Cardiovascular disease marker prevalence varies significantly across countries due to complex interactions between dietary patterns, lifestyle factors, genetic predispositions, healthcare access, and socioeconomic conditions. Our research found that countries with strong Mediterranean dietary adherence like Italy at 35.2% and France at 36.7% showed lower cardiovascular markers compared to the United States at 44.8% and Belgium at 40.9%. The so called French Paradox, where traditional French dietary patterns correlate with lower cardiovascular risk despite fat intake, was partially supported by our findings. Cultural factors including meal timing, portion sizes, physical activity integration into daily life such as cycling in the Netherlands and Belgium, and traditional food preparation methods all contribute to these variations. Our AI analysis platform helps individuals understand their personal cardiovascular risk profile within the context of these population level trends.

Our research found vitamin D deficiency rates of 47.3% in the Netherlands, 44.6% in the United Kingdom, and 43.8% in Belgium, representing the highest rates among all countries studied. This elevated prevalence is primarily attributable to northern latitudes where UVB radiation from sunlight, necessary for vitamin D synthesis in skin, is insufficient during autumn and winter months. Between October and March, people living above 37 degrees North latitude cannot produce adequate vitamin D from sun exposure regardless of time spent outdoors. Additionally, modern indoor lifestyles, use of sunscreen, and darker skin pigmentation in multicultural populations further compound deficiency risk. Our blood test analyzer consistently flagged these patterns, supporting public health recommendations for vitamin D supplementation of 2000 to 4000 IU daily during winter months in northern countries.

The frequency of blood testing depends on individual health status, age, risk factors, and any existing medical conditions. For generally healthy adults without known health issues, comprehensive blood work annually is typically recommended by most healthcare authorities. However, individuals with chronic conditions such as diabetes, cardiovascular disease, or thyroid disorders may benefit from more frequent monitoring every 3 to 6 months. Our AI blood test analyzer provides trend analysis features that help users track changes in their biomarkers over time, making it easier to identify patterns that warrant medical attention. Users over 40, those with family history of chronic disease, or individuals taking medications that affect liver or kidney function should discuss optimal testing frequency with their healthcare providers.

Kantesti AI distinguishes itself from competitors through several key differentiators. First, we use a proprietary 2.78 trillion parameter neural network specifically developed for blood biomarker analysis rather than relying on generic large language models or third party APIs like many competitors. Second, our platform has been validated by a team of board certified physicians including clinical hematologists, pathologists, and laboratory medicine specialists, achieving clinical accuracy rates between 98.7% and 99.84%.

We always recommend that users share their Kantesti AI reports with their doctors as a starting point for meaningful healthcare conversations.

The findings from our January 2026 Global Health Intelligence Report contribute valuable population level data to the broader understanding of chronic disease prevalence and regional health patterns. We share anonymized, aggregated research findings with healthcare institutions and public health organizations to support evidence based policy development. Our identification of underdiagnosed conditions such as the 18.7% subclinical thyroid dysfunction rate in users without prior diagnosis, and the elevated anemia prevalence in specific demographics like French women aged 18 to 45, provides actionable insights for screening program optimization. We plan to continue publishing quarterly reports as our dataset grows, providing ongoing surveillance of global health trends.
