Inter-arm difference in systolic blood pressure: Prevalence and associated factors in an African population

Abstract

Objectives Inter-arm blood pressure difference (IABPD) can lead to underdiagnosis and poor management of hypertension, when not recognized and are associated with increased cardiovascular mortality and morbidity. However, the prevalence and associated risk factors of IABPD in sub-Saharan Africa are unknown. This study aims to determine the prevalence and associated risk factors of IABPD among Tanve Health Study (TAHES) participants, a cohort about cardiovascular diseases in a rural area in Benin. Methods The cohort was conducted since 2015 among adults aged 25 years and over in Tanve village. Data were collected from February to March, 2020. Brachial blood pressure were recorded at rest on both arm with an electronic device. Systolic IABPD (sIABPD) was defined as the absolute value of the difference in systolic blood pressure between left and right arms ≥ 10 mmHg. A multivariate logistic regression models identified factors associated with sIABPD. Results A total of 1,505 participants (women 59%) were included. The mean age was 45.08 ±15.65 years. The prevalence of sIABPD ≥ 10 mmHg was 19% (95%CI: 17–21). It was 19% (95%CI: 16–22) in men and 20% (95%CI: 17–22) in women. In final multivariable model, the probability of sIABPD ≥ 10 mmHg increased significantly with age (adjusted OR (aOR) = 1.1; 95%CI: 1.02–1.20 per 10-years), hypertension (aOR = 2.33; 95%CI: 1.77–3.07) and diabetes (aOR = 1.96; 95%CI: 1.09–3.53). Conclusion Almost quarter of sample have a sIABPD ≥ 10 mmHg, with an increased risk with older age and hypertension and diabetes.

Association of interarm blood pressure difference with selected body circumferences among Walter Sisulu University community

“…Absolute BP difference or absolute value of R –L (|R –L |) was calculated to determine the difference between left-arm BP and right-arm BP regardless of which arm showed a higher BP value [ 10 ]. A large inter-arm BP difference was defined as an absolute interarm BP difference of greater than 10 mmHg [ 22 , 23 ]. The BP was categorized into prehypertension (SBP = 130–139, DBP = 80–89 mmHg),and hypertension (SBP ≥ 140 mmHg or DBP ≥ 90 mmHg) depending on the arm with the higher values [ 3 ].…”

Association between inter-arm blood pressure difference and cardiovascular disease: result from baseline Fasa Adults Cohort Study

“…Inter-arm blood pressure difference can be easily measured in outpatient clinics 3 , and in most cases, there is a difference between the blood pressure of each arm 4 . 10 mmHg and above is defined as an increase in inter-arm SBPD difference 5 and it can be found in more than 24% of healthy people 6 . Detection of this difference is important for diagnosing and treating hypertension 7 .…”

“…En effet, le risque de mortalité cardiovasculaire était élevé à 58 % chez les patients atteints d'asymétrie tensionnelle systolique entre les bras ≥ 10 mm Hg (8). En 2022, selon une étude réalisée chez 1505 populations Africaines au Benin, près du quart de l'échantillon a une différence de pression artérielle systolique entre les deux bras ≥ 10 mmHg, avec un risque accru avec l'âge, l'hypertension et le diabète (10).…”
