The Prevalence of High Blood Pressure among Marathon Runners during Beirut-Marathon 2014

Marathon is a long-distance running race. It is one of the endurance events which have some health benefits. However, the incidences of sudden cardiac deaths that have occurred during marathons imply an element of risk as well. In this paper, the authors aimed to assess the prevalence of high blood pressure (BP) and cardiovascular risk factors among marathon runners during Beirut-Marathon 2014.

A total of 325 marathon runners were divided into 42 km (30 runners) and 10 km groups (295 runners). They were assessed for cardiovascular risk factors by measuring their BP and answering a questionnaire. The questionnaire composed of 22 questions related to demographic information, risk factors, medical history, family history, medical checkups, use of antihypertensive drugs and definition of hyponatremia. 

The results demonstrated that 1) the majority of 42 km runners were males 29 (96.7%) vs. 205 (69.5%) in the 10 km group, (P = 0.001); 2) The age of the runners in 42 km group was older than that in 10 km group (47 ± 13.8 years old vs. 38.5 ± 14.6 years old; P = 0.0025); 3) The prevalence of hypertension was 46.7% in the 42 km group as compared to 31.2% in the 10 km group (P = 0.08); 4) Systolic BP (SBP) was higher in 42 km group vs. 10 km group (143 ± 22.4 mm Hg vs. 129.9 ± 17.8 mm Hg; P = 0.0004); 5) The heart rate was lower among 42 km vs. 10 km group (71 ± 11.1 bpm vs. 84 ± 16 bpm; P < 0.0001); 6) Only 10% of the runners in both groups reported that they had hypertension (HTN).

In summary, there is a high prevalence of HTN among marathon runners but minorities were aware that they had hypertension. The 42 km runners tend to be older with higher systolic blood pressure as compared to the 10 km runners.

Does Immigration Promote the Investment of the Monopolistic Firm?

In the present paper, we examine the effect of increasing uncertainty of immigrants’ growth on the optimal timing of investment of a firm that has a monopolistic power over the labor market. It is revealed that when the uncertainty of immigrants’ growth is more than a threshold level, increasing uncertainty of immigrants’ growth accelerates the optimal timing of firms’ investment and enhances the economic growth, even if the uncertainty of immigrants’ growth is formulated by the geometric Brownian motion, which is in sharp contrast to the standard result that an increase in the uncertainty postpones the optimal timing. With an increase in the immigrants over the past ten years, workforces in the host countries have been growing significantly to the extent that the immigrants represent 70% of the increase in the workforce in Europe, and 47% in the United States as OECD indicates. In the present paper, we attempted to investigate the effect of increased uncertainty caused by the growi...
