^§Odds ratio (OR) greater than 1 indicates that a participant who owns a phone has a greater likelihood of engaging in this behavior as compared to someone who does not own a phone. OR less than 1 indicates that a participant who owns a phone has a lower likelihood of engaging in this behavior as compared to someone who does not own a phone.

^†N are the person-rounds of each stratified group that were used to fit the models for odds ratios.

^‡The OR were adjusted for visit rounds, location, SES, religion, education, current marital status, and occupation.

^§The OR were adjusted for number of sexual partners, alcohol use before sex, and inconsistent condom use.
