Children Are Healthy
Good health provides an
important foundation for children and youth, helping them to focus on
school and other activities and nurturing their development. Access to
health insurance, either private or, like Medi-Cal, publicly funded, is
perhaps the most important indicator of the healthfulness of a
community's youth and children. Although precise numbers are impossible
to obtain for this measurement at the County level, the UCLA California
Health Interview Survey, (CHIS), reports that more children and youth
in Yolo County have access to health insurance than does the average
Californian aged 0-21. (Note that the survey sample for Yolo County is
relatively small and may therefore under or overstate the true number
of insured county residents. Given the importance of access to health
insurance, the community may wish to more thoroughly study this issue
in Yolo County.)
The need for regular healthcare
for children begins with the first trimester of pregnancy. In spite of
the importance of early prenatal care, only 65% of mothers in Yolo
County receive what is considered to be adequate prenatal care.
Nevertheless, fewer babies in Yolo County are born with low birth
weight. Low birth weight is associated with health risks and problems
for children.
Two current health concerns for
children are asthma and obesity. Asthma is an increasingly prevalent
disease in children that affects the respiratory system, but regular
access to health care and treatment can help control the symptoms and
reduce the need for hospitalization. Higher numbers of children and
youth with health insurance may be related to the relatively low levels
of hospitalization for children and youth with asthma in Yolo County.
Children and youth in Yolo
County appear to have fewer problems with their weight than children
across the state, but the percentage of obese children is still far
higher than the national goal of 5% or less of the child and adolescent
population. According to the California Healthy Kids Survey, over 10%
of children in grades 7-11 can be considered obese by their score on
the body mass index. Being obese or overweight is strongly correlated
with the occurrence of other health risks and diseases.
Preventative health care is
considered preferable to disease treatment, and required immunizations
have greatly improved children's health. Immunization levels in Yolo
County are close to the state averages, and in some cases higher.
Kindergarteners have much higher immunization rates than 7th graders in
2002, which may indicate that immunization rates among children have
been rising over time.
Teenagers often pose the
greatest risk to their own health by engaging in risky behaviors like
unprotected sexual activity, drinking alcohol, or smoking. Although
Yolo County teens report they are aware of the risks of smoking
cigarettes, this has apparently not completely ended teen smoking and
almost 30% of 11th graders report having smoked a cigarette at least
once in their lives. However, few Yolo County teens report smoking on a
regular basis. Yolo County teens also have a much lower incidence of
sexually transmitted diseases such as chlamydia and gonorrhea relative
to the state average.
We know that children's mental
health is as important as physical health in affecting their well
being. While Yolo County children and youth do not report higher levels
of depression than their peers statewide, the number of students
reporting sad or hopeless feelings for a period of at least two weeks
apparently increases as students move up from grade 7 to grade 11.
Children with health and dental
insurance coverage
Why is this important?
Because of the high cost, access
to health care is heavily influenced by health insurance coverage.
Because individuals with health insurance coverage are more likely to
receive preventative care, such as routine checkups, than are people
without health insurance, increased health insurance coverage in a
community can lead to improved quality of life and lower overall
healthcare costs.

The Immunization Branch of
the
California Department of Health Services oversees a statewide network
of local immunization registries, which are responsible for ensuing
that children receive immunizations. Yolo County is served by the Shots
for Tots Regional Coalition, a liaison between providers,
public agencies and parents. Children can be exempted from receiving
required immunizations for medical concerns, or personal or religious
beliefs; these exemptions are a small percentage of total missed
immunizations, but are increasing, particularly among children in
private school, according to the California Department of Health
Services.
The percent of Yolo County
kindergarten entrants and children in childcare with all required
immunizations is essentially equal to the state average, around 92%.
However, this still falls slightly short of the national Healthy People
2010 goal of 95% of children in childcare or kindergarten/first grade.
Immunization levels for 7th graders
were much lower than those for kindergarteners in 2002. As the
immunization requirements for 7th graders are not much higher than for
kindergartners, this may indicate a cohort of children in the 1990s
that did not receive all necessary immunizations, and thus current
higher immunization levels may be the result of recent improvements in
immunizing kindergarteners. A retrospective study of Yolo County two
years olds in 1994 revealed that only 60% were up to date in their
immunizations. Those two year olds are now just a few years younger
than the 7th graders in the 2002 data, only 80% of whom have received
all required immunizations.
Prenatal care
Why is this important?
The level of prenatal care
received is an important predictor of the future health of a
child. Adequate prenatal care is defined as care initiated by the
fourth month of pregnancy, followed by the mother receiving 80% or more
of the prenatal care visits recommended by the American College of
Obstetricians and Gynecologists.
 |
|
How is Yolo County doing?
Nearly 15% fewer
mothers in Yolo
County get prenatal care in their first trimester compared to the state
average. Yolo County is also far behind the national Healthy
People
2010 goal of 90% of live birth babies receiving prenatal care in their
first trimester, and 90% of live birth babies receiving adequate
prenatal care (dotted line on graph). Only 65% of Yolo County
mothers
from 1999 to 2001 received adequate prenatal care. A study of
Yolo
County children found that factors contributing to less than adequate
prenatal care are having low income, being of foreign birth, and
switching health care providers once or more during pregnancy.

Low birth-weight babies and infant
mortality rates
Why is this important?
The proportion of children
with low birth weight (5.8 lbs or less) is generally considered a
predictor of future health problems including infant mortality, and
increased special education usage.
|
|
 |
 |
|
How is Yolo County doing?
During the past 12 years
(1990-2002), fewer Yolo County children were born with low birth
weights relative to the state average, although the county’s rate of
low-weight births is still somewhat higher than the national public
health goal of 5%.
Yolo County’s rate of infant mortality has been somewhat lower than the
state average during the past 5 years, although during the two most
recent years, 2000 and 2001, infant mortality rates have been somewhat
above the state average.

Rates of asthma
Why is this important?
Asthma, a chronic inflammatory lung
disease, is the most common chronic disease among children, and one of
the leading causes of hospitalization and death among children.
The exact causes are unknown, but both genetics and environmental
triggers contribute to the development of asthma. Asthma symptoms
range from mild to severe, and although the disease cannot be cured, it
can be treated and controlled through proactive effort. These
efforts to control the disease in children can reduce risk of
hospitalization or death and lower later costs of treating the
disease. Without ready access to healthcare, children with asthma
are more likely to be hospitalized for the disease.
How is Yolo County doing?
There is no definitive
source of data regarding asthma prevalence in California, however the
California Department of Health Services reports asthma affects between
8% and 12% of the population. Yolo County has a higher rate of
lifetime asthma diagnosis compared with the state as a whole, according
to the California Healthy Kids Survey.
Long term increased levels of allergens and air impurities are known to
exacerbate asthma symptoms, according to the California and U.S.
Departments of Health Services. According to the California Air
Resources Board, although Yolo County air levels of pollutant
particulate matter are decreasing, the average number of days each year
that levels of suspended particulate matter, or “PM10,” are above state
standards is higher than surrounding counties. Suspended
particulate matter is inhalable particles in the air consisting of
metals, soot, soil and dust. From 1989 to 2000 Yolo County had an
average of 63 days where PM10 levels per 24-hour period were above
state standards, whereas Sacramento County had 57, and Solano County
only 21.
In spite of the poorer air quality, asthma hospitalizations for Yolo
County children are half the state average, around 9 per 10,000.
The Healthy People 2010 goal for asthma hospitalizations rates is 25
per 10,000 for children under five, and 7.7 for children and
adults. Although Yolo County data is not available in those age
categories, the county appears to be doing very well.

Incidence of obesity
Why is this important?
Childhood obesity is a top
concern with health officials, families and communities across the
country. The increase in childhood obesity is often associated
with an
increase in other adverse health conditions, such as type II diabetes
and hypertension.
How is Yolo County doing?
Obesity is determined as a
body mass index (BMI, the ratio of weight to height per age and gender
standards) above the 95th percentile. Individuals measured above
the 85th percentile are considered at risk of being overweight. (Note)
|
|
 |
The graph above shows how unhealthy
body weight in Yolo County youth has changed over time as compared to
the state average, rising slightly since the 1998-1999 school year to
35% of the student population having unhealthy body compositions.
Chart 1, shows a recent comparison of Yolo County youth and the
statewide average, indicating that in general fewer children in Yolo
County are overweight. Yolo County students, particularly in the
fifth and ninth grades, tend to be in better shape than the state
average. Chart 2 shows the proportions of children in Yolo County
who are overweight, or at risk to become overweight based on BMI from
self-reported height and weight measures. Although this data was
derived from self-reported measures of height and weight, the anonymity
and confidentiality of the survey increase the likelihood that the
measures are accurate.
The Healthy People 2010 goal is for no more than 5% of the child and
adolescent population to score above the 95th percentile in the body
mass index. Yolo County has not achieved that goal, with 12-13%
of surveyed students scoring above the 95th percentile.

Tobacco use among youth
 |
|
Why is this important?
Smoking is associated with
increased rates of serious diseases, such as lung cancer, high blood
pressure, and heart disease. It is one of the leading causes of death
among Californians. According to the Campaign for Tobacco-Free Kids,
90% of adult smokers started smoking at age 18 or younger. In
fact, most tobacco users begin smoking at age 13. Thus, efforts
aimed at lowering or eliminating teen smoking are crucial to reducing
rates of smoking as today’s youth become tomorrow’s adults.
How is Yolo County doing?
Yolo County has programs
to help teens quit smoking at Davis High School, River City High
School, and in Woodland schools. Peer education groups are one
effective way to help students fight nicotine addiction. High
levels of students (94-97%) reported knowing that frequent cigarette
use is dangerous.
The data indicates that there are fewer youth smokers in Yolo County
compared to the state. For both indicators, more boys than girls
in Yolo County reported having used tobacco, except in the 9th grade
when more girls report tobacco usage.
By the 11th grade,
less than 30% of Yolo
County students reported having ever smoked a cigarette. The
percent
of students who have ever used tobacco is much higher than the percent
of students who report having smoked tobacco daily in the last 30 days.
Just over 2% of Yolo County 11th graders report smoking cigarettes
daily. Approximately half as many 9th and 11th graders in
Yolo County
report smoking cigarettes as compared to youth across the state.

Youths with sexually transmitted diseases
Why is this important?
| Teens are at
greater risk of contracting
sexually transmitted diseases (STDs) than other age groups for a
variety of reasons: more sexual partners, less use of condoms, lack of
knowledge about diseases, difficulty accessing confidential health care
services, or difficulty obtaining contraceptives. Teens are much
more
likely to contract either chlamydia or gonorrhea than older sexually
active adults, and girls are at an even greater risk of contracting an
STD due to the nature of their physiology. |
|
 |
Because many sexually transmitted
diseases do not produce symptoms in infected individuals, they can go
unnoticed for a long time, with significant health effects. STDs
can harm the reproductive system of the infected person, affect fetal
health, and cause cancer or even death.
How is Yolo County doing?
Fewer Yolo County
youth have
contracted the STDs chlamydia and gonorrhea compared to the state
average, although gonorrhea rates increased somewhat in the late 1990’s
before subsiding in 2001. The number of teens with chlamydia has stayed
fairly constant since 1997. Yolo County has not reached the
Healthy People 2010 goal of only 19 new cases of gonorrhea per 100,000
people, although the county is well under the national goal of 3,000
cases per 100,000 adolescents and young adults (ages 15-24) infected
with chlamydia.
The mental health of children and youth
Why is this important?
The Healthy People 2010 goal is to
increase the proportion of children with mental health problems who
receive treatment. The Surgeon General's report and extensive research,
including projects sponsored by the National Institute of Mental Health
(NIMH), have demonstrated that anxiety and mood disorders, ADHD, and
conduct disorders interfere with children's normal development and
contribute to impaired learning, high rate of suicide among youth,
violence, and pose a risk for adult psychopathology. A recent national
survey revealed that while more than 10% of children in California have
serious behavioral problems, only a fraction of those children actually
receive mental health services and that California lags behind the rest
of the nation in the percentage of those children who do receive needed
mental health services.
How is Yolo County doing?
For the past 5 years, a higher
percentage of children and youth in Yolo County have been served by
County Mental Health Services compared with the state. Historically,
across the state and in Yolo County, Children's Mental Health was a
minor division in the overall mental health area. However, since 1997
resources such as entitlements for Early Periodic Screening Diagnosis
and Treatment (EPSDT), grants, mandates and new state allocations have
increased mental health funding for children, thus substantially
increasing the number of children served by County Mental Health
Services. In collaboration with community based partners and other Yolo
County departments serving children, the Children's System of Care
(CSOC) Division has increased access and provides better continuity of
care to eligible children and their families. In addition, services
have moved beyond the clinics, and staff are integrated into the
community in agencies like the schools, Child Welfare, Probation,
Juvenile Hall, Unified Family Court and Family Resource Centers so
families have access to a mental health practitioner at the same time
as they are engaged with other service systems. CSOC serves mostly
Medi-Cal beneficiaries who meet "Medical Necessity" criteria including
foster children, children with special health care needs, and children
eligible for benefits under the Americans with Disabilities Act (ADA).
Children included under a variety of other mandates, or who fit the
target population, are also served. No data is available for the number
of Yolo County children needing services, or for those children
receiving mental health services privately.
Adolescence is an emotionally volatile time for most young people,
making them particularly susceptible to depressive illness, which
causes them to withdraw from the activities of daily life - such as
school and sports - increases the risk of self-injury - including
suicide - and increases susceptibility to substance abuse. However,
Yolo County youth do not report higher than average levels of mental
illness, according to the California Healthy Kids Survey which asked
students in grades 7, 9 and 11: "During the past 12 months, did you
ever feel so sad and hopeless almost everyday for two weeks or more
that you stopped doing some usual activities?" As in the case of the
State, the number of Yolo County youth reporting sad or hopeless
feelings, that may be interpreted as symptoms of depression, increased
by age.
