Childhood adversity data now available on Kidsdata

Big Family Kids Parents Grandparents Generation Illustration

Today, Kidsdata introduces a brand-new topic to our site, Childhood Adversity and Resilience. The release today coincides with the opening of the Conference on Adverse Childhood Experiences in San Francisco.

The new suite of data complements other Kidsdata topics such as Child Abuse and Neglect, Intimate Partner Violence, and Family Income and Poverty. It includes 56 indicators about the prevalence of adversity and resiliency among California’s children, among mothers of infants reflecting on their childhood, and, exclusive to Kidsdata, among California adults with children living in their homes reflecting on their childhood.

Specific childhood adversity indicators give us a picture of the prevalence of physical, sexual, and verbal abuse inflicted on California children, and exposure to violence, substance abuse, and mental illness. Kidsdata’s release today also includes data on child resiliency, or the ability to mitigate the effects of childhood trauma.

Childhood adversity, sometimes referred to as Adverse Childhood Experiences (ACEs), has come to be seen as an urgent public health crisis. The higher number of traumatic events a child experiences, the more long-lasting impacts those events may have on the child’s physical, mental, and emotional health. These events often lead to serious complications in adulthood, such as chronic diseases, substance abuse, and depression.

California-specific data were compiled from the National Survey of Children’s Health, the Maternal and Infant Health Assessment, and the Behavioral Risk Factor Surveillance System.

This new topic was made possible by a partnership between Kidsdata and the California Essentials for Childhood Initiative and its Shared Data and Outcomes Workgroup, as well as numerous organizations that provided data: Public Health Institute’s Survey Research Group, the California Department of Public Health’s Maternal, Child and Adolescent Health Program, the University of California, San Francisco’s Center on Social Disparities in Health, and the Child and Adolescent Health Measurement Initiative.

Today’s data release helps policymakers, researchers, social workers, and practitioners identify opportunities to prevent childhood trauma, allay its effects, and develop better community support systems that promote resiliency. While California has made strides in these areas, continued efforts are needed to ensure that all children thrive and reach their full potential.

Infant care in CA now costs as much as UC tuition

California parents are hit hard in the wallet not only when their kids head out to college, but also in the first two years of their children’s lives. According to the latest data on Kidsdata, the state’s parents spent an average of $13,327 per year to send their infants to a child care center in 2014, the same year that UC tuition and fees hit $13,222 (PDF). Nationally, childcare for children below age five has also exceeded that of in-state college tuition.

When broken down by county, Bay Area counties had the highest costs of infant care, with Marin County leading the pack at more than $18,000 per year, while more rural counties in far northern California and the central valley had the lowest costs for infant child care, at less than $12,000 per year.

Center-based infant care costs in California made up an estimated 14 percent of the median annual income for married couples and 45 percent for single parents in 2014. In 2014, California was ranked the 8th least affordable state for center-based infant care in the nation.

Despite the high costs of child care relative to income, nationally, the median hourly wage for child care workers is $9.77, and nearly half of this work force receives government assistance in the form of food stamps, welfare benefits, or Medicaid.

Early childhood is a critical period for cognitive, biological, and social development. The quality of children’s environments and experiences during these years can have lasting effects. From infancy, children are learning to relate to others and their environment while developing the skills to successfully navigate social, emotional, and educational challenges. Children who attend high-quality preschools tend to have better test scores, fewer behavioral problems, and higher rates of high school graduation, among other long-term benefits.

Policies that could improve child care include improving the state’s professional development infrastructure to prepare and support an effective early care workforce, making the Child and Dependent Care Tax Credit fully refundable at the state level, and encouraging other federal solutions to address the high cost of child care.

Bay Area family housing sees highest rent hikes in the state

Shattered candy bar in shape of house

Since the end of the Great Recession, California’s Bay Area counties have seen the highest rent increases in the state. For example, in Marin, San Francisco, San Mateo, and Santa Clara counties, the fair market rent for studios, one-, two-, three-, and four-bedroom housing units increased by more than 30 percent between 2009 and 2016, according to the latest data on Kidsdata.

Larger, family-sized housing units saw the greatest increases. In Alameda and Contra Costa counties, for example, three-bedroom housing units saw higher rent hikes than any other size unit. In Marin, San Francisco and San Mateo counties, four-bedroom housing units saw the highest rent hikes. In those counties, the fair market rent for a four-bedroom housing unit rose by 52 percent, from $2,339 in 2009 to $3,556 in 2016.

Stable, affordable, quality housing is linked to positive health outcomes for children. Families that spend more than half of their income on housing tend to spend much less than other families on essential items, such as food and health care. In some cases, a lack of affordable housing can result in families living in crowded households. Residential crowding may be linked to the prevalence of certain infectious diseases, poor educational attainment, and psychological distress, among other potential adverse effects.

Policy options that could improve housing affordability and promote the well being of children include preserving and increasing the availability of affordable housing, expanding housing trust funds, housing bonds, and California’s Low Income Housing Tax Credit, and reducing administrative barriers to receiving rental assistance.

CA Soda Taxes: Where could their impact be greatest?

California map outline with can of soda in center

Taxing soda is associated with decreased soda consumption, according to the first analysis of the impact of Berkeley, California’s 2014 soda tax. Published earlier this summer in the American Journal of Public Health, the study shows that after the tax was implemented, sugary beverage consumption fell by 21 percent in Berkeley, while water consumption rose by 63 percent.

Berkeley was the first city in the nation to levy a tax on soda. This fall, three more California cities—San Francisco, Oakland, and Albany—will consider such a tax on their November ballots. An effort to pass a statewide soda tax in California failed to gain steam earlier this year.

The latest data on children drinking sugary beverages in California are now available on Kidsdata. San Francisco and Alameda counties, home to the four cities that have passed or are considering passing soda taxes, had the lowest percentages (about one in five) of children drinking sugary beverages, among counties with data. In Yuba, Kern and Tulare counties, all in the central valley, three in five children drank at least one sugary beverage per day.

Statewide, in 2013-2014, two out of five children drank one or more sugary beverages per day. Among the youngest children, those between 2 and 11 years old, the gap between ethnic groups is large. More than half of young black children drank sugary beverages per day, compared with one-third of young Latino and Asian children and one-fifth of young white children.

Children should minimize consumption of sugary beverages, which are linked to poor health outcomes, including unhealthy weight gain and obesity. Experts suggest promoting cross-sector, comprehensive strategies to reduce consumption of sugary beverages and increasing the availability of healthy, affordable food and beverage options for children and families, particularly in low-income communities.

CA schools face acute shortage of nurses and counselors

Child getting throat exam in school

California public schools are falling woefully short when it comes to student support personnel. The American Academy of Pediatrics recommends a ratio of one school nurse to 750 students. According to the most recent data available on Kidsdata, however, the state’s public schools employed one full-time nurse for 2,784 students in 2015, or nearly four times the recommended ratio. For the 52 counties with available data, none met the recommended ratio. Yuba County had the most impacted ratio by far, at one nurse for nearly 14,000 students.

The state falls behind in other support categories, too. The American School Counselor Association recommends a ratio of one school counselor to 250 students, yet California’s ratio was one to 792 students in 2015, or more than three times the recommended ratio. Rural counties such as Lassen, Calaveras, and Plumas had the most pronounced ratios, at one counselor for more than 1,400 students. In 2014, California ranked 49th in the US (PDF), after Arizona, in its counselor-to-student ratio.

Student support personnel address students’ social, emotional, behavioral, physical, and cognitive needs to help them reach their maximum academic and health potential. Schools that provide students with greater access to nurses and counselors are associated with more positive school climates, which generally lead to better student performance.

Policy options that could improve student access to quality support services include maximizing partnerships and existing funding streams (PDF) to ensure that students have access to school counseling and other mental health services, promoting the delivery of health care services at school by funding school nurses and school-based health centers, and integrating student mental health and health care services into a coordinated and comprehensive system of supports.

CA’s new vaccine law: which counties have yet to achieve herd immunity?

Cartoon Crowd, Shield Ring

Last month, California’s new mandatory child vaccination law, SB 277, took effect. The law helps enforce the Department of Education’s requirement that all California children attending public and private schools receive a series of vaccines, unless they have a medical exemption. Inspired by the 2014 measles outbreak at Disneyland and the state’s 2010 and 2014 whooping cough outbreaks, SB 277 prohibits parents from citing personal beliefs or religion as reasons to not vaccinate their children.

To better understand how SB 277 will affect the health of children in California, Kidsdata has released the newest data available on student immunizations for the 2015-2016 school year. Depending on the effectiveness of the vaccine, and how long immunization will last, California public health officials recommend vaccination rates of between 80-94 percent in order to achieve community immunity (PDF), also known as “herd immunity.” Diseases such as polio, which is less contagious, have a lower threshold, while diseases such as measles, which is highly contagious, require a 94 percent threshold in order to protect those most at risk.

Between 2011 and 2016, the state showed a modest 2 percent rise in the percent of kindergartners who had all required immunizations, reaching 93 percent in 2016. When broken down by county, however, geographic differences become clear. At 100 percent, Sierra County led the 26 counties with immunization rates of 94 percent or higher. Three counties had rates lower than 80 percent: Tuolomne, Nevada, and Trinity.

The Gold Country counties of Sierra, Calaveras, and Mariposa each saw a rise of at least 8 percentage points since 2011, bringing them closer to recommended thresholds. On the other end of the spectrum, Amador, Modoc, and Trinity Counties (one in Gold Country, and two in California’s far north) all saw drops of at least six percentage points, moving their populations further from community immunity.

Immunizations are among the most successful and cost-effective preventive health care interventions, helping millions of children in the U.S. and internationally avoid contracting numerous serious and potentially fatal infectious diseases.

How safe are black children in California?

“It’s okay, I’m right here with you.” These were the soft-spoken words of four-year-old Dae’Anna Reynolds, just minutes after she and her mother had witnessed the July 6 police shooting death—while sitting in the same car—of Philando Castile in Falcon Heights, Minnesota. The Castile case, along with the police shooting deaths of black children such as Michael Brown and Tamir Rice, are reminders of the disparate levels of violence faced by black children in this country.

To better understand how safe black children are in California, Kidsdata provides a wealth of relevant data, broken down by race. In multiple categories, black children consistently face the worst outcomes when compared to children of other ethnicities: black and multiracial infants under one year old are dying at a high rate and black children and youth over one year old are also dying at a high rate.

The disparity in infant mortality rates is largely attributed to perinatal conditions and sleep-related incidents, but for children over the age of one, additional factors include death from violence committed by parents/caregivers as well as by non-parents/caregivers.

In school, data on Kidsdata show that a high percentage of black students report being bullied because of their race, compared to students of other races; and a high percentage of black students report feeling unsafe at school, compared to students of other races.

Last month, Sacramento County announced a $26 million initiative to address its high rate of black child deaths. Working with the Steering Committee on Reduction of African American Child Deaths, the program’s goal is to organize community groups, engage policymakers, coordinate existing services, and push for data-driven accountability in order to reduce black child mortality by 10-20 percent by 2020.

Child asthma hospitalizations drop as CA’s air quality improves

The rate of asthma-related child hospitalizations in California dropped by one-third, from 16 to 11 percent, between 2001-2014, according the most recent data now available on Kidsdata. During the same time period, measurements of air quality also improved: the number of days with ozone levels that exceeded regulatory standards in California dropped by 60 percent, and the levels of Particulate Matter Concentration fell by 23 percent.

Five counties, Napa, Ventura, Imperial, Yuba, and Yolo, all saw drops of more than 50 percent in total asthma-related child hospitalizations.

Asthma is one of the most common chronic diseases among children in the U.S. and a leading cause of hospitalizations and absences from school. Environmental factors, including air pollutants, account for an estimated 30 percent of the total childhood asthma burden in California, according to a report by the Public Health Institute.

Children are more vulnerable to pollutants because they breathe more air relative to their size, compared to adults, and thus experience greater proportionate exposure to chemicals. In addition, children are at greater risk of harm from contaminants because their bodies and organs are not fully developed.

According to experts, policies that could influence asthma rates, treatment, and health consequences include ensuring that all children have adequate health care and insurance coverage for prevention and treatment of asthma. Other recommendations call for strengthening and enforcing laws and regulations limiting vehicle emissions, agricultural practices that generate dust and particulates, and industrial practices that generate air pollution.

California students getting fitter with age?

According to multiple 2015 data sets now available on Kidsdata, California students are showing improved fitness outcomes as they age. First, more students are able to meet physical fitness standards as they rise between 5th, 7th, and 9th grades. In 2015, 26 percent of the state’s 5th graders met all fitness standards, compared to 33 percent of 7th graders and 38 percent of 9th graders. The upward trend was consistent across all races and ethnicities.

Second, younger students showed higher rates of obesity compared to older students. In 2015, 40 percent of 5th graders were overweight or obese, compared to 39 percent of 7th graders and 36 percent of 9th graders.

Overweight and obese children are at higher risk for a range of health problems, including heart disease, stroke, asthma, and some types of cancer; they also are more likely to stay overweight or obese as adults. In addition, children with obesity are at increased risk for joint and bone problems, sleep apnea, and social and emotional difficulties, such as stigmatization and low self-esteem.

The Physical Activity Guidelines for Americans and the American Academy of Pediatrics recommend that children and adolescents participate in moderate-to-vigorous exercise at least 60 minutes every day. However, according to a 2014 report (PDF), only about one quarter of youth nationwide get the recommended amount of exercise.

According to experts, policy options that could improve children’s physical activity include ensuring that all schools meet state physical education requirements, making school recreational facilities available for use outside of school hours, and encouraging child care and after-school programs to incorporate physical activity opportunities. Additional recommendations that would reduce childhood obesity include providing access to affordable healthful foods and beverages, and reducing access to high-calorie and sugar-sweetened drinks and foods.
