.
Methods: A total of 335,060 women participating in the European Prospective Investigation into Nutrition and Cancer (EPIC) Study, completed a dietary questionnaire from 1992 to 2000, and were followed-up until 2010 for incidence of breast cancer. Hazard ratios (HR) of breast cancer by country-specific, as well as cohort-wide categories of beverage intake were estimated.
Results: During an average follow-up of 11 years, 1064 premenopausal, and 9134 postmenopausal breast cancers were diagnosed. Caffeinated coffee intake was associated with lower risk of postmenopausal breast cancer: adjusted HR¿=¿0.90, 95% confidence interval (CI): 0.82 to 0.98, for high versus low consumption; P trend = 0.029. While there was no significant effect modification by hormone receptor status (P = 0.711), linear trend for lower risk of breast cancer with increasing caffeinated coffee intake was clearest for estrogen and progesterone receptor negative (ER-PR-), postmenopausal breast cancer (P = 0.008). For every 100 ml increase in caffeinated coffee intake, the risk of ER-PR- breast cancer was lower by 4% (adjusted HR: 0.96, 95% CI: 0.93 to 1.00). Non-consumers of decaffeinated coffee had lower risk of postmenopausal breast cancer (adjusted HR = 0.89; 95% CI: 0.80 to 0.99) compared to low consumers, without evidence of dose-response relationship (P trend = 0.128). Exclusive decaffeinated coffee consumption was not related to postmenopausal breast cancer risk, compared to any decaffeinated-low caffeinated intake (adjusted HR = 0.97; 95% CI: 0.82 to 1.14), or to no intake of any coffee (HR: 0.96; 95%: 0.82 to 1.14). Caffeinated and decaffeinated coffee were not associated with premenopausal breast cancer. Tea intake was neither associated with pre- nor post-menopausal breast cancer.
Conclusions: Higher caffeinated coffee intake may be associated with lower risk of postmenopausal breast cancer. Decaffeinated coffee intake does not seem to be associated with breast cancer.

Background: Epidemiological studies that have investigated the association between coffee, tea and caffeine consumption and ovarian cancer risk have produced conflicting results. Furthermore, only few studies have examined the role of coffee and tea consumption separately for borderline ovarian tumors. By use of data from a large Danish population based case-control study, we examined the risk of ovarian tumors associated with coffee, tea, and caffeine consumption with a particular focus on characterizing risks by tumor behavior and histology.
Material and methods: From 1995 through 1999, we included 267 women with ovarian cancer, 115 women with borderline ovarian tumors and 911 randomly selected control women. All women completed a beverage frequency questionnaire with detailed information on coffee and tea consumption. Analyses were performed using multiple logistic regression models.
Results: Both coffee (OR 0.90; 95% CI 0.84 – 0.97 per cup/day) and total caffeine consumption from coffee and tea combined (OR 0.93; 95% CI 0.88 – 0.98 per 100 mg/day) decreased the risk of ovarian cancer. These associations were significant only for the serous and “ other ” subtypes of ovarian cancer. No relation between tea consumption and ovarian cancer risk was observed. The risk estimates for borderline ovarian tumors resembled those observed for ovarian cancer, but did not reach statistical significance.
Conclusions: Our results indicate that coffee consumption and total caffeine consumption from coffee and tea combined is associated with a modest decreased risk of ovarian cancer. However, more biological studies are needed to identify bioactive chemical compounds in coffee that potentially could affect ovarian cancer development.

OBJECTIVE: To evaluate the effect of caffeine on balance control of hemiparetic stroke patients, we investigated the difference in postural stability before and after drinking coffee by observing changes in stability index (SI) from posturography.
METHODS: Thirty patients with history of stroke and 15 age-matched healthy subjects participated in this study. Effect of group factor (of the control and stroke groups) and treatment factor (pre- and post-drinking of coffee) on SI were tested in three conditions: with eyes opened, with eyes closed, and with a pillow support. The effects of these factors on visual deprivation and somatosensory change of subjects were also tested.
RESULTS: Under all conditions, SI was higher in the stroke group than in the control group. Under eyes-open condition, the treatment factor was not statistically significant. Under eyes-closed condition, the interaction between group and treatment factor was statistically significant. After the subjects drank coffee, SI in the control group was increased. However, SI in the stroke group was decreased. Under pillow-supported condition, the interaction between group and treatment factor appeared marginally significant. For visual deprivation effect, the interaction between treatment and group factor was statistically significant. After caffeine consumption, the visual deprivation effect was increased in control group but decreased in the stroke group. For somatosensory change effect, the interaction between group and treatment factor was not statistically significant.
CONCLUSION: Postural stability of hemiparetic stroke patients related to somatosensory information was improved after intake of usual dose of caffeine.
