Most Prevalent Nutrition And Diet Related Diseases and Conditions Affecting U.S. Women
One important caveat: “nutrition- and diet-related” is broader than diseases caused by diet alone. Diet, nutrient intake, body weight, physical activity, and metabolic health can contribute to or modify many of these conditions, but genetics, hormones, age, pregnancy, medications, socioeconomic factors, and other causes also matter.
Using the latest nationally representative U.S. data available, I would rank the major conditions affecting women roughly as follows, starting with the most prevalent.
Chronological ranking — most prevalent first
| Rank | Disease / condition | Approx. prevalence in U.S. women | Why it belongs on a nutrition/diet list |
|---|---|---|---|
| 1 | Obesity | 41.3% of women ≥20 | Strongly influenced by energy intake, dietary pattern, food environment and physical activity; increases risk of diabetes, hypertension, CVD and several cancers. |
| 2 | Hypertension (high blood pressure) | 44.6% of women ≥18 (crude); 40.1% age-adjusted | Sodium, potassium, alcohol, body weight and overall dietary pattern substantially influence risk. |
| 3 | Anemia | 13.0% of females ≥2; 14.0% of women 20–59 | Iron deficiency is an important nutritional cause; menstruation and pregnancy increase women's risk. |
| 4 | Diabetes mellitus | 13.7% of women ≥20 | Strongly associated with excess body weight, diet and metabolic health; ~9.7% had diagnosed diabetes. |
| 5 | High total cholesterol | 11.9% of women ≥20 | Diet, body composition, genetics and physical activity affect blood lipids; especially important for cardiovascular disease. |
| 6 | Chronic kidney disease (CKD) | 14.7% of women ≥18 | Closely connected with hypertension and diabetes; dietary factors influence both risk and disease progression. |
| 7 | Osteoporosis | 19.6% of women ≥50 | Calcium, vitamin D, protein and overall nutritional status contribute to bone health, alongside menopause, age and genetics. |
| 8 | Binge-eating disorder | ~1.6% of adult women/year; 3.5% lifetime in older U.S. data | A clinically defined eating disorder involving recurrent binge eating; strongly relevant to nutrition and eating behavior. |
| 9 | Bulimia nervosa | ~0.5% of adult women/year; 1.5% lifetime | Eating disorder involving recurrent binge eating and compensatory behaviors. |
| 10 | Anorexia nervosa | ~0.9% lifetime among women | Less prevalent than metabolic/nutritional diseases but disproportionately affects women and can cause severe malnutrition and medical complications. |
1. Obesity — ~41.3% of U.S. women
This is probably the most useful starting point if you're looking specifically at nutrition-related disease burden.
NHANES data from August 2021–August 2023 found obesity in 41.3% of U.S. women age 20+, compared with 39.2% of men. Among women, prevalence was:
- 36.8%, age 20–39
- 47.4%, age 40–59
- 39.6%, age 60+
Severe obesity is particularly important because it was more prevalent in women than men in every age group.
Obesity isn't simply a consequence of individual food choices. The CDC describes it as a chronic disease with complex biological, environmental and behavioral determinants. It substantially increases risk of hypertension, type 2 diabetes, coronary heart disease, stroke and certain cancers.
2. Hypertension — ~44.6% of women
Interestingly, hypertension is even more prevalent than obesity when measured as a disease/risk condition.
CDC/NHANES data for 2021–2023 found hypertension in 44.6% of women age 18+ using the crude estimate, or 40.1% after age adjustment. Among women:
- 18–39: 16.4%
- 40–59: 49.0%
- 60+: 70.6%
Dietary sodium, potassium, alcohol consumption, body weight and overall dietary quality are important modifiable contributors, although hypertension is not exclusively a nutrition disease.
And the stakes are substantial: cardiovascular disease remains the leading cause of death in the United States.
3. Anemia — 13.0% of females
This is one of the clearest examples of a condition disproportionately affecting females.
The latest NHANES data show:
- 13.0% of females age 2+
- 5.5% of males
- 17.4% of girls 12–19
- 14.0% of women 20–59
Iron deficiency is an especially important nutritional contributor. CDC data indicate that 22.6% of U.S. females ages 12–49 had iron deficiency in the 2017–March 2020 NHANES data.
However, anemia should not automatically be assumed to mean iron deficiency. Blood loss, chronic disease, inflammation, inherited disorders and other conditions can cause it.
4. Diabetes — 13.7% of women
For women age 20+, the latest NHANES estimate is:
- 13.7% total diabetes
- 9.7% diagnosed diabetes
- approximately 3.9% undiagnosed diabetes
The age-adjusted figures are 12.2%, 8.6% and 3.5%, respectively.
Diabetes is particularly relevant to nutrition because prevalence rises substantially with increasing body weight, and diet and physical activity are important components of prevention and management.
The CDC's newer 2026 National Diabetes Statistics Report estimates 40.1 million Americans had diagnosed or undiagnosed diabetes in 2023, representing 12.0% of the U.S. population.
5. High total cholesterol — 11.9% of women
CDC's latest NHANES data show 11.9% of women age 20+ had total cholesterol ≥240 mg/dL, compared with 10.6% of men. The age-adjusted estimate for women was 11.3%.
There is an important age pattern:
- Women 20–39: 1.2%
- Women 40–59: 15.2%
- Women 60+: 16.4%
Diet is only one contributor—genetics and hormonal changes, particularly around menopause, can be important.
6. Chronic kidney disease — 14.7% of women
The CDC's 2026 CKD report estimates that 14.7% of U.S. adult women have chronic kidney disease, equivalent to about 19.7 million women.
CKD is particularly relevant to nutrition because dietary management becomes increasingly important as kidney function declines. More importantly for prevention, diabetes and hypertension are two of its major drivers.
This illustrates why simply ranking individual diseases can be misleading: obesity → hypertension/diabetes → CKD and cardiovascular disease can form a connected disease pathway.
7. Osteoporosis — ~19.6% of women ≥50
Osteoporosis is disproportionately a women's disease.
An analysis of NHANES 2017–2018 found osteoporosis in 19.6% of U.S. women age 50+, versus only 4.4% of men. Among women 65+, prevalence reached 27.1%. Even more striking, 51.5% of women ≥50 had osteoporosis or low bone mass.
Nutrition matters because inadequate calcium, vitamin D and protein can contribute to poor bone health. The National Institute on Aging specifically identifies inadequate calcium/vitamin D/protein intake as risk factors.
8–10. Eating disorders
These are far less prevalent numerically than obesity, hypertension or anemia, but they deserve inclusion because they are strongly sex-disproportionate and directly related to eating/nutrition.
National U.S. data found lifetime prevalence among women of approximately:
- Binge-eating disorder: 3.5%
- Bulimia nervosa: 1.5%
- Anorexia nervosa: 0.9%
compared with 2.0%, 0.5% and 0.3%, respectively, among men.
More recent DSM-5 data from a nationally representative sample of 36,306 U.S. adults similarly found that women had significantly higher odds of all three disorders.
A more useful way to think about the ranking
If your goal is women's nutrition and diet-related health, I would organize the evidence into four major disease clusters rather than treating every disease as independent:
1. Metabolic/nutritional diseases — largest population burden
Obesity → hypertension → diabetes → dyslipidemia → cardiovascular disease → CKD
These conditions affect tens of millions of American women and are interconnected. The CDC reports that nearly two-thirds of U.S. adults have at least one major cardiovascular risk factor, including high blood pressure, abnormal blood lipids, elevated glucose or high BMI.
2. Nutrient-deficiency diseases
Iron deficiency → anemia
This is particularly important among menstruating women and during pregnancy.
3. Nutritional bone disease
Inadequate calcium/vitamin D/protein + menopause/aging → low bone mass → osteoporosis → fractures
This becomes an enormous issue after menopause, with about 1 in 5 women over 50 having osteoporosis.
4. Disorders of eating/nutrition
Binge-eating disorder → bulimia → anorexia
These are much less prevalent than obesity or hypertension, but the sex disparity is substantial and the consequences can be severe.
One important correction to a simple "most prevalent" ranking
There isn't a scientifically clean single ranking because the denominator changes. For example, 41.3% obesity among women ≥20 cannot be directly compared with 19.6% osteoporosis among women ≥50 without acknowledging the different age groups. Similarly, anemia includes females age 2+, whereas diabetes is reported for adults.
So if you're using this for research, a presentation, a paper, or a health program, I would recommend ranking them using a standardized denominator—e.g., U.S. women age 18+—and separately showing prevalence, estimated number of women affected, mortality, and strength of the diet/nutrition relationship.
