That's a typical association, not necessarily a causal relationship.
For example, those with rich diets gave birth to financially comfortable
children, who ate a rich diet, who gave birth to financially comfortable
children, who ate a rich diet. All generations may have worked at
relatively sedentary occupations too. So what caused the higher rates of
diabetes: rich diets?, genetics?, transfer of insulin resistance in the
womb?, sedentary occupations...????
