In Northern Thailand, little research has been conducted on the diversity of young
people’s sexual and/or gender identities which may affect their lifestyles, sexual
relationships and health consequences. Instead, most studies have focused more narrowly
on sexual behaviours and associated health risk outcomes (van Griensven et al 2004) or on
narrowly defined groups such as kathoey (Totman 2003) or male bar workers (De Lind van
Wijngaarden 1999).
