Healthy Growth and Development of the Adolescent



Healthy Growth and Development of the Adolescent

INTRODUCTION

Adolescents are human beings at crossroads. Their lives hang in the balance between childhood and adulthood. Myriad physical, psychosocial, and cognitive changes occur during adolescence. At the same time, adolescents live in a rapidly changing world that offers many challenges to their well-being. The primary care provider must appreciate the developmental changes that occur during adolescence to provide appropriate and timely advice regarding risky behaviors. The provider also must recognize and discuss the realities facing adolescents: early initiation of sexual activity; the commonness of sexually transmitted infections; the availability and addictiveness of cigarettes, drugs, and alcohol; and risks involved with motor vehicles, firearms, and other behaviors.


GROWTH AND DEVELOPMENT

Adolescence can be broken into three stages labeled early adolescence (typically ages 10–14), middle adolescence (ages 14–17), and late adolescence (ages 17–21). Physical, cognitive, and psychosocial changes define these stages. There is, of course, considerable variation, but using these stages as guidelines can aid in the approach to an adolescent patient.


Physical Development

Puberty is the term applied to the biologic processes that ultimately enable reproductive capacity. The changes of puberty can occur in as few as 2 to 3 years or may take as long as 6 to 7 years (Cronau & Brown, 1998). The physiologic changes of puberty are orchestrated by the hypothalamic-pituitary-gonadal axis. The hypothalamus releases gonadotropin-releasing hormone (GnRH) in a pulsatile fashion. GnRH stimulates the pituitary gland, nestled in the tella surca of the cranium, to release the gonadotropins: follicle-stimulating hormone and luteinizing hormone. These hormones signal the end organs, namely the ovaries, testicles, and adrenal glands, to release the hormones that foster secondary sexual characteristics. The hypothalamic-pituitary-gonadol axis is well developed at the time of birth. It is suppressed during most of early childhood, then is reactivated at the onset of puberty. The central nervous system controls the onset and progression of puberty.

Tanner, an English endocrinologist, described and outlined the usual sequence of physical changes in puberty. Most of these changes take place in early adolescence and are completed by middle adolescence. The defining sequence in girls is related to the breasts and pubic hair. In boys, the sequence is based on changes in the genitals and pubic hair. The Tanner stages, also known as sex-maturity ratings, help to predict other physical changes important to adolescents, such as the growth spurt, menarche, and spermarche. Tanner stage 1 is child-like, and Tanner stage 5 is adult-like.

In the female, the physical change that marks progression from Tanner stage 1 to stage 2 is the development of the breast bud or thelarche, which occurs on average at age 11. The growth spurt, defined by peak height velocity, occurs in girls between Tanner stages 2 and 3. Peak height velocity is recognized with the help of a growth chart. Menarche, or the beginning of menstruation, generally begins during Tanner stage 4 to 5. Thus, the clinician can reassure a 15-year-old girl at Tanner stage 3 who has not yet experienced menarche that there is no need for alarm.

In the male, the physical change heralding the onset of puberty is growth of the testicle. The immature testicle is less than 4 mL in volume, whereas the fully mature adult testis reaches a volume of approximately 20 to 25 mL. Testicle growth begins on average at age 12. The growth spurt in boys occurs between Tanner stages 3 and 4. Spermarche, or the first release of spermatozoa, does not occur before Tanner stage 3. Facial hair in males occurs only after Tanner stage 4 for pubic hair.


Cognitive Development

Cognitive development in the adolescent proceeds in halting steps. Jean Piaget had a strong influence on our understanding of adolescent thought processes. He used the terms concrete operational thinking and formal operational thinking to describe the transitions made in cognitive development from childhood to adolescence. Early to middle adolescents exhibit concrete thinking. Such thinking is oriented in the present. Concrete thinkers cannot think abstractly and have difficulty understanding the consequences of their behaviors. Formal operational thinking uses deductions, hypotheses, rules, and logic to solve problems. Middle to late adolescents are expected to exhibit operational thinking. Full abstract thought allows an individual to weigh the pros and cons of actions and to anticipate the future.



Psychosocial Development

Sigmund Freud’s general theory of psychosocial development provided Anna Freud, his daughter, with the framework
upon which she built her theory of adolescent ego development. Anna Freud described puberty as the trigger for a sudden surge of strong erotic and aggressive impulses; this is the foundation for the traditional psychoanalytic conception of adolescence as one of stress and tumult. Other studies of adolescent development have found less tumultuousness and anxiety in the teenage years.

Erik Erikson described the adolescent struggle as identity formation versus identity diffusion. Identity formation describes the adolescent’s attempts to answer the question “Who am I?” Identity diffusion is defined by an inadequate personal identity. Erikson’s interpretation of adolescent psychosocial development sheds light on the teenage years as a necessary time of experimentation with alternative roles and value systems.

The three stages of adolescence (early, middle, and late) have characteristic findings in terms of psychosocial development. Early adolescents struggle to begin to separate from their parents. They are conflicted in their desire for separation, swaying between demands for independence and requests for their parents’ assistance. In this struggle for independence, early adolescence is similar to toddlerhood. Early adolescents like to spend time alone. They are preoccupied with their rapidly changing bodies. A pimple may seem disastrous to the early adolescent, who feels “on-stage” and believes others to be just as preoccupied with his or her body. Early adolescents often spend time only with friends of the same sex. A common finding at school dances and parties is groups of boys and girls standing at opposite ends of the room.

Middle adolescents have begun to adjust to their external appearance. The peer group assumes importance as the adolescent further distinguishes the self from parents. Middle adolescents spend more time with their peers. They often dress and talk in ways that show the strong influence of the peer group. Conflicts with authority figures may occur. Dating can take place in groups, and romantic relationships have relatively short lives.

Late adolescents no longer have as strong a need for the peer group. They begin to form more adult-like relationships. They have adjusted to their body appearance and are less concerned about their peers’ opinions regarding clothing and activities. This is a time when the adolescent assumes more adult responsibilities and begins working toward vocational goals.



HISTORY AND PHYSICAL EXAMINATION

Table 12-1 provides critical foci for the history, physical examination, and health promotion or disease prevention of the adolescent.







History

Adolescent history taking can involve the adolescent alone or together with parents. Parents should feel welcome in the clinical setting, but it should be clear to all that the adolescent is the priority person. The clinician can reinforce this idea from the outset by introducing oneself first to the adolescent and addressing most questions to him or her. If parents are present, all should meet together at the beginning of the adolescent history.


Confidentiality

At this time, the provider should explain the concept of confidentiality to the adolescent and caregiver, who need to understand that questions regarding high-risk behaviors, such as sexual activity, can be discussed by the patient and clinician in confidence. Communicating this concept clearly is important for all so that the adolescent will be willing to share information. Most adolescents will not share sensitive information unless they are assured that such information is held in strictest confidence (Ehrman & Matson, 1998). Adolescents may better understand the terms “privacy” or “just between you and me” than the word “confidentiality” (Ginsburg, Menapace, & Slap, 1997). The provider must inform the adolescent and parents that the provider is obligated to inform the parents if the adolescent tells the provider of an intention to hurt himself or herself or others. The provider may find it helpful to have written pamphlets that describe the concept of confidentiality available in the waiting room.

The parent may be asked to provide information on family medical history and parts of the teen’s past medical history, of which the adolescent might not be aware. Parents also should be asked about any concerns they have regarding the adolescent’s health. The clinician can address the remainder of the history taking directly to the adolescent. Some health care settings use a written questionnaire to assess risk behaviors in adolescent patients. All questionnaires should be marked as confidential; ideally, a quiet, private area away from parents should be available for the adolescent to complete the form.


Parents who have difficulty separating from their offspring during the health visit may need to be reminded that individuation is a goal of adolescence. The health care visit is an opportunity for the teenager to practice independent interactions with an adult, whose goal is to guide the teen toward a healthy lifestyle. Most parents understand the teenager’s need for privacy and appreciate the chance for the adolescent to discuss confidential health care issues with another adult.

Laws regarding minors’ rights to confidentiality undergo continual modification. Medical conditions that may be treated without parental consent, depending on state law, include sexually transmitted diseases, human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome (AIDS), contraception, pregnancy, abortion, sterilization, substance abuse, and mental health. Providers should become familiar with the statutes of their own state regarding confidential services for minors. One resource is a publication entitled State Minor Consent Statutes: A Summary, prepared by the National Center for Youth Law (English & Matthews, 1995).

The relationship between confidentiality and payment of services is an important consideration. A parent’s discovery of an independent, confidential visit by means of a bill or insurance statement places both teenager and provider in very awkward positions. It may be impossible for the provider to promise full confidentiality unless services are provided for free or the adolescent can pay for the services. Referrals may be necessary if a payment issue precludes the clinician from providing confidential care. The clinician should be aware of area resources (such as federally funded family planning clinics) that base sliding fee scales on the adolescent’s own income.


Review of Systems

The review of systems (ROS) can be asked in a head-to-toe manner. Early adolescents, who are very attuned to the changes occurring in their bodies, often provide detailed and seemingly superfluous answers to ROS questions. Patience and attentive listening help the adolescent feel that the provider cares about what is happening to the teen. Sometimes questioning the early adolescent can be improved by using explanatory adverbs and adjectives. Instead of asking the 13-year-old if he or she has stomach trouble, the provider might ask more specifically: “Do you get frequent stomach aches that bother you a lot?”

The female adolescent’s ROS should include questions related to menstruation: age at menarche; frequency, length, and regularity of periods; and physical discomfort related to menstruation. An adolescent who reports dysmennorhea should be questioned as to what remedies she has tried, which remedies are beneficial, and if she misses school due to menstrual discomfort.

The ROS should include a general diet history and a review of sleep patterns. Growth requires energy and an adequate store of nutrients, yet adolescence is a time when diets are often irregular and loaded with “fast-foods” that have limited nutritional value. Screening for anorexia nervosa and bulimia nervosa also should occur at this time. The clinician should ask adolescents if they are happy with their body weight and if they have recently tried to lose weight. Females are at greater risk for eating disorders; however, some male athletes, such as wrestlers, may use drastic weight loss techniques to meet weight goals for their sport.

Adolescents also need to be screened for psychosocial problems in a standardized format. Studies have found such screening to be conducted sporadically for adolescent patients, with providers often avoiding emotionally sensitive issues (Elster, 1998). To address neglected areas, several different organizations have established guidelines for the adolescent visit. These include “Guide to Clinical Preventive Services” by the United States Preventive Services Task Force; “Guidelines for Adolescent Preventive Services” by the American Medical Association; “Age Charts for Periodic Health Examinations” by the American Academy of Family Physicians; “Bright Futures (BF): Guidelines for Health Care Supervision of Infants, Children, and Adolescents” by the Maternal and Child Health Bureau of the Health Resources and Service Administration; and “Recommendations for Pediatric Preventive Health Care” by the American Academy of Pediatrics. All these guidelines recommend screening regarding eating disorders, sexual activity, alcohol and other drug use, tobacco use, abuse, school performance, depression, and risk of suicide (Elster & Levenberg, 1997).

One method of organizing the adolescent interview to capture psychosocial data is to use the acronym HEADSSS (Reif & Elster, 1998). This is an adaptation of an acronym previously presented by Goldenring and Cohen (1988). The HEADSSS questionnaire encompasses all areas of screening recommended by the above organizations. It proceeds from less personal to more personal questions. Because many questions may be embarrassing to adolescents, it is often helpful to preface questions with a statement such as, “I know that some of these questions may be embarrassing, but I need to ask them to learn about your health.” Another way to introduce topics that are possibly threatening to the adolescent is by first asking the adolescent about the habits of peers. For example, when asking about substance use, the provider may start by stating, “A lot of teenagers experiment with drinking alcohol. Do any of your friends drink beer, wine, or other types of liquor?” After talking about friends’ habits, the adolescent may then feel more comfortable talking about himself or herself. The clinician should alter questions as necessary to obtain comfortably an accurate picture of how the adolescent is functioning within each of the psychosocial spheres designated by HEADSSS. Sample questions that could be used under each of the headings are as follows:



  • H—Home and family: Who lives at home? Is anyone ill? How do you get along with your family members? Are any guns in your home?


  • E—Education and school: Do you like school? What grade are you in? How were your grades on your last report card? How many days have you been absent so far this year? What are your plans after you finish high school?


  • A—Activities and associates: What things do you do on an average day after school? Do you participate in any sports? Have you ever been injured playing sports? Do you work? How many hours a week do you work? Do you drive? Do you wear your seat belt in the car? Do you have close friends that you hang out with?


  • D—Drugs, alcohol, and cigarettes: Do your friends or family members smoke? Some teenagers experiment with trying out different types of drugs. Have you tried smoking pot? Have you used inhalants, such as paint thinners and aerosol cans of whipped cream? Have you used crack or any other drug that could make you feel “high”? Have you tried using any kinds of drugs or dietary supplements to improve sports performance?



  • S—Sexuality and sexual activity: Do you have a girlfriend or a boyfriend? Have you ever had sex with a girl, boy, or either? Has anyone ever forced you to have sex? How old were you the first time that you had sex? How many partners have you had in the last 6 months? Do you use condoms always, sometimes, or never? Have you ever had a sexually transmitted disease?


  • S—Suicide and depression: Have you ever tried to hurt yourself? Do you often feel very sad? What do you do when you feel sad or very angry? Do you have someone that you can talk to when you are feeling down? A patient who reports any suicidal ideation needs to be asked specifics: Have you thought about how you would kill yourself? How easily could you accomplish this plan? Are you thinking about killing yourself in the near future? (Direct questions do not precipitate suicidal action and may allow the provider to intervene and save the life of a depressed adolescent.)


  • S—Safety, violence, and abuse: Do you feel safe where you live? Have you ever had a relationship with someone who tried to hurt you? Have you ever been abused?

The provider must assess the developmental and social experience levels of the adolescent and gear questions to specific needs. For example, a 13-year-old who giggles, looks embarrassed, and responds negatively when asked about ever having dated probably will not need an in-depth sexual assessment that focuses on condom use and number of sexual partners in the last 6 months. The adolescent’s negative response would, however, leave an opening for the clinician to assess the young adolescent’s knowledge of pregnancy, to encourage abstinence, and to discuss briefly STIs and their prevention.

Important communication skills for providers to develop are the nonverbal techniques of recognizing and expressing emotions and the ability to express verbally sensitivity to the adolescent’s feelings. Additionally, bidirectional communication, direct questions about psychosocial issues, and attentive listening to the patient’s responses improve the diagnosis and management of health problems and the patient’s satisfaction (Coupey, 1997).


Physical Examination


Approach to Examination

The adolescent physical examination can be approached in a head-to-toe manner with the exception of the genital examination, which is best left for last. Necessary tools for a complete examination include an ophthalmoscope, otoscope, blood-pressure cuff, and stethoscope. Other tools that may be needed include a scoliometer, magnifying glass, speculum, equipment for acquiring lab specimens, and a microscope. The examination is most easily accomplished with the adolescent undressed and wearing a gown. Some adolescents are very uncomfortable disrobing all at once. The clinician may allow the adolescent to stay dressed, removing one piece of clothing at a time as necessary for the examination to proceed.

Adolescents are concerned about disease transmission within the context of a physical examination. When ninth-grade students were interviewed concerning items that affected their decision to seek health care, the top two concerns were hand washing and the use of clean instruments. Students said that they wanted to see providers wash their hands and instruments removed from packaging (Ginsberg et al., 1997).


Sequence


Skin

The adolescent’s skin should be carefully examined for bruises, tattoos, rashes, and lesions. Acne lesions are common concerns. Acne is commonly caused by the shift in hormones that occurs at puberty but also may be exacerbated by stress (Johnston & Saenz, 1997). The skin should be observed for open and closed comedones, cysts, and degree of oiliness.


Eyes

The eye examination should include assessment of eye movement and fundoscopy. Pupillary dilatation or constriction should not be ignored because either could indicate drug use. The provider should look for signs of conjunctivitis and possibly conduct a vision screen.


Ears, Nose, and Throat

The ear examination involves checking the tympanic membranes for appearance and movement. An auditory screen may be conducted. For the nose, the provider should look for a deviated septum, allergic rhinitis, or nasal irritation that could indicate a drug-sniffing habit. The clinician should check for dental caries, pharyngeal lesions, malformations of the uvula, and normal opening of the jaw.


Nodes

A thorough examination of nodes, including the cervical, occipital, supraclavicular, axillary, epitrochlear, and inguinal, is conducted. Any enlargement of supraclavicular nodes that would require a chest x-ray to rule out the possibility of infection or malignancy should be noted.
