“…Indeed, the women in our study display sociodemographic and lifestyle characteristics similar to those seen in the Spanish National Health Survey. 58 In conclusion, our results show that higher calorie intake is associated with higher MD, a finding in line with the results obtained by other studies. Furthermore, high consumption of olive oil decreases the prevalence of high MD, and our study thus supports the protective role of olive oil vis-a-vis breast cancer.…”

High mammographic density (MD) is one of the main risk factors for development of breast cancer. To date, however, relatively few studies have evaluated the association between MD and diet. In this cross-sectional study, we assessed the association between MD (measured using Boyd's semiquantitative scale with five categories: <10%, 10–25%, 25–50%, 50–75% and >75%) and diet (measured using a food frequency questionnaire validated in a Spanish population) among 3,548 peri- and postmenopausal women drawn from seven breast cancer screening programs in Spain. Multivariate ordinal logistic regression models, adjusted for age, body mass index (BMI), energy intake and protein consumption as well as other confounders, showed an association between greater calorie intake and greater MD [odds ratio (OR) = 1.23; 95% confidence interval (CI) = 1.10-1.38, for every increase of 500 cal/day], yet high consumption of olive oil was nevertheless found to reduce the prevalence of high MD (OR = 0.86;95% CI = 0.76-0.96, for every increase of 22 g/day in olive oil consumption); and, while greater intake of whole milk was likewise associated with higher MD (OR = 1.10; 95%CI 1.00-1.20, for every increase of 200 g/day), higher consumption of protein (OR = 0.89; 95% CI 0.80-1.00, for every increase of 30 g/day) and white meat (p for trend 0.041) was found to be inversely associated with MD. Our study, the largest to date to assess the association between diet and MD, suggests that MD is associated with modifiable dietary factors, such as calorie intake and olive oil consumption. These foods could thus modulate the prevalence of high MD, and important risk marker for breast cancer.

“…According to previous studies (Rajmil L et al 2013;García-Arenzana et al 2012), the negative effects of the economic crisis appear to be mostly localized on those people with relatively less education of secondary school degree or less. These people, in general, were dependent on the manufacturing sector for employment, where the absolute number of manufacturing jobs has declined in crisis times.…”

The objective was to investigate how socio-economic changes have modified body mass index values and dietary patterns in the Spanish population. A comparative cross-sectional analysis of the last two iterations of the Spanish National Health Survey (SNSH) was done. The independent variables were sex, age, education level, employment situation, and social class. Outcome variables were: poor diet quality and obesity. Economic crisis increases the probability to become obese and to have a poor diet and employment situation is the variable that showed the greatest differences between years. While in 2006 to be unemployed did not represent a risk to have a poor diet [odds ratio (OR): 0.74; p<.005], in 2012 it did (OR: 1.27; p<.005). Economic changes can modify diet quality and nutritional status, increasing the risk to have a poor diet or to be obese.

“…Our participants seem to be representative of the entire Spanish female population of the same age range. 41 Finally, the two-stage design using extreme phenotypes in the first stage has shown to be a cost-efficient strategy for identification of new genetic variants. 42 The measurement of density was performed visually by a single radiologist using categorical scales and might be considered a limitation.…”

Mammographic density (MD) is an intermediate phenotype for breast cancer. Previous studies have identified genetic variants associated with MD; however, much of the genetic contribution to MD is unexplained. We conducted a two-stage genomewide association analysis among the participants in the "Determinants of Density in Mammographies in Spain" study, together with a replication analysis in women from the Australian MD Twins and Sisters Study. Our discovery set covered a total of 3,351 Caucasian women aged 45 to 68 years, recruited from Spanish breast cancer screening centres. MD was blindly assessed by a single reader using Boyd's scale. A two-stage approach was employed, including a feature selection phase exploring 575,374 SNPs in 239 pairs of women with extreme phenotypes and a verification stage for the 183 selected SNPs in the remaining sample (2,873 women). Replication was conducted in 1,786 women aged 40 to 70 years old recruited via the Australian Twin Registry, where MD were measured using Cumulus-3.0, assessing 14 SNPs with a p value <0.10 in stage 2.

Diet quality and related factors among Spanish female participants in breast cancer screening programs

Abstract: The youngest women, the most sedentary women, and those who had a lower educational level and socioeconomic status registered worse diet quality. Ex-smokers and postmenopausal women obtained better scores, probably reflecting a keener concern about leading a healthy life.
