Background: Adolescence marks the beginning of transition between childhood and adulthood. However, inadequate knowledge about this transition remains a challenge among this group.
Objective: This study was therefore designed to investigate the knowledge of puberty, sexually transmitted infections (STIs), and sexual behavior among very young female adolescent students aged 10-14 years in Agbor metropolis, Nigeria.
Methods: A qualitative and quantitative cross-sectional study was conducted among female adolescent students (10-14 years). The discussants were grouped into ages 10-12 years and 13-14 years. A total of four focus group discussions were conducted among the two groups in two government secondary schools in the study area, while a semi-structured questionnaire which comprised sociodemographic characteristics, knowledge of puberty, STIs, and sexual behavior was used to collect the quantitative data. The qualitative data were analyzed thematically for themes and content, while the quantitative data were analyzed using SPSS Version 15.0.
Results: The result shows most of the respondents 96 (97.0%) have heard of puberty and were able to define puberty 82 (85.40%). Furthermore, majority of the respondents have heard of the word human immunodeficiency virus 95 (96.0%) and STI 60 (60.6%), but few 4 (4.0%) have heard of the word contraceptive. In addition, only 12 (12.10%) of the respondents have a boyfriend, out of which only 3 (3.0%) have had sex at the age of 9 and 11 years, respectively.
Conclusions: The results shows some of the respondents are already sexually active at that young age, therefore more intervention programs targeting these group of students should be carried out regularly in schools nationwide.

| Introduction|| |
Adolescence is the most important period of human life as it marks the beginning of transition between childhood and adulthood. Globally, there are about 1.2 million adolescent in the world today, 90% of these adolescent lives in the lower and middle income countries and are between 10 and 19 years, 15% of this population are between 10 and 14 years, often referred to as very young adolescent. 
This transition between childhood and adulthood usually set the stage for future sexual and reproductive health outcome. Thus, this transitional stage is often critical as these younger ones are faced with profound biological, emotional, and social changes associated with the passage through puberty. , Menarche, the onset of menstruation in girls remains a challenge as they are uninformed, unprepared, and lack advice on how to manage their monthly menstrual period. These young female often times hide the onset of menses from others, missing school due to fear of a shameful menstrual leak.  Evidence has demonstrated lack of understanding on how menstruation occurs, how menstruation relates to fertility and when to calculate and expect their monthly period. 
For instance, in a study conducted across four African countries, only between 17% and 31% of female adolescents aged 12-14-year-old were able to identify and report experiencing their menstruation. ,,,
This transitional stage could be as devastating as girls at this stage of sexual maturation feel afraid, ashamed and confused most times.  Furthermore, girls see parents, mostly mothers as primary source of information and support during this transitional stage but most parents are not equipped to address issue relating to puberty.  Thus, leaving most of these young adolescents to obtain information on their reproductive health to peers and friends, who in turn may not have adequate knowledge on sexual and reproductive health.  Consequently, most of these adolescents grow up to engage in early sexual activity and risky sexual practices including unprotected sex with multiple partners. For example, in a study conducted at Ile-Ife South Western Nigeria on male adolescents aged 15-19 years and found that 76% of the secondary school youths had been sexually active within the past 12 months, 5% with prostitutes and 56% with more than one partner, but that only 8% had used a condom during that year.  Subsequently, some of these adolescents will grow up to account for a high proportion of sexually transmitted diseases including human immunodeficiency virus (HIV) in the country. 
Furthermore, studies still show sub-optimal 7% and 44%, level of knowledge of symptoms of sexually transmitted infection (STI) for men and women, among adolescents aged 15-19-year-old. In addition, research also confirms that many young people participate in risky sexual activities including early debut of sexual activities, multiple sexual partners, low and inconsistent use of condoms. ,, Similarly, most of the previous studies focused more on adolescents aged 15-19 years, thus leaving a gap among the very young adolescents 10-14-year-old. Furthermore, this age group has being overlooked in most sexual and reproductive health programs yet this group of females face health challenges with little or no knowledge about puberty, sexuality and reproduction. There is a need to access the knowledge of very young female adolescent student on puberty, STIs, and sexual behavior. Thus, this study was designed to determine the knowledge of puberty, STIs, and sexual behavior among very young female adolescent students' 10-14 years in Agbor metropolis, Nigeria.
The sociocultural environment logic framework  was adapted for this study to explain the relationship among the variables. The theory includes the determinants of sexual behavior which includes age, knowledge of puberty, HIV, and STI, having a boyfriend or friends that have boyfriends. Consequently, the immediate behavioral outcome is safe sexual behavior. The health outcome will be healthy youth and population.
| Materials and Methods|| |
This study is a descriptive cross-sectional survey using both qualitative and quantitative method of data collection. The study focused on very young female adolescents (10-14 years) in two government secondary schools; Dein Secondary School and Ime-Obi Secondary School, Agbor, Delta State.

The study focused on very young female adolescents in two government secondary schools. Dein Secondary School and Ime-Obi Secondary School, Agbor, Delta State.
The study focused on very young female adolescent students in junior secondary school (JSS) 1-3 between 10 and 14 years of age.
Female adolescents below 10 years and above 14 years were not included in the study. Senior secondary class were not also included in the study.
Sample size determination
For the quantitative study, a sample size of 100 was calculated using the formula for sample size determination for single proportion; while a total of 20 students from both schools were used in generating the qualitative data.
There are six government secondary school in Agbor metropolis which are Ogbemudein Secondary School, Agwu-Ewuru Secondary School, Iwu-Iyase Secondary School, Dein Secondary School, Agbor Technical Secondary School and Ime-Obi Secondary School. A random sampling through balloting was used to select two schools namely Dein Secondary School and Ime-Obi Secondary School. Four focus group discussions (FGDs) were used to obtain the qualitative data. Two FGDs with five respondents each were conducted between respondents of ages 10-12 years in Dein Secondary School and Ime-Obi Secondary School while two FGDs with five respondents each were conducted between respondents of ages 13 and 14 years in Dein Secondary School and Ime-Obi Secondary School. Purposive sampling was used to select the respondents in the FGDs.
Furthermore, random sampling technique was used to collect the quantitative data, 50 students from each school were randomly picked in the classroom. Students in JSS 1-3 were used for the study because most of the students in the age bracket of 10-14 years are usually in these classes in public secondary schools which were used for the study. Students in each of the classes were asked to stand and those students within the age bracket were randomly selected and given questionnaire to fill. The filled questionnaires were immediately retrieved from the respondents after filling. A total of 100 questionnaires were distributed but only 99 were retrieved giving a response rate of 99%. Both the FGD and the questionnaire distribution were done concurrently so as to prevent those that took part in the FGD from partaking in filling the questionnaire.
Instruments for data collection
Data collection in the study was carried out using FGD guide which was adapted from save the children formative research guide on very young adolescent girls and a semi-structured questionnaire which was developed. The FGDs was carried out among very young female adolescent student using a FGD interview guide. The FGD was conducted to assess respondent's knowledge on differences between sexes, fertility awareness, romance and sexual attraction, while a semi-structured questionnaire was self-administered to obtain information on the respondent sociodemographic characteristics, knowledge of puberty, STIs, and sexual behavior.
Data collection technique
The participant consented to the use of tape recorder during the FGD. The use of a voice recorder allowed the capture of their responses clearly during the discussion. The questionnaire administered were monitored properly and ensured that questions were read out for easy understanding since they are very young adolescent.
To ensure the validity and reliability of the instrument, the qualitative guide was pretested in Amai Mixed Secondary School. Cronbach alpha test reliability was used to determine the reliability of the instrument. The Cronbach alpha reliability statistics gave 0.703. Data generated were analyzed using SPSS version 15.0 (IBM Corp., Chicago, USA). Descriptive statistics were used to evaluate frequency distribution, while Chi-square test were performed to test for the association between variables of interest with level of significance set at P < 0.05.
Ethical approval for the study was obtained from the Department of Public and Community Health, Novena University Ethical Committee. In addition, an official approval for the study was given by the principal of Ime-Obi and Dein Secondary School, Agbor Delta State, respectively.

| Discussion|| |
The study shows most of the respondents 96 (97.0%) have heard of puberty and were able to define puberty 82 (85.40%). Furthermore, majority of the respondents have heard of the word HIV 95 (96.0%) and STI 60 (60.6%), but few 4 (4.0%) have heard of the word contraceptive. In addition, only 12 (12.10%) of the respondents have a boyfriend, out of which only 3 (3.0%) have had sex.
The findings shows most of the respondents have heard of puberty and were able to list signs of puberty in girls. This finding is similar to a study in Calabar where 90% of the students were knowledgeable of puberty  and also similar to a study conducted across four African countries of Burkina Faso, Ghana, Malawi and Uganda where adolescents were able to list signs of puberty among boys and girls. ,,, Furthermore, however, the Focus Group Discussions shows most of the respondents could not properly define menstrual cycle and when a woman is most likely to get pregnant during her menstrual cycle. This finding is similar to previous studies. ,,,
In addition, in the National HIV/AIDS and Reproductive Health Survey,  80% of males and 62% of females age (15-49) are aware of condom as a type of contraceptive. However, only few of the respondents have heard of contraceptive; but more than half believes use of condom can prevent pregnancy and diseases. This is similar to previous study which reported high awareness of condom use among adolescents. ,
Naturally, girls see parents, mostly mothers as the primary source of information and support during adolescent stage but most parents are not equipped to address issue relating to puberty.  A significant proportion of respondents in the FGD conducted claim to discuss issues of puberty with their mother and friends. This was further corroborated by the quantitative study were almost half and one-fourth of the respondents sources of information on puberty were from school and parents, respectively. This is in line with a study conducted in Pakistan where a small group of female adolescents reported getting information from parents or guardian.  Parent's communication with their adolescent girls has been reported to be important because sexual activity usually begin at this stage. , Thus, parents especially mothers should be empowered and encouraged to communicate with their adolescent girls who may receive inaccurate and contradictory messages about puberty, menstruation and sexual experimentation that can misguide them in the pursuit of better and safer reproductive health.
Furthermore, majority have awareness of the word HIV and STI. This finding is similar to a previous study which reported significant awareness and knowledge of HIV and STI among in-school adolescent girls in Kano, Northern Nigeria. 
Sexual behavior and relationship experience shows some of the respondents have had sex at that young age. This finding is similar to the study in Kano where few sexual activities was reported among female in-school adolescents.  This relationship of sexual activity and some independent factors was further highlighted as there was a significant association between respondents who had a boyfriend, respondents that have been kissed or romanced before, respondents who have close friends that had sex prior to the study and respondents who had ever had sex (P = 0.00). This shows having a boyfriend or being kissed or romanced and having friendship with peers who are already sexually active might influence the sexual activity of adolescents. 
Limitation of the study
Findings in this cross-sectional study conducted in two schools in Agbor Ika LGA, may not represent the knowledge and sexual behavior of all in-school adolescents nation-wide. Information bias from respondents may not be totally excluded as the authors depended solely on the responses provided by the respondents in both the qualitative and quantitative methods.
| Conclusion|| |
Respondents demonstrated awareness and knowledge of puberty, HIV, and STIs; however, some are already sexually active; therefore, more intervention programs targeting these group of adolescents in schools should be carried out regularly as these group marks the beginning of the transition from childhood to adulthood and every choice they make concerning their sexual behavior will go on to affect their lives as adults.
