Original ResearchSkin-lightening practices among female high school students in Ghana
Introduction
Skin lightening (SL) is the use of chemical agents to lighten the complexion of the skin. It is also called skin whitening or bleaching. The practice is global but has severe implications for vulnerable populations in sub-Saharan Africa (SSA) where despite concerns about the harmful health effects, prevalence remains high. Estimates of between 30% and 70% have been reported.1, 2, 3, 4
The practice of SL in SSA is founded on the belief that the lighter the tone of the skin, the more desirable and attractive a person becomes.5 It has been argued that colonialism in most of SSA and apartheid in South Africa reinforced the superiority notion associated with the lighter skin.6, 7 The desire for lighter skin tone is not unique to SSA.8 Considerable commercial interest in SL products helps to sustain the culture of appreciation for the lighter skin.9 Some African music and arts celebrities have publicly admitted to using SL products.10 It is thought that they do this to attract greater attention and commercial works. In some cases however, SL is a continuum of a habit acquired during adolescence; long before they became celebrities.11
The health risks posed by SL derive from the effects of the hydroquinone, mercury, and corticosteroids that are commonly found SL products.12 Hydroquinone is the most effective SL agent known yet. It has therapeutic application in the management of skin conditions that are characterized by hyperpigmentation.13, 14, 15, 16 Hydroquinone acts by strongly inhibiting melanin production, and thereby leaving the skin depigmented. Prolonged use of hydroquinone is associated with the development of exogenous ochronosis and other skin conditions.17, 18 Mercury is also used in SL because its salts inhibit the formation of melanin.19 Increased blood levels of mercury have been reported with therapeutic and cosmetic use of mercury-containing products.20, 21 Damage to the kidney is one of the major adverse effect of the use of mercury-containing SL products. Corticosteroids are often used in combination with hydroquinone and mercury in SL products.22 These cause SL through vasoconstriction which over time leads to hypopigmentation. Clobetasol propionate is a popular form of corticosteroid used in SL products. The major side-effect of corticosteroid use in SL is cutaneous atrophy which manifest as skin fragility, telangiectasia, and striae.12, 23 A major challenge to efforts of discouraging the practice of SL is the fact that whereas the desired effect of a lighten skin manifest early after use of SL products, the harmful effects manifest only after several years of use. Women have been known to use SL creams for as long as 20 years before manifesting harmful effects.24, 25
Adolescence is a vulnerable yet critical formative period in the life course.26 Many adolescents experience a wide range of adjustments. Behavior patterns that are established during this process, such as drug use or non-use and sexual risk taking or protection can entrench and have long-lasting positive and negative effects on future health and well-being.27, 28, 29 On the other hand, adolescence offers a period that adults can have unique opportunities to influence young people. It is a window of opportunity to curb undesirable health-risk habits before they become intractable.30
In Ghana, adolescents between the ages of 13–18 years are expected to be in high school where the role-model influence of teachers and parents are expected to guide them to negotiate this critical period. Not much is known about the use of SL by adolescents in Ghana. This study is an attempt to establish the prevalence of SL among high school students in Ghana and to explore factors associated with the practice.

Study sites
The Brong Ahafo Region is one of the 10 administrative regions in Ghana. It is located in the middle-belt of the country and is home to the ‘Bonos’ and ‘Ahafos’ (both regarded as ‘Akans’), as well as migrants from the north and south of the country. Each of the 27 districts in the region has at least one senior high school (SHS). The SHS program in Ghana is a 3-year pre-university program where students, usually aged between 15 and 18 years, attend schools either as boarders or day students. In
Results
All selected 410 students completed the questionnaire. The mean age of students was 17.6 (standard deviation = 1.6) years. There was an equal proportion of day students (48.8%) and boarding students. The majority (77.1%) of students were Christians. Most (98.9%) of the rest were Muslims. The four main ethnic groups represented in the sample were Akan (41.5%), Guans (15.6%), and the combination of Hausas, Dagaras, and Walas (14.4%). The students were in form 1 (36.8%), form 2 (30.2%), and form 3
Discussion
This study applied a cross-sectional design to explore the practice of SL in selected SHS in the Brong Ahafo Region. This study is a particularly important addition to the literature on SL in sub-Saharan Africa because it was conducted among adolescents, about whom very little is known regarding SL. The majority of work in this field in SSA has been among university students and older adults.5
The proportion of students admitting to having used SL products in this survey is very high. It is just
