“…13 The present findings indicate menarche age also relates to mammography history, with previous mammograms more likely in women of a younger menarche age. Again, this arguably depicts efforts by health providers to increase breast cancer awareness or deliberate efforts by the women themselves to seek mammography (given their elevated risk) in response to the health promotion jingles.…”

“…12 Research also suggests age at menarche is critical in Nigerian women with younger age at first menstruation being associated with elevated breast cancer risk. 8,13 Finally, age at menopause has also been implicated in breast cancer risk, with older age at menopause being associated with greater risk. 14 Given the early onset of breast cancer in African women, there is a need to better understand the link between age-related risk factors and mammography uptake in this population.…”

BackgroundBreast cancer accounts for 25% of diagnosed cancers and 20% of cancer-related mortality amongst women in sub-Saharan Africa. 1 Data from the International Agency for Research on Cancer suggest about 100 000 breast cancer cases are diagnosed annually in the African region, with the largest number of country-specific cases diagnosed in Nigeria (circa 14 000) yearly. 2 While the breast cancer incidence and mortality rates remain highest in fully industrialised nations, rates are rapidly increasing in developing countries. Thus, there is a dire need to detect cancer early, when it is more responsive to treatment. 3 Mammography is a breast imaging method that employs low-dose x-rays to detect cancer early, thereby reducing the incidence of advanced cancers with poor prognosis. 3 Mammography screening in Nigeria is offered to women aged from 40 to 70 years, 4 although women under 40 years may also be invited for mammograms if they have a strong family history of breast cancer. 5 The efficacy of mammography in younger women is debatable (because of higher breast density). 6 Nevertheless, missing a mammogram can significantly increase the likelihood of being diagnosed with cancer at a later stage. 7Background: Breast cancer accounts for 25% of diagnosed cancers and 20% of cancer-related mortality in women from sub-Saharan Africa. Given the early onset of breast cancer in African women, there is a need to better understand how age-related risk factors contribute to mammography uptake in this population.

“…Em um estudo caso-controle desenvolvido na Nigéria com uma amostra de 819 casos e 569 controles, pesquisadores encontraram uma redução de 7% no risco de desenvolver esse tipo de câncer a cada aumento de 12 meses no tempo de amamentação (OR=0,93; IC95% 0,87-1,0) 11 . Uma possível explicação para esse fato é que durante a amamentação ocorrem períodos de baixa exposição ao estrógeno e tal hormônio está intimamente envolvido na carcinogênese da doença 12 .…”

RESUMOObjetivo: Mediante o impacto na saúde pública e a importância da neoplasia de mama para a saúde da mulher, o objetivo deste estudo foi verificar os fatores de risco, os dados demográficos e os achados ao exame físico e aos exames complementares de uma população de pacientes em acompanhamento por câncer de mama em um hospital de Fortaleza. Métodos: Foi realizado um estudo transversal observacional, descritivo e retrospectivo de base hospitalar. Os dados foram coletados por meio de um instrumento de coleta de informação. As variáveis incluíram: idade, menarca, paridade, idade do primeiro parto, terapia hormonal, amamentação, história familiar, tabagismo, etilismo, achados ao exame físico, exames complementares de imagem e histopatológico. Foi analisada a classificação BI-RADS dos exames de imagem. Resultados: A mediana de idade foi 55 anos. Dentre os fatores de risco, a menarca variou de 9 a 18 anos de idade. 70,0% das mulheres possuíam até 4 filhos, com história de amamentação em 86,7%. O fator terapia hormonal estava presente em 20,3% (11/54), com duração entre 1 e 10 anos; o tabagismo, em 32,7% (18/55). 36,8% (25/68) apresentavam história familiar de neoplasia de mama. Analisando o resultado da primeira mamografia do acompanhamento, identificamos que 28,5% (14/49) apresentaram BI-RADS 0, e 59,2% (29/49), BI-RADS de 4 a 6. Conclusão: O impacto global do câncer de mama em mulheres é considerável e crescente em muitos países. Uma adequada caracterização das populações acometidas auxilia os profissionais de saúde, melhorando seu grau de suspeição e contribuindo para o diagnóstico precoce.

“…Women in the lowest socioeconomic groups were the most likely to breastfeed exclusively likely due to cultural factors that incentivize breastfeeding and financial constrains that limit access to infant formula (Huo et al, 2008;Smith-Oka, 2009). Prior studies in Colombia found that woman with higher levels of education were more likely to stop exclusive breastfeeding and introduce artificial infant formula due to the constraints of maternal leave and the need to return to the workplace (Niño, 2014).…”

Objective: The aim of this study was to analyze trends in infant breastfeeding and artificial infant milk consumption in Ecuador from 2007 to 2014. Methods:This descriptive observational study includes all the available data collected and adapted from the National Health and Nutrition Survey of Ecuador, ENSANUT, the Ecuadorian National Institute of Census and Statistics, the national report of the International Marketing Services and data from Enfarma EP. Descriptive and inferential statistics were used to determine sociodemographic distribution and temporal trends. Results:In Ecuador 54% of children initiate breastfeeding during the first hour of life, and 43% of children aged five months are breastfed exclusively. 76% of children under one month of age and 60% of children under six months consume artificial infant formula. Over the last 8 years infant formula consumption has tripled in Ecuador reaching 59.6 million units sold at a cost of $530,100,000 USD from 2007 to 2014. Conclusions:Breastfeeding practices in Ecuador are not complying with WHO recommendations and infant milk formulas consumption has risen significantly since 2007, despite active campaigns by the public health sector to educate women as to the benefits of breastfeeding.
