Key result
An inter-arm systolic blood pressure difference of ≥10 mmHg was present in 11% of subjects and was associated with a family history of diabetes or hypertension.

No
An inter-arm systolic blood pressure difference of ≥10 mmHg is prevalent among young medical students and is associated with a family history of hypertension or diabetes.

May warrant inter-arm BP checks in young adults with family history; hypothesis-generating for early risk stratification.
Background: Blood pressure (BP) recordings often differ between arms. This study is aimed to observe the presence of inter-arm blood pressure difference and association with hypertension or diabetes. The objective of the study was to establish the prevalence of an inter-arm blood pressure difference and explore its association with obesity and cardiovascular disorder.Methods: A cross-sectional study conducted at King George’s Medical College, Lucknow, India among 100 first year MBBS students. After taking verbal consent the age, height, weight, waist circumference, hip circumference and family history of hypertension or diabetes were recorded.Results: The systolic blood pressure on right arm was 118.8±11.5 mmHg and 11.7±7.72 mmHg left arm. Result significantly showed higher mean systolic blood pressure on right arm. There were 54, 17 and 29 participants with inter-arm systolic blood pressure difference of <5 mmHg, 5 to 10 mmHg and ≥10 mmHg, respectively. 10 subjects having BMI range between 25-29.9 and only one subject found obese (BMI >30). Out of 100 subjects, 11 subject having inter-arm systolic blood pressure difference ≥10 mmHg was associated with a family history of diabetes or hypertension.Conclusions: Presence of inter-arm blood pressure difference with having family history of hypertension or diabetes is more susceptible to develop cardiovascular disorder in future.

Verma et al. (2016) conducted a cross-sectional in Healthy subjects (n=100). Inter-arm systolic blood pressure difference ≥10 mmHg vs. Inter-arm systolic blood pressure difference <9 mmHg was evaluated on Association of inter-arm systolic blood pressure difference ≥10 mmHg with family history of diabetes or hypertension. An inter-arm systolic blood pressure difference of ≥10 mmHg was present in 11% of subjects and was associated with a family history of diabetes or hypertension.
