What is the acculturation stress profile for African immigrant men, and why does it matter clinically?

Abera, in Ekegusii, the one who carries. African immigrant men arrive in the United States with a cardiovascular health advantage over US-born Black men: lower rates of hypertension, obesity, and diabetes at the time of immigration. The Afro-Cardiac Study documented that African immigrants who have resided in the US for ten or more years have nearly four times the odds of overweight or obesity and eight times the odds of elevated cardiovascular risk compared to recent arrivals. The advantage is real at arrival. It is systematically lost.

The mechanisms are specific: the American food environment (ultra-processed, high-sodium, calorie-dense) replaces the high-fiber, portion-appropriate ancestral diet. The American work culture does not reward rest in the way that communal African life structures recovery. The obligation calculus, remittances to parents, siblings' education fees, the expectation of being the family's economic engine in two continents simultaneously, generates a chronic cortisol load that no lab panel captures because no physician asks. And the first-generation immigrant's cultural model of health often does not include preventive cardiology: you see a doctor when something hurts, not to check numbers that feel fine. By the time the numbers announce themselves, years of silent accumulation have occurred. (Afro-Cardiac Study, PubMed 28852948)

Cardiologist's calibrated position, Solid (1) for the acculturation effect from the Afro-Cardiac Study. Promising (2) for the remittance-stress-cortisol-cardiovascular pathway (mechanistically plausible, not yet specifically studied in a dedicated trial).

What to do: If you are an African immigrant man who arrived here more than ten years ago and has not had a cardiovascular risk assessment including Lp(a), ApoB, home blood pressure, and a direct family history review, you are in the population this statistic describes. The screening is not optional.
