Age-Stratified Assessment of the Impact of Breast Cancer Knowledge on the Lifestyle and Dietary Patterns Among Nigerian Females.

Purpose: Breast cancer (BC) is a major cause of cancer-related mortality in Nigeria, which is exacerbated by a lack of understanding of how knowledge of BC risk factors influences the lifestyle and dietary patterns of Nigerians across age groups. This study evaluated the influence of knowledge of BC risks on lifestyle and dietary patterns across age groups, aiming to inform early management, prevention, and survival rates.

Methods: A cross-sectional survey was conducted in Ota, Ado-odo, Ogun State, Nigeria, involving participants from six educational institutions. The study assessed knowledge of BC risks factors and lifestyle/dietary habits using questionnaires. Results were analyzed using Epi Info software and SPSS version 20.

Results: The participants' age ranged from 13 to 60 years, with a mean of 21 years. The age categories of the participants were 75.24% adolescents (13-19), 18.68% young adults (20-40), and 6.08% middle-aged (41-60). Middle-aged individuals had the least knowledge about smoking (7.58%), alcohol (26.09%), antibiotics (7.25%), and red meat/smoked foods (20.09%), which translated into their poor dietary/lifestyle patterns. Young adults showed profound physical inactivity (71.00%), while adolescents consumed more carbonated drinks (71.53%), which corresponded to lack of knowledge about the effects of physical inactivity (10.85%) and consumption of carbonated drinks (13.70%) on BC risk.

Conclusion: The study found that understanding BC risk factors directly affects lifestyle and dietary patterns. Age groups with higher knowledge had better lifestyle/dietary patterns. This highlights the need for a tailored intervention on lifestyle and dietary education across all age groups, especially the middle-aged, so as to inform a deliberate adjustment in lifestyle and dietary habits, which play crucial roles in BC incidence, survival, and prevention.
