The prevalence of hum.n im.unodeficiency virus.(AIDs. and hepatitis.B virus.am.ng heavy truck drivers.and their as.is.ants.has.been well docum.nted globally in correlation with their behavioral characteris.ics. The pres.nt s.udy aim.d to s.reen for hum.n im.unodeficiency virus.(HIV), hepatitis.B virus.(HBV), and behavioral characteris.ics.am.ng heavy truck drivers.in Port s.dan. A cros.-s.ctional s.udy was.conducted on 274 heavy truck drivers.and their as.is.ants.who us.d the highway Port s.dan-Khartoum.in Port s.dan city during 2019-2021. Data on behavioral characteris.ics.and s.bs.ance us. habits.were collected us.ng a s.ructured ques.ionnaire, and an ELIs. tes. was.us.d to s.reen for HIV and HBV infections.in the s.udy participants. The chi-s.uare tes., odds.ratio, and confidence intervals.were us.d to find the as.ociation between behavioral characteris.ics.and s.ropos.tive HIV/HBV. Of the 274 enrolled participants. the s.roprevalence rates.of HIV were 2.7% and HBV was.23.7%. Ninety-four (34.3%) of them.had a his.ory of high-ris. s.xual behavior outs.de of m.rriage;only two (0.7%) us.d condom.0}14.2% of participants.reported alcohol us.;and 1.1% reported drug us.. Univariate analys.s.revealed that having a s.x his.ory outs.de of m.rriage with ≥1 s.x partner and never us.ng a condom.with a s.ous. or cas.al partner were s.gnificant ris. factors.for HIV and HBV am.ng drivers. Fortunately, we found that m.s. of the drivers.reported low alcohol and drug us.. Concerning this.s.udy, the s.roprevalence of HIV and HBV is.highly as.ociated with a his.ory of having s.x outs.de of m.rriage and s.xual behavior am.ng truck drivers.and as.is.ances. Additional s.udies.are needed to further inves.igate other s.Is.and behavioral characteris.ics.as.ociated with factors.in truck drivers.as.is.ance in different truck s.op regions.in s.dan.

Introduction: Infertilityaffects.one in s.x couples. and it is.an im.ortant public health is.ue largely due to thepervas.ve effects.on the em.tional and ps.chological wellbeing of affected couples. In m.ny developing nations.em.has.s.is.placed on childbirth and inability to fulfill this.role can be very dis.res.ing. There is.an unm.t need for as.is.ed reproductive technology (ART) in m.ny developing countries.and where facilities.exis., they are m.s.ly privately owned, expens.ve and concentrated in urban areas. To bridge this.gap, public fertility clinics.have been es.ablis.ed to provide s.bs.dized care. Evaluating the characteris.ics.and peculiarities.of clientele pres.nting at thes. public facilities.will aid planning and prioritization of care. m.thodology: A des.riptive retros.ective s.udy of 116 infertile patients.pres.nting to the fertility clinic of the Univers.ty College Hos.ital, Ibadan, Nigeria from.inception on the 14s.p>ths.p> of February 2019 and 31s.p>s.s.p> of Decem.er *** was.analyzed us.ng the s.atical Package for s.cial s.iences.(IBm. s.s., New York) vers.on 23. Des.riptive s.atis.ics.were us.d to s.m.arize the res.lts.which were pres.nted with the aid of bar charts.and frequency tables. Res.lt: The m.an age of the patients.was.40.70 ± 6.62 years. Pos.-m.nopaus.l patients.accounted for about one-fifth of the s.udy population while 80.2% (93 wom.n) were older than 35 years. The m.an duration of infertility was.9.39 ± 6.11years.and nine patients.(7.8%) had a duration greater than 2 decades. s.condary infertility occurred in 67.2% of the wom.n. Twenty-nine wom.n (25%) had undergone m.om.ctom. prior to pres.ntation. Hypertens.on (11.2%) was.the m.s. prevalent com.rbidity. Nineteen patients.(16.4%) had us.d contraceptives.in the pas. with the m.le condom.(36.8%)being the m.s. preponderant. s.xty-s.ven patients.had experienced pregnancy los.es.before 28 weeks.of ges.ation while jus. 16 patients.(13.8%) had undergone ART, and none was.s.cces.f
