“…Caffeine intake also presented a result lower than the findings of Boggs et al 43 in a prospective cohort study in which the median intake was 312 mg/day, while in our findings, this intake was 108.11 mg/day. In a study conducted in Brazil among both white and black men, higher calcium intake was found in whites (720 ± 346 versus 558 ± 236 mg), but there was only a correlation with the bone mineral density of the femoral neck among blacks.…”

CONTEXT AND OBJECTIVE: Osteoporosis is a skeletal abnormality characterized by reduction and alteration of bone microarchitecture that results in increased fragility and greater predisposition to fractures. Age and low bone mass are the main non-modifiable risk factors for osteoporotic fractures. The modifiable factors include sedentary lifestyle, inadequate calcium intake, excessive alcohol and/or caffeine consumption, smoking and low body weight. The aim here was to evaluate the association between low bone mass and calcium and caffeine intake among perimenopausal women in Southern Brazil. DESIGN AND SETTING: Cross-sectional study conducted in Porto Alegre and Canoas, Rio Grande do Sul, Brazil. METHODS: Women (n = 155) of mean age 53.6 ± 9.5 years were evaluated through a cross-sectional study in Southern Brazil. Food frequency questionnaires, bone mass evaluation using calcaneal ultrasound and anthropometric assessment were used. RESULTS: The prevalence of overweight was 67.7%. In the bone mass screening, 30.3% had low bone mass and 4.5% had osteoporosis. The median calcium intake was 574.94 mg/day and the caffeine intake was 108.11 mg/day. No association was found between bone mass and anthropometric parameters, calcium intake or caffeine intake. It was found that 38.4% of the women had low bone mass. CONCLUSIONS: No association was found between calcium and caffeine intake and bone mass. High prevalence of low bone mass was observed. RESUMO CONTEXTO E OBJETIVO:A osteoporose é uma alteração esquelética caracterizada pela redução e pela alteração da microarquitetura óssea, que resultam em aumento da fragilidade e maior predisposição a fraturas. A idade e a baixa massa óssea são os principais fatores de risco não modificáveis para fraturas osteoporóticas. Os fatores modificáveis incluem sedentarismo, inadequada ingestão de cálcio, excessivo consumo de álcool e/ou cafeína, tabagismo e baixo peso corporal. O objetivo foi avaliar associação entre baixa massa óssea e ingestão de cálcio e cafeína por mulheres climatéricas no Sul do Brasil. TIPO DE ESTUDO E LOCAL: Estudo transversal realizado em Porto Alegre e Canoas, Rio Grande do Sul, Brasil. MÉTODOS: Mulheres (n = 155) com idade média de 53,6 ± 9,5 anos foram avaliadas em um estudo transversal na região Sul do Brasil. Foram utilizados questionários de frequência alimentar, avaliação da massa óssea por ultrassonometria de calcâneo e avaliação antropométrica. RESULTADOS: A prevalência de sobrepeso foi de 67,7%. No rastreamento de massa óssea, 30,3% apresentou baixa massa óssea e 4,5%, osteoporose. A ingestão mediana de cálcio foi de 574,94 mg/dia e de cafeína foi de 108,11 mg/dia. Não foi encontrada associação entre massa óssea e os parâmetros antropométricos, ingestão de cálcio ou de cafeína. Verificou-se que 38,4% das mulheres apresentaram perda de massa óssea. CONCLUSÕES: Não foi encontrada associação entre a ingestão de cálcio e cafeína com a massa óssea. Foi observada alta prevalência de baixa massa óssea.

“…Additionally, our population primarily comprised white women, and our findings may not be generalizable to other racial/ethnic groups. However, although the prevalence of risk factors often differs across population subgroups, many breast cancer risk factors have been documented to operate across racial/ethnic groups, as would be expected from diseases with a common underlying biology (20,(40)(41)(42)(43)(44)(45)(46)(47)(48)(49)(50)(51)(52). Although we included family history as a nonmodifiable risk factor, we did not directly test for inherited mutations in genes that increase the risk of breast cancer; these are more common causes of breast cancer in younger, premenopausal women (53).…”

We examined the proportions of multiple types of breast cancers in the population that were attributable to established risk factors, focusing on behaviors that are modifiable at menopause. We estimated the full and partial population attributable risk percentages (PAR%) by combining the relative risks and the observed prevalence rates of the risk factors of interest. A total of 8,421 cases of invasive breast cancer developed in postmenopausal women (n = 121,700) in the Nurses' Health Study from 1980-2010. We included the following modifiable risk factors in our analyses: weight change since age 18 years, alcohol consumption, physical activity level, breastfeeding, and menopausal hormone therapy use. Additionally, the following nonmodifiable factors were included: age, age at menarche, height, a combination of parity and age at first birth, body mass index at age 18 years, family history of breast cancer, and prior benign breast disease. When we considered all risk factors (and controlled for age), the PAR% for invasive breast cancers was 70.0% (95% confidence interval: 55.0, 80.7). When considering only modifiable factors, we found that changing the risk factor profile to the lowest weight gain, no alcohol consumption, high physical activity level, breastfeeding, and no menopausal hormone therapy use was associated with a PAR% of 34.6% (95% confidence interval: 22.7, 45.4). The PAR% for modifiable factors was higher for estrogen receptorpositive breast cancers (PAR% = 39.7%) than for estrogen receptor-negative breast cancers (PAR% = 27.9%). Risk factors that are modifiable at menopause account for more than one-third of postmenopausal breast cancers; therefore, a substantial proportion of breast cancer in the United States is preventable. modifiable factors; PAR%; postmenopausal breast cancer Abbreviations: BMI, body mass index; CI, confidence interval; ER, estrogen receptor; ER−, estrogen receptor-negative; ER+, estrogen receptor-positive; MHT, menopausal hormone therapy; PAR%, population attributable risk percentage; RR, relative risk.Breast cancer is the most common cancer among women in the United States, and it is a major cause of morbidity and mortality globally. It has been estimated that 232,340 cases of invasive breast cancer and 39,620 breast cancer deaths occur annually in the United States (1). A nearly 5-fold difference in breast cancer incidence rates exists among countries globally (2). This geographic variability in incidence rates for breast cancer suggests that differences in the prevalence rates of risk factors among countries are associated with variation in breast cancer rates. Additionally, in migration studies, incidence rates of breast cancer among the descendants of women who moved from low-incidence countries to high-incidence countries converged to those of the high-incidence countries (3-7), which suggests that modifiable lifestyle factors account for much of the global difference in incidence rates. Thus, identification of modifiable risk factors for breast cancer has important impl...

“…35 Conversely, the HANDLS African American population was about three times below the national average. In a study by Boggs et al, 36 it was noted that African American females drink less tea and coffee than their white counterparts do. When expressed as caffeine (in mg) per kilogram of body weight, the caffeine intake of the African Americans was lower than that reported by Mitchell et al…”

Background: Recent research has linked caffeine consumption with a lower risk for depression and cognitive decline. However, no studies have examined the relationship in an African American compared to a white, socioeconomically diverse representative urban sample. Methods: Data from a cross-sectional study were used to determine the associations of caffeine use with depressive symptomatology and cognition in a sample of 1,724 participants in the Healthy Aging in Neighborhoods of Diversity across the Life Span (HANDLS) study. The United States Department of Agriculture's Automated Multiple Pass Method was used by trained interviewers to collect two, in-person 24-hour dietary recalls. Depressive symptoms and global cognition were assessed using two well-validated measures: the Center for Epidemiologic Studies Depressive Scale (CES-D) and Mini Mental State Examination (MMSE), respectively. Usual caffeine intake was based on both recalls. Data were analyzed with t-and chi-square tests, correlation analysis, and ordinal logistic regression. Results: African Americans consumed significantly less caffeine than did whites (89.0 -3.2 and 244.0 -8.7 mg respectively). Caffeine consumption was not associated with depressive symptomatology or global cognition. Age, less than 5th grade literacy, and less than high school education were significantly associated with both depressive symptoms and cognitive function. Smokers had a 43% greater risk for depression but only a 3% higher risk for cognitive impairment. Conclusion: The low level of dietary caffeine intake in combination with smoking among HANDLS study participants may have influenced the lack of association with depressive symptomatology or global cognition. For this sample, low literacy and education appear more highly associated with depressive symptoms and cognitive function than caffeine intake.
