Nutritional status, weight perception and weight control practices among office employees in Sokoto, Nigeria

Autor: Kehinde Joseph Awosan, Semiyu Adetunji Adeniyi, Hamza Bello, Zarau Bello-Ibrahim

Publikováno v: The Pan African Medical Journal, Vol 27, Iss 279 (2017)

INTRODUCTION: Overweight and obesity have become the fifth leading risk for global deaths. Office employees have been identified as a high risk group due to the sedentary nature of their work, and accurate weight perception is believed to be critical

Contribution of Increases in Late Systolic Ejection Volume to the Impact of Heart Rate on Central Arterial Pulse Pressure in a Community Sample

Autor: Nonhlanhla Mthembu, Gavin R Norton, Vernice R Peterson, Ravi Naran, Suraj M Yusuf, Grace Tade, Hamza Bello, Adamu Bamaiyi, Carlos D Libhaber, Patrick Dessein, Ferande Peters, Pinhas Sareli, Angela J Woodiwiss

Publikováno v: American Journal of Hypertension. 35:989-997

BACKGROUND A lower heart rate (HR) increases left ventricular (LV) ejection volume. Whether this contributes to the adverse effects of HR on central pulse pressure (PPc) through reservoir volume effects is uncertain. METHODS Using noninvasive central

Publikováno v: Hypertension (Dallas, Tex. : 1979). 80(1)

Background: Whether systolic blood pressure (SBP) control in sustained volume-dependent primary hypertension is associated with blunted ANP (atrial natriuretic peptide) relationships with indexes of volume load is unknown. Methods: Systemic hemodynam

Independent relationships between renal mechanisms and systemic flow, but not resistance to flow in primary hypertension in Africa

Publikováno v: Journal of Hypertension. 39:2446-2454

AIMS Whether renal mechanisms of hypertension primarily translate into increases in systemic vascular resistance (SVR) in all populations is uncertain. We determined whether renal mechanisms associate with either increases in SVR (and impedance to fl
