According to Gram Research analysis, middle-aged and older women in lower-income areas fall into four distinct groups based on their health knowledge, with nearly half showing mixed strengths and challenges in understanding heart disease prevention. A 2026 cross-sectional study of 156 women in Florence found that those with less education and financial difficulty struggled significantly more to understand health information and were less likely to follow heart-healthy diets, suggesting doctors need to tailor prevention strategies to each woman’s specific knowledge gaps rather than using one-size-fits-all approaches.
A new study from Florence, Italy looked at how well middle-aged and older women understand health information and how that affects their heart health. Researchers found that women going through or past menopause in poorer neighborhoods face different challenges when trying to learn about preventing heart disease. By identifying four different groups based on how well women understand health information, doctors can now create better, more personalized programs to help these women protect their hearts. The study shows that women with less education and money often struggle more to understand health advice, which could widen the gap in heart disease prevention.
Key Statistics
A 2026 cross-sectional study of 156 perimenopausal and postmenopausal women in Florence, Italy identified four distinct health literacy profiles, with 48.7% showing mixed strengths and selective challenges in understanding health information.
Women in health literacy groups with more challenges were significantly less likely to follow a Mediterranean diet and reported lower nutrition literacy compared to women with stronger health knowledge profiles.
Among women in the study, those with stronger health literacy profiles reported higher sense of meaningfulness in life (p<0.001), suggesting that health knowledge may contribute to overall well-being beyond just disease prevention.
The smallest health literacy group (8.3% of women) faced widespread challenges across all measured domains of health understanding, highlighting the need for intensive, personalized support for the most vulnerable women.
The Quick Take
- What they studied: How well middle-aged and older women understand health information and whether this affects their ability to prevent heart disease
- Who participated: 156 women aged 45-70 living in a lower-income neighborhood in Florence, Italy who were going through or past menopause
- Key finding: Researchers found four different groups of women based on their health knowledge. Women with less education and money struggled more to understand health information and were less likely to eat healthy Mediterranean diets
- What it means for you: If you’re a middle-aged or older woman, especially in a lower-income area, doctors may need to explain heart disease prevention in simpler, more personalized ways. This research suggests one-size-fits-all health advice doesn’t work for everyone
The Research Details
Researchers in Florence recruited 188 women aged 45-70 from a community health center in a lower-income neighborhood. Of these, 156 women completed a detailed questionnaire about their health knowledge and understanding. The questionnaire measured nine different areas of health literacy—basically, how well women understand health information and can use it to make good decisions.
The researchers used a statistical method called cluster analysis, which is like sorting people into groups based on similar patterns. Instead of treating all women the same, this method found that women naturally fell into four distinct groups based on their health knowledge strengths and weaknesses. The study also measured how well women understood nutrition information and whether they followed a Mediterranean diet, which is known to be heart-healthy.
This approach is called the Ophelia framework, which stands for ‘Optimising Health Literacy and Access.’ It’s designed to help doctors understand the specific needs of different groups so they can create better, more targeted health programs.
Understanding that women have different levels of health knowledge is important because it explains why some women struggle to follow heart disease prevention advice while others don’t. By identifying these different groups, doctors can stop giving everyone the same generic advice and instead create programs that match what each group actually needs. This is especially important for women in lower-income areas who may face extra barriers to getting good health information.
This study was published in BMJ Open, a respected medical journal. The researchers used a validated questionnaire (the Health Literacy Questionnaire) that has been tested and proven reliable in other studies. The study included 156 women with complete data, which is a reasonable sample size for this type of analysis. However, because this is a cross-sectional study (a snapshot in time), it shows associations but cannot prove that low health literacy causes poor heart health—only that they occur together. The study was conducted in one neighborhood in Italy, so results may not apply exactly to other countries or communities.
What the Results Show
The analysis revealed four distinct groups of women with different health literacy profiles. The largest group (48.7% of women) had several strengths in understanding health information but also had some specific challenges. About one-quarter of women (26.3%) showed a mix of strengths and weaknesses, along with limited social support from family and friends. A smaller group (16.7%) showed strong health knowledge across all areas measured. The smallest group (8.3%) faced widespread challenges in understanding health information.
Women in the groups with more health literacy challenges tended to have less education, more financial difficulty, and poorer overall health. These women also scored lower on nutrition knowledge and were less likely to follow a Mediterranean diet—a diet known to reduce heart disease risk. The differences between groups were statistically significant, meaning these patterns were not due to chance.
Interestingly, women in groups with stronger health literacy also reported a stronger sense of meaning and purpose in life. This suggests that understanding health information may be connected to overall well-being, not just heart health. The study shows that social support matters too—women with stronger connections to family and friends tended to have better health literacy.
The study found that nutrition literacy—understanding how to eat healthy—was directly connected to health literacy in general. Women who struggled to understand health information also struggled to understand nutrition advice. Additionally, adherence to the Mediterranean diet (eating more vegetables, fish, and olive oil, and less red meat) was significantly lower in women with weaker health literacy profiles. The sense of coherence—feeling that life makes sense and is manageable—was higher in women with stronger health literacy, suggesting that health knowledge contributes to overall life satisfaction.
Previous research has shown that health literacy is important for preventing chronic diseases like heart disease. This study adds to that knowledge by showing that health literacy is not one simple thing—it’s multidimensional, meaning it has many different parts. Some women might be good at understanding written health information but struggle to talk to doctors about their health. Others might understand the information but lack the social support or resources to act on it. This study confirms what other research has suggested: that one-size-fits-all health programs don’t work, and that social factors like education, money, and family support all play important roles in health outcomes.
This study has several important limitations. First, it was conducted in one neighborhood in Florence, Italy, so the results may not apply to women in other countries or communities with different healthcare systems or cultures. Second, the study is cross-sectional, meaning it’s a snapshot in time—researchers cannot prove that low health literacy causes poor heart health, only that they occur together. Third, the study did not measure actual heart disease outcomes; it only measured knowledge and diet adherence. Finally, the study included only women aged 45-70, so results may not apply to younger or older women. The researchers did not randomly assign women to groups, so there may be other unmeasured factors that explain the differences between groups.
The Bottom Line
Healthcare providers should assess each woman’s specific health literacy strengths and challenges rather than assuming all women understand health information the same way. For women with lower health literacy, doctors should use simpler language, provide written materials, and involve family members in health discussions. Community health programs should be tailored to match the specific needs of different groups. Women should be encouraged to ask questions and to bring a trusted family member or friend to health appointments. Following a Mediterranean diet (more vegetables, fish, whole grains, and olive oil) appears to be particularly important for heart health in this population. These recommendations are supported by moderate evidence from this study and previous research.
This research is most relevant to middle-aged and older women, especially those with less education or lower income. Healthcare providers, public health officials, and community health workers should pay attention to these findings when designing heart disease prevention programs. Women’s health advocates and policymakers should consider how to improve health literacy in vulnerable communities. However, these findings may not apply equally to men, younger women, or women in wealthier communities with better access to healthcare.
Changes in health knowledge and diet typically take 3-6 months to show measurable effects. Heart disease prevention is a long-term process, so women should expect to work on these changes over years, not weeks. Some women may see improvements in how they feel (energy, mood) within weeks of improving their diet and health knowledge, but actual reductions in heart disease risk take longer to develop.
Frequently Asked Questions
Why do some women struggle more to understand heart disease prevention information?
Education level, income, and social support all affect how well women understand health information. A 2026 study found that women with less education and financial difficulty had significantly lower health literacy and were less likely to follow heart-healthy diets, showing that barriers go beyond just intelligence or motivation.
What is the Mediterranean diet and why is it important for heart health in middle-aged women?
The Mediterranean diet emphasizes vegetables, fish, whole grains, olive oil, and nuts while limiting red meat. Research shows women who understand and follow this diet have better heart health outcomes, and the 2026 Florence study found women with stronger health knowledge were more likely to stick with this eating pattern.
How can doctors better help women who struggle to understand health information?
Instead of giving all women the same advice, doctors should assess each woman’s specific knowledge gaps and strengths. The 2026 study identified four different groups of women, suggesting personalized approaches—using simpler language, written materials, and involving family members—work better than generic programs.
Does having better health knowledge actually improve heart health outcomes?
This study shows that women with stronger health literacy are more likely to follow heart-healthy diets and report better overall health, but it doesn’t prove knowledge directly prevents heart disease. Long-term studies are needed to confirm whether improving health literacy actually reduces heart attacks and strokes in this population.
Are these findings about health literacy relevant to women in other countries?
The study was conducted in one lower-income neighborhood in Italy, so results may not apply exactly to other communities. However, the finding that health literacy varies and affects health behaviors is supported by research worldwide, suggesting the approach could work in other settings with local adaptation.

This research describes associations between health literacy and heart disease prevention behaviors in one Italian community and should not be interpreted as medical advice. Women concerned about their heart health should consult with their healthcare provider about personalized prevention strategies. This study does not prove that low health literacy causes heart disease, only that these factors occur together. Results may not apply to all women in all communities. Anyone making changes to their diet or health behaviors should discuss these changes with their doctor first, especially if they have existing health conditions or take medications.
