Key result
Pre-hypertension was the strongest predictor of incident hypertension (adjusted OR 12.9), with an overall age-standardized incidence rate of 21.54 per 1000 person-years over a 4-year follow-up.
Why the study?
Hypertension is a significant global public health concern, but its incidence and associated risk factors among adults aged 40 and above in southern Iran needed estimation.
What are the incidence rate and predictors of hypertension in adults aged 40-70 years in southern Iran?

What are the incidence rate and predictors of hypertension in adults aged 40-70 years in southern Iran?
Odds Ratio: 12.9 (95% CI 6.45–25.9)
p-value: p=<0.05
The study identifies an incidence of 21.54 per 1000 person-years for hypertension in southern Iran, highlighting advanced age, female sex, obesity, opioid use, and pre-hypertension as key risk factors.
Identifies sex-specific HTN predictors in southern Iran; leaves open whether gender-targeted prevention improves outcomes elsewhere.
Background: Hypertension (HTN) is a significant public health concern globally. The study aims to estimate the incidence of HTN among adults aged 40 and above in southern Iran and identify the risk factors associated with it. Methods: The participants in the present prospective cohort study consisted of 7710 people aged 40–70 years. HTN is defined according to European guidelines for HTN management. Firth Logistic regression was used to model and predict the factors related to HTN. Additionally, the age standardized incidence rate (ASPR) of HTN was determined using the standard Asian population. Results: The study found that the incidence rate of HTN during the four-year follow-up was 21.54 per 1000 person-years, with higher incidence in females than males. Risk factors for developing HTN included being old, female, obesity, and using opium. Clinical risk factors included pre-HTN, family history of HTN, rheumatoid disease, kidney stones, recurrent headaches, history of head injury with anesthesia, and high triglyceride levels. Conclusion: The incidence of HTN was greater in women than in men. Furthermore, pre- HTN, advanced age, obesity, opioid use, and family history of HTN were the most significant risk factors for developing HTN. Therefore, it is advisable to develop strategies to lessen modifiable risk factors.

Rezaianzadeh et al. (2023) conducted a cohort in Hypertension (n=7,710). Pre-hypertension vs. Normotension was evaluated on Incidence of hypertension (OR 12.9, 95% CI 6.45-25.9, p=<0.05). Pre-hypertension was the strongest predictor of incident hypertension (adjusted OR 12.9), with an overall age-standardized incidence rate of 21.54 per 1000 person-years over a 4-year follow-up.
