“…These data are not consistent with the epidemiological evidence that birth weight increases with birth order, and the correlation of birth weight and breast cancer risk (Trichopoulos, 1990;Michels et al, 1996;Sanderson et al, 1996;Juntunen et al, 1997;Andersson et al, 2000;Kaijser et al, 2000). No association was found between the number of siblings and male breast cancer (Petridou et al, 2000;Sorensen et al, 2005). The strong inverse association between the Sibship size and solid tumours A Altieri and K Hemminki number of siblings and the risk of endometrial cancer, consistent across strata of age, has never been reported before.…”

“…For example, birth order has been associated with birth weight, a risk factor for breast cancer (Juntunen et al, 1997;Potischman and Troisi, 1999;Barba et al, 2006). In utero estradiol levels decrease with birth order, with potential implications for risks of breast, testicular and possibly other cancer sites (Bernstein et al, 1986;Panagiotopoulou et al, 1990;Trichopoulos, 1990;Hsieh et al, 1991;Prener et al, 1992;Westergaard et al, 1998;Potischman and Troisi, 1999;Petridou et al, 2000;Weir et al, 2000;Hodgson et al, 2004;Richiardi et al, 2004;Sorensen et al, 2005). Family crowding necessarily involves intimate contacts between its members, with potential effects on infectious diseases (Kinlen et al, 1990;Altieri et al, 2006a, b).…”

We analysed the effects of number of siblings on the risk of solid tumours using the Swedish Family-Cancer Database, including population-based information on over 11 million individuals and more than 178 000 cancer patients diagnosed between 1958 and 2004. Incidence rate ratios (RRs), estimated by Poisson regression models, were adjusted for age, sex, birth cohort, area of residence and socioeconomic status. Having eight or more siblings vs none increased the risk of stomach cancer (RR ¼ 1.83, 95% confidence interval (CI), 1.44 -2.34). Anal cancer diagnosed before age 40 showed the strongest association with the total siblings (RR ¼ 3.27, 95% CI, 2.04 -5.26 for five or more siblings vs none). Endometrial (RR ¼ 0.76, 95% CI, 0.70 -0.82), testicular (RR ¼ 0.71, 95% CI, 0.62 -0.82), skin cancer (RR ¼ 0.82, 95% CI, 0.69 -0.97) and melanoma (RR ¼ 0.72, 95% CI, 0.65 -0.79) showed strong decreased risks for five or more siblings vs none. Prostate cancer risk for those with five or more older siblings vs none was 1.38 (95% CI, 1.23 -1.55). Having five or more younger siblings was most strongly associated with stomach cancer (RR ¼ 1.59, 95% CI, 1.29 -1.95) and melanoma (RR ¼ 0.68, 95% CI, 0.59 -0.79). We conclude that sibship characteristics are strong correlates of cancer risk at several sites; plausible interpretations include socioeconomic status.

“…In brief, 11 case-control studies (5, 6, 12, 14, 15, 17, 21, 23-26) collectively contributed 1,190 cases and 4,531 controls, and 10 cohort studies (7, 8, 27-34) collectively contributed 1,215 cases and 47,482 controls. Combined, this provided a total of 2,405 male breast cancers and 52,013 controls for analysis.…”

Although two case-control studies (16, 22) could not be included because data were no longer available, we secured the contribution of data from 11 case-control (5, 6, 12, 14, 15, 17, 21, 23-26) and 10 cohort (7, 8, 27-34) investigations.

Background The etiology of male breast cancer is poorly understood, partly due to its relative rarity. Although tobacco and alcohol exposures are known carcinogens, their association with male breast cancer risk remains ill-defined. Methods The Male Breast Cancer Pooling Project consortium provided 2,378 cases and 51,959 controls for analysis from 10 case-control and 10 cohort studies. Individual participant data were harmonized and pooled. Unconditional logistic regression was used to estimate study design-specific (case-control/cohort) odds ratios (OR) and 95% confidence intervals (CI), which were then combined using fixed effects meta-analysis. Results Cigarette smoking status, smoking pack-years, duration, intensity, and age at initiation were not associated with male breast cancer risk. Relations with cigar and pipe smoking, tobacco chewing, and snuff use were also null. Recent alcohol consumption and average grams of alcohol consumed per day were also not associated with risk; only one sub-analysis of very high recent alcohol consumption (>60 grams/day) was tentatively associated with male breast cancer (ORunexposed referent=1.29, 95%CI:0.97–1.71; OR>0–<7 g/day referent=1.36, 95%CI:1.04–1.77). Specific alcoholic beverage types were not associated with male breast cancer. Relations were not altered when stratified by age or body mass index. Conclusions In this analysis of the Male Breast Cancer Pooling Project we found little evidence that tobacco and alcohol exposures were associated with risk of male breast cancer. Impact Tobacco and alcohol do not appear to be carcinogenic for male breast cancer. Future studies should aim to assess these exposures in relation to subtypes of male breast cancer.

“…There is also a growing body of research demonstrating that sexual expression may have health benefits for improving quality of life, self-esteem, reducing stress, depression, and suicide [2] . Some studies even suggest that sexual activity may be associated with reducing the risk of heart disease and cancer, the two leading causes of death in the United States of America [3][4] .…”

Abstract:Research aimed at investigating sexual behavior and assessing intervention to improve sexual and reproductive health among young adults in Jamaica has increased in recent decades. This study was carried out to assess both positive and negative sexual outcomes e.g. sexual activity and sexual satisfaction related to sexual behavior such as multiple partners and the use or non-use of condoms among young adults. As part of the Reproductive Health Survey, data on the socio-demographic characteristics, sexual activity and behavior were assessed using a 56-item questionnaire on 213 randomly selected young adults from the 14 parishes in Jamaica attending two major public hospitals. The majority of the respondents had their first sexual experience when they were 15-18 years old. Among the men, the majority achieved full sexual satisfaction (100.0%) and had sex daily (49.6%). The majority of women were unable to achieve full sexual satisfaction (69.3%, χ 2 =138.85, p< 0.05) yet had sexual intercourse more than once per week (76.1%, χ 2 = 58.05, p< 0.05). The majority of respondents had 2-3 sexual partners (51.2%), used condoms (56.7%) and ranked highest among those with sexually transmitted infections (85.9%). Comprehensive behavioural interventions should target these young adults who are engaged in high sexual risk behaviors.
