Abstract:
This study examines (1) the construct validity of a rank-order skin color measure and (2) interrelationships of skin color, ancestry, and blood pressure in a random survey of 763 white non-Hispanic and white Hispanic household residents in Erie County, NY. Skin color was significantly lighter among older respondents (P < .001) and among females (P < .0001). Skin color was lightest among Northern Europeans and darkest among Mediterraneans and white Hispanics (P < .0001). Higher systolic blood pressure was significantly associated with both darker skin color (P < .05) and northern European ancestry (P < .05). Several mechanisms to account for these findings are proposed.

Factors affecting Blood pressure
Physiological Factors:
Assessment of blood pressure in brachial artery(one-step method)
Prepare for the Procedure:
Special considerations while measuring blood pressure
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
