Preventive Health for Men Over 50

The numbers worth tracking, which screenings have evidence behind them, and which expensive tests I decided to skip. Written by a patient who reads the guidelines, not a doctor who writes them.

Start with blood pressure

Table of five health numbers to track after 50: blood pressure, LDL cholesterol, ApoB, A1C and waist, each with the number to aim for and the guideline it comes from.
Where each of these numbers comes from

Unlike a single-trial chart, this one pulls from four different bodies, so each row names its own rather than pretending they are one set. All verified against the source documents in August 2026.

NumberSource, and the exact wording
Blood pressure2025 AHA/ACC high blood pressure guideline. Normal is defined as under 120 and under 80, and that is the number this page tells you to aim for. The guideline’s formal treatment goal is the looser <130/80 mm Hg, with exceptions for people in institutional care, with limited life expectancy, or who are pregnant. So 130/80 is where the guideline says treatment has done its job, and 120/80 is the line it calls normal. Commentaries on the guideline describe it as encouraging people below 120/80 as well, but that is their characterisation and not wording I have been able to check in the guideline itself. Stage 1 hypertension is 130 to 139 or 80 to 89.
LDL cholesterol2026 ACC/AHA dyslipidemia guideline. Its goals come as pairs with non-HDL cholesterol: <100 (non-HDL <130) at borderline to intermediate risk, <70 (non-HDL <100) at high risk or with subclinical atherosclerosis, and <55 (non-HDL <85) for clinical ASCVD that is at very high risk. That last split is the one people get wrong: having heart disease does not automatically put you at 55. The guideline gives <70 to clinical ASCVD that is not very high risk, and defines very high risk as two or more major events, or one major event plus two or more high-risk features.
ApoB2026 ACC/AHA dyslipidemia guideline, which calls apoB measurement “reasonable” for adults already on lipid-lowering therapy, to guide further treatment once the LDL and non-HDL goals are met. It is a refinement test rather than a universal one, and the reason to bother is discordance: LDL can read at goal while apoB stays elevated. The two apoB goals stated in its recommendation text are <100 mg/dL alongside the LDL <100 goal, and <55 mg/dL at the severe and very-high-risk end once the LDL and non-HDL goals are met.
A1CAmerican Diabetes Association, Standards of Care in Diabetes—2026, section 2. Its table 2.2 defines prediabetes as A1C 5.7 to 6.4%, and table 2.1 diagnoses diabetes at A1C 6.5% or above on a lab test standardised to the reference assay. The ADA adds the part worth carrying: for all of these tests “risk is continuous, extending below the lower limit of the range”, so 5.6 is not a safe zone and these are the lines where a diagnosis starts, not treatment targets. Someone already diagnosed sets a different goal with their doctor.
WaistNICE guideline NG246: keep your waist to less than half your height, a ratio under 0.5. It classifies 0.4 to 0.49 as healthy, 0.5 to 0.59 as increased and 0.6 or more as high central adiposity, for adults with a BMI under 35 of any sex or ethnicity, including people carrying a lot of muscle.
The LDL and apoB rows are the ones most often quoted wrong. Which tier applies to you comes from a calculated risk score, not from your age, and the guideline sets no formal LDL goal at all for genuinely low-risk adults. If a number here does not match what your doctor told you, they have your risk score and this chart does not.

What men over 50 should know

The measurable part of preventive health after 50 comes down to five numbers, and almost nobody hands you the list. I had to assemble mine from four different guidelines, which is a ridiculous amount of work for something this basic. The one that surprised me is blood pressure. Under 120 over 80 is what actually counts as normal, and it is what I aim for. The formal treatment goal in the 2025 guideline is the looser under 130 over 80. Two real numbers, constantly confused for each other, and the gap between them is where a lot of men sit and assume they are fine.

The boring numbers are the ones with the evidence, which is not how any of this gets sold. A blood pressure cuff costs almost nothing and it is the reason I take a pill every morning. A tape measure around your waist is simpler than BMI, and it tracks the fat that does the damage, and the rule is easy enough to remember: keep it under half your height. Meanwhile the things being advertised to men my age, the full-body MRI, the hundred-biomarker panel, the biological-age report, come with no target and no evidence that ordering them makes you healthier. I am not immune to wanting them. I have written about how fast that curiosity turns into shopping, and about the version that costs forty thousand dollars a year.

I am a patient here, not a clinician, and I track these because I got the bad version of the news first. My own cholesterol panel is the reason I care that apoB and LDL can disagree, and that the number your doctor quotes depends on a risk score rather than your birthday. The rest of this page is what I have read and checked: the screenings worth having, the ones that are genuinely your call, and the expensive tests I decided to skip. Where the evidence is thin I say so, because a test that finds something you would never have died from still gets you the biopsy, the scan, and the year of worrying.
