Patterns and correlates of pubertal development in Canadian youth: effects of family context

BACKGROUND: Current health literature suggests that there has been a decline in the age of pubertal onset, and that pubertal development is influenced by social context. Unfortunately, contemporary Canadian-specific data have not been available. This study examined the odds of having entered puberty at various ages during adolescence, before and after controlling for the effects of family socio-economic status and family structure. METHODS: Longitudinal data for this study were drawn from the first four cycles of the National Longitudinal Survey of Children and Youth. The final sample consisted of 7977 adolescents ranging in age from 10 to 17. Pubertal status of the participants was identified based on pubic hair, facial hair growth, and voice change, for boys; and pubic hair, breast development, and menstruation, for girls. Trajectories of pubertal development were analyzed with HLM growth curve modelling techniques. RESULTS: The results indicated that, compared to boys, the odds of having entered puberty at age 13 were 6.45 times higher for girls and that girls go through puberty more quickly. Low family socio-economic status and living with a stepfather were found to predict early onset of pubertal development. CONCLUSION: Contextual factors are related to pubertal development. Additional research is needed to develop a more solid understanding of how psychosocial factors interact to predict gendered patterns of pubertal development.

Socio-economic status and puberty are the main factors determining anaemia in adolescent girls and boys in East Java, Indonesia

OBJECTIVE: To determine prevalence and contributing factors of anaemia in adolescents. DESIGN: Cross-sectional study of anaemia prevalence, socio-economic status and puberty. SETTING: Schools in East Java, Indonesia. SUBJECTS: Male and female adolescent pupils (age 12-15 y; n=6486). RESULTS: Anaemia prevalence was 25.8% among girls (n=3486), 24.5% among pre-pubertal boys (n=821), and 12.1% among pubertal boys (n=2179). Socio-economic status, indicated by type of school attended, was an important factor determining the risk of anaemia. Girls had a higher risk when they attended a poor school (OR poorest school, 1.00; other schools, 0.67-0.87), had reached puberty (OR, 1.25), had lower retinol intake (OR 1st-4th quartiles-1.00, 0.97, 0.89, 0.77) and higher vitamin A intake from plant sources (OR 1st-4th quartiles-1.00, 1.10, 1.31, 1.04). Boys had a higher risk of anaemia when they attended a poor school (OR poorest school 1.00, other schools 0.54-0.63), were younger (OR per year=0.79), had not yet reached puberty (OR not yet, 1.00; already, 0.78), were shorter (OR per cm 0.95), had smaller mid-upper-arm circumference (MUAC) (OR per mm 0.99) and lower retinol intake (OR 1st-4th quartile 1.00, 0.67, 0.74, 0.68). CONCLUSIONS: Anaemia in adolescents should be reported separately for pre-pubertal and pubertal subjects and for different ages, and the population's socio-economic status should be specified. The results of this survey call for treatment of anaemia in adolescents. Given Indonesia's current situation, micronutrient intake of adolescents should be increased using supplements for all girls and for pre-pubertal boys. SPONSORSHIP: This survey was funded by USAID through the OMNI project.     

Are there short cuts to pubertal assessments? Self-reported and assessed group differences in pubertal development in African adolescents.

PURPOSE: Self-rating of pubertal development using the Pubertal Development Scale (PDS) is recommended as a noninvasive assessment of puberty in large community-based surveys of adolescent development and behavior. The objective of this study was to assess the reliability of the PDS for the first time among urban, Black South African youth. METHODS: The concordance between adolescents' self-assessment of sexual maturation using the PDS and those of an expert rating by a trained health professional using the Sexual Maturation Scale (SMS) were determined in a group (n = 182; 49% female) of Black South African youth aged between 10 and 18 years recruited from schools in Soweto, South Africa. Furthermore, the concordance between adolescents' self-assessment of puberty using the PDS and a previously validated self-assessment technique using SMS was also determined in a large group (n = 1388; 53% female) of young adolescents aged 13 years old participating in a birth cohort from Soweto-Johannesburg. RESULTS: The convergent validity of PDS proved to be poor with several PDS items (facial hair, skin change, and growth) proving unreliable both within the school survey across the different age groups when compared to SMS (kappa coefficient of 0.34 for females and undetermined for males), as well as, within the cohort of 13-year-olds (kappa coefficient of 0.16 for females and 0.19 for males). CONCLUSIONS: The results suggest that there may be as yet undocumented differences in pubertal manifestations and awareness of these manifestations, especially facial hair and skin change (acne), among urban, Black South African youth that make the PDS self-assessment less reliable as a pubertal assessment tool in multiethnic community-based research.

Body mass index in children and adolescents according to age and pubertal stage

OBJECTIVE: To evaluate the dependence of body mass index (BMI) values on pubertal stage in subjects similar in age. DESIGN, SUBJECTS AND MEASUREMENTS: Height and weight were recorded cross-sectionally in school subjects from three provinces in central Italy. The subjects were subdivided into three groups: (1) 4271 school subjects (2125 males and 2146 females; 8.5-15.5 y old), in whom the pubertal development was also recorded, were selected to subdivide BMI values according to pubertal stage and age; (2) 6345 females (10.5-14.5 y old), who were asked whether or not they had had their first menstrual period, were selected to subdivide BMI values according to age in pre-menarche and post-menarche girls, separately; and (3) 1919 females (10.5-14.5 y old), who had presented their menarche within the previous 6 months, were selected to subdivide short-term post-menarche BMI values according to age. RESULTS: The medians and interquartile ranges of BMI varied according to age and pubertal stage. Kruskall-Wallis test performed in subjects similar in age demonstrated that significant differences existed among the medians of BMI values of subjects at different pubertal stages in 12-14-y-old males (P<0.05), and in 11-14-y- old females (P<0.001). The difference also proved to be significant between stage I and stage II (P<0.05) in 10-y-old females, but not in 10-11-y-old males. The Kruskal-Wallis test performed in subjects similar in pubertal stage demonstrated that significant differences among the medians of BMI at different ages existed only in females at stages II and III. A significant positive trend was observed in both genders according to pubertal stage for BMI values of subjects similar in age (z-test for trend, P<0.01). On the contrary, a negative age trend proved to be significant in females at stages I (P<0.01), II (P<0.01) and III (P<0.001), but not in males when the subdivision of BMI was made according to age in subjects similar in pubertal stage. BMI values were significantly higher in post-menarche girls as compared to pre-menarche girls similar in age (P<0.001). However, at partial regression analysis BMI values were influenced by pubertal stage and, to a lesser extent, by age, but not by menarcheal status. An inverse association between short-term post-menarche BMI and age was observed, with the highest values in girls presenting menarche at 11 y of age (P<0.05). The negative trend was demonstrated at the z-test for trend (P<0.001). CONCLUSIONS: BMI values depend on pubertal degree of maturation, especially in girls. This influence should be taken into account when BMI is evaluated in adolescents. Sponsor: University of Perugia, Region of Umbria.
