Methods:In May 2015 we electronically searched the following databases with no date restrictions: MEDLINE, EMBASE and ISI the Web of Science using a detailed search strategy with no language restrictions. We also screened references lists of included studies. We also screened the references lists of the included studies. We included cohort, case-control and crosssectional studies, and excluded case reports, conference abstracts, editorials and reviews. We excluded studies not conducted in humans, assessing physiological outcomes, not distinguishing waterpipe tobacco smoking from other forms of smoking, and not reporting association measures. We assessed risk of bias for each included study and conducted meta-analyses for each of the outcomes of interest. Results:We identified 50 eligible studies. We found that waterpipe tobacco smoking was significantly associated with respiratory diseases (COPD odds ratio (OR)= 3.18, 95% CI= 1.25, 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 Conclusions:There is accumulating evidence about the association of waterpipe tobacco smoking with a growing number of health outcomes.

“…In North African countries, such as Tunisia-AlgeriaMorocco, case-witness studies, suggested that salted foods prolonged consumption, like quaddid (dried mutton stored in oil), harissa (spicy salted sauce, rancid butter and khelii (dried meat, salty, spicy, cooked and preserved in a mixture of oil and melted bovine greases) is associated with increased NPC risk (Feng et al, 2007) Other environmental factors such as tobacco, cannabis and domestic cooking fumes intake (cooking in the main living room) during childhood, have recently been described as a risk factors for NPC in North African countries as in Tunisia (Feng et al, 2009). We're always observing in North Tunisia a bimodal distribution characterized by 2 peaks at 15 -20 years old and a second at 50 years old, previously reported in several intermediate-risk populations in Northern Africa (Tabyaoui et al, 2013) and Western Asia (Andejani et al, 2004;Barista et al, 2007;Tsao et al, 2014;).…”

Nasopharyngeal carcinoma (NPC) is the second most common neoplasm of head and neck in Tunisia. The distribution is bimodal with a first period occurrence between 15 and 20 years old and a second peak at around 50 years of age. Undifferentiated carcinoma of nasopharynx type III (UCNT) is the predominant histological type (93.4%). Data of cancer registry of North Tunisia confirmed that it is an intermediate risk area for NPC with overall ASRs of 3.6 and 1.6/100,000 respectively in males and females. This study aimed to present the evolution of incidence rate of nasopharyngeal carcinoma over a period of 12 years (1994)(1995)(1996)(1997)(1998)(1999)(2000)(2001)(2002)(2003)(2004)(2005)(2006). Data of cancer registry of North Tunisia (NTCR), covering half of the Tunisian population, were used to determine evolution of NPC incidence, calculated by 5 year periods. The estimated annual percentage change (EAPC) was used as an estimate of the trend. To best summarize the behavior or the data trend across years, we used a join-point regression program. Between 1994 and 2006, we observed negative annual average change of standardized incidence in men and women (-3.3%and -2.7%) also for the standardized incidences which showed a rather important decline (26.4% in males and 22.3% in females). The truncated age standardized incidence rate of NPC in adults aged of 30 years old and more (N= 1209) decreased by -0.4% per year from 1994 to 2006 over time in north Tunisia dropping from 6.09 to 4.14 person-years. However, the rate was relatively stable during this period among youths aged 0-29 years (N= 233) in both sexes. NPC demonstrated a favorable evolution from 1994-2006 probably due to a improvement in socioeconomic conditions.
