Once the law goes into effect, individuals who do not
have minimal essential coverage will be required to
pay a tax penalty. e penalty will be waived if the cost
of coverage exceeds 8 percent of family income, if an
individual is uninsured for fewer than three months, if
an individual’s income is below the federal tax-filing
threshold, or if the individual meets other criteria for
exemption described in the ACA. New employerresponsibility
provisions will apply to firms with 50 or
more full-time equivalent employees.
Each of these provisions will have an impact on
employer decisions to offer coverage and individuals’
choices in taking up health care coverage. For employers
with employees that...

Our base scenario for enrollment in the Exchange is
based on the probabilities found in the literature due
to changes in cost of coverage for individuals with different
incomes, health status, English proficiency, and
starting point of coverage. In the enhanced scenario,
we assume that language is not a barrier to enrollment,
that eligibility and enrollment processes and systems
are simplified, and that the state launches a robust
outreach and education effort to make individuals
aware of their coverage options. Under these conditions,
we assume that 75 percent of uninsured adults
who are eligible for subsidies enroll. Unless otherwise
stated, estimates are for 2019 after employers and individuals
have fully adjusted to the...

Using the CalSIM model, we predict changes in coverage
in California as a result of the ACA. Take up of
available coverage options in the model is based on a
wide range of factors, including the pre-policy starting
point, health status, household income, change in cost
to purchase coverage, and English proficiency. For
Medi-Cal, we assume that 61 percent of uninsured
newly eligible individuals, and 10 percent of those who
were previously eligible but not enrolled, enroll under
our base scenario. is assumption is based on current
Medi-Cal take up in the state.8 For the enhanced
scenario we follow the Urban Institute/Kaiser Family
Foundation9 enhanced participation estimate and
assume that 75 percent of...

We predict that in 2019, Medi-Cal coverage will
increase by 1.2 to 1.6 million (under the base and
enhanced scenarios, respectively). Enrollment in
Healthy Families will decline slightly as older children
under 133 percent FPL will now qualify for Medi-Cal.
An estimated 1.8 to 2.1 million will be enrolled in the
Exchange with subsidies, while 2.1 to 2.2 million will
remain in the non-group market or be enrolled in the
Exchange without subsidies.11 Finally, the number of
uninsured will decline by 1.8 to 2.7 million people,
leaving 3.0 to 4.0 million Californians without coverage.
Of the remaining uninsured, about 1.0 million will
not be eligible for subsidies or to purchase insurance

Under the base enrollment scenario, the ACA is predicted
to result in an additional 900,000 individuals
enrolling in Medi-Cal by 2014, increasing to 1.2 million
by 2019. is includes an estimated 500,000 individuals
predicted to be enrolled in county Low-Income
Health Programs who will be automatically enrolled
in Medi-Cal in 2014.12 Under the enhanced scenario,
with a more aggressive enrollment and outreach
strategy, additional Medi-Cal enrollment would reach
1.4 million by 2014 and 1.6 million by 2019.
Under the base enrollment scenario, we project that in
2014, 900,000 individuals will take advantage of premium
subsidies in the Exchange to buy coverage. With
more aggressive outreach and enrollment assistance

An estimated 3 to 4 million Californians are predicted
to remain uninsured in 2019. Of those, slightly more
than 1 million will not be eligible for coverage options
under the ACA due to immigration status. Another
800,000 to 1.2 million will be eligible for Medi-Cal or
Healthy Families. If and when they seek care, they will
have the ability to enroll in coverage. Robust outreach
and education can also decrease the number of uninsured
who are not aware of coverage opportunities and
are therefore less likely to seek care or receive preventive
services.
Under the base enrollment scenario an additional
800,000 would be eligible for subsidies in the Exchange.
Of these, nearly 100,000...

e California Simulation of Insurance Markets
(CalSIM) model is designed to estimate the impact of
various elements of the ACA on employer decisions to
offer insurance coverage and individual decisions to
obtain coverage in California. e CalSIM model uses
four data sources: the 2004–2008 Medical Expenditure
Panel Survey (MEPS) Household Component (MEPSHC)
and the Person Round Plan (MEPS-PRPL) public
use data files, the 2009 California Health Interview
Survey (CHIS), California Employment Development
Department (EDD) 2007 wage distribution, insurance
offer, and firm size data, and the 2010 California Employer
Health Benefits Survey (CEHBS). CHIS, EDD,
and CEHBS provide weights and wage distributions
that adjust the nationally-representative MEPS data to
build a California-specific model....

Once re-weighted,
the MEPS-HC respondents are then assumed to represent
the population of California. However, MEPS-HC
does not include data on immigration status, and until
2007 did not report whether an individual was born in
the United States. We therefore constructed a regression
model using CHIS 2009 confidential data to predict
the immigration status of MEPS-HC respondents
based on a variety of socioeconomic, demographic,
and family characteristics. By accounting for immigration
status within the individual dataset construction
process, the CalSIM model is able to adjust Medi-Cal
and Exchange eligible populations based on undocumented
immigrant and recent legal permanent residence
status before determining firm and individual
coverage decisions, rather than imposing an ex post
adjustment. is approach...

Individuals are then identified as workers and nonworkers
(i.e., the unemployed and the respective dependents/
spouses of workers). Workers are assigned
employer wage distribution characteristics from EDD
2007 data based on firm size and insurance offer status
from their MEPS record. e firms are then statistically
matched to the Employer Sponsored Insurance (ESI)
data from the 2010 CEHBS, which contains additional
information on the actuarial value of the health plans
offered. e matched dataset is used to create synthetic
firms consisting of workers and their families,
who then choose to participate in different aspects of
the ACA, such as taking up coverage or dropping coverage.

How well older people make economic decisions is an important issue for social policy.
Since wealth tends to accumulate over one’s lifetime, a large portion is in the hands of older
people. Both long-term trends (increased longevity) and short-term trends (baby booms)
mean that increasing proportions of the population are older and retired. Also, older people
are more likely to vote than young people are, so they may have disproportionate political
influence. It is conceivable that our scientific model of economic decision making, so heavily
rooted in studies of 20-year-old students, is a misleading guide to the behavior of older
people....

We studied four types of decisions with a potential for age effects. One feature of wisdom,
which presumably is acquired over a lifetime, is meta-knowledge, accurately knowing one’s
own knowledge and abilities.We assessed this through self-reported confidence on answers
to trivia questions. A common stereotype of older people is that they are “conservative,
dislike taking risk, and are set in their ways”. We tested this stereotype using choices over
monetary gambles similar to those performed by psychologists and biologists; the monetary
gambles include incomplete and complete information designs (i.e., where probabilities are
known ex ante or unknown)....

A third group of experiments explored possible differences
in willingness to pay and willingness to accept. In these experiments, the choices involved
valuations of everyday objects (e.g. a coffee mug). It has been suggested that observed
differences are due to an asymmetry of preferences between losses and gains that might be
exacerbated by age. Finally, both younger and older subjects participated in beauty contest
games, in which strategic thinking plays a central role. In each case, the experiments were
taken from the literature allowing us to focus on age differences rather than on theories
behind the experiments....

As
other populations of older adults (e.g. individuals with Parkinson disease or other ailments or
people in assisted living arrangements) may be more difficult to study,we chose a population
of healthy high-functioning individuals for our first attempt to study decision making in the
elderly.
Each subject completed an individually administered interview, involving a written questionnaire
and several interactive tasks. On average, subjects of both populations took 50 min
to complete the interview. For all areas of the investigation involving monetary rewards,
real cash was used. This method of collecting data is expensive, but for many populations
of older adults living outside of retirement communities, individual interviews may be a
necessary...

Fat tissue may increase toward the centre of the body, including around the abdominal organs. The loss of muscle mass in the legs and changes in body shape can affect her balance, leading to falls. A woman may appear shorter as she ages. This height loss is related to aging changes in the bones, muscles, and joints. Women typically lose about 1 cm (0.4 inches) every 10 years after age 40. Height loss is even greater after 70 years old. In total, she may lose 1 to 3 inches in height in rest of her life. Women usually gain weight...

Age-related hearing loss or presbycusis is mainly caused by changes in the inner ear. However, your genes and loud noises (such as from rock concerts or music headphones) may play a large role. Initially there is difficulty in hearing high-frequency sounds, such as someone talking. As hearing gets worse, it may become difficult to hear sounds at lower pitches. Hearing aids Telephone amplifiers and other assistive devices may be helpful. A cochlear implant (Surgery) may be recommended for certain women with very severe hearing loss. The implant makes sounds seem louder, but does not restore normal hearing....

The bones lose calcium and other minerals especially in women after menopause. The trunk becomes shorter as the gel-like cushions or intervertebral disks, between each spine bone (vertebrae) gradually lose fluid and become thinner along with gradual loss of mineral content of vertebrae itself, making each vertebra thinner. As a result, the spinal column becomes curved and compressed (packed together). The foot arches become less pronounced, contributing to a slight loss of height. The arms and legs look longer when compared with the shortened trunk. Bones become more brittle and may break more easily. The joints become stiffer and less...

After 40 the muscle fibbers shrink and replaced slowly with a tough fibrous tissue.Muscle changes often begin in the 40s in women. Lipofuscin (an age-related pigment) and fat are deposited in muscle tissue. This is most noticeable in the hands, which may appear thin and bony. Muscles may become rigid with age and may lose tone, even with regular exercise. Loss of muscle mass reduces strength which contributes to fatigue, weakness, and reduced activity tolerance. Exercise is one of the best ways to slow or prevent problems with the muscles, joints, and bones....

Evidence of increasing age includes wrinkles and sagging skin. Aging skin appears thinner, more pale, and clear (translucent). Thus, skin is at higher risk for injury. Large pigmented spots (called age spots, liver spots, or lentigos) may appear in sun-exposed areas. The blood vessels of the skin become more fragile. This leads to bruising, bleeding under the skin. Women’s skin gradually produces less oil beginning after menopause. This can make it harder to keep the skin moist, resulting in dryness and itchiness. The sweat glands produce less sweat. This makes it harder to keep cool, and they are at increased...

Due to decreasing muscle tone the jowls may begin to sag, leading to a double chin. Nose may lengthens slightly and may look more prominent. The ears may lengthen slightly in some women. The eyebrows and eyelashes become gray. The skin around the eyelids becomes loose and wrinkled, often making a crow's feet pattern. The eye socket loses some of its fat pads, making the eyes look sunken and limiting eye movement. The lower eyelids may appear baggy, and drooping eyelids are fairly common. The outer surface of the eye (cornea) may develop a grayish-white ring called arcus corneus or...

Breasts lose tissue and subcutaneous fat, reducing breast size and fullness. Most of the mammary glands are replaced by fat tissue so make the breast less firm. Nipple may turn in slightly. The area surrounding the nipple (the areola) becomes smaller and may nearly disappear. Lumps are common around the time of menopause. Breast cancer risk increases with age. Women should perform monthly breast self-examinations and should also talk to their health care provider about mammograms (Breast scans).
Changes in the Vision
Aging eyes produce fewer tears. The cornea becomes less sensitive, so injuries may not be noticed. By the time someone...

As life expectancy continues to rise, one of the
greatest challenges of public health is to improve
the quality of later years of life. The aim of this
present study was to analyze the quality of life
profile of the elderly across different demographic
and socioeconomic factors. A cross-sectional
study was carried out in two stages, involving
1,958 individuals aged 60 years or more. Health
related quality of life (HRQOL) was assessed using
the SF-36 questionnaire. The lowest scores
were found among measures for vitality, mental
health and general health and the highest among
factors including social functioning and role limitations
due to emotional and physical factors.
HRQOL was found to be worse among...

Sharpness of vision (visual acuity) gradually declines and eventually bifocals are need. One may be less able to tolerate glare, and may have more trouble adapting to darkness or bright light.
The fluid inside eye may change. Small particles can create floaters in the vision not a dangerous condition. However if someone suddenly develop floaters or have a rapid increase in the number of them, she should have checked her eyes by a professional.
Common eye disorders in the elderly include cataracts (progressive opacification and hardening of the lens of the eye, glaucoma (increased pressure in the eye, if left untreated may...

The ovaries stop releasing eggs (ova), and menstrual periods stop (Menopause). Most women experience menopause around age of 45 to 50. Prior to menopause, menstrual cycles often become irregular.
The vaginal walls become less elastic, thinner, and less rigid. The vagina becomes shorter. Secretions become scant and watery. The external genital tissue decreases and thins (atrophy of the labia). A woman may experience changes in her sex drive (libido) and her sexual response may change, but aging does not prevent a woman from being able to have or enjoy sexual relationships. The pubic muscles lose tone, and the vagina, uterus, or...

Theoretical development in the area of health change in an older population began
with the realization that the rapid mortality decline among the old beginning in the
late 1960s could be linked to important population health consequences (15, 75).
Fries (36) generated some of the interest in trends in health with his promotion
of the idea that there was an ongoing “compression of morbidity.” His assertion
rested on assumptions that mortality at the older ages would reach a limit beyond
which there could be no further decline and that there was an ongoing increase in
the age of disability onset. Under these conditions, there would be a...

This discussion first reviews early theoretical clarifications of how population
health change is linked to reduction in mortality at older ages. We briefly
discuss evidence of trends prior to recent decades, subsequent understanding of
trends from empirical models of health, and developments in understanding the
dimensions of health and the process of health change for an aging population.
Recent trends in each dimension of health are then reviewed, ending with a discussion
of trends in healthy life, which is a combination of mortality and morbidity
dimensions....

Interest in trends in the health of the elderly has become widespread in recent years.
Until about two decades ago, trends in mortality were assumed to provide a good
indicator of the health of the elderly, and because mortality was decreasing fairly
steadily, it was assumed that health was improving. Subsequently, both researchers
and policy makers have come to understand that health is a multidimensional
concept and that trends in mortality do not necessarily represent trends in all other
dimensions of health; and, in fact, change in all dimensions does not have to be
similar....

This optimistic view of Fries was replacing a pessimistic view, termed the
failure of success, expressed earlier by Gruenberg (38). This view, also based on
limited evidence, felt that the extension of life for persons with chronic conditions,
without a reduction in the incidence of these conditions,would lead to deterioration
in population health. Manton (48) proposed a position somewhere between the
two outlined above. His view, termed dynamic equilibrium, hypothesized that the
severity and rate of progression of chronic disease would be related to mortality
changes so that, with mortality reduction, there would also be a reduction in the
rate of the deterioration of the vital organ systems...

The above theoretical discussions have been useful in clarifying that one needs
to use a basic epidemiological approach in thinking about the relationship between
trends in different aspects of health. Mortality is a dynamic process that removes
people from the population at a faster or slower rate over time. The number or proportion
of people who are not healthy in a population is an indicator of population
health—or a stock measure—at a point in time. This indicator is affected by a number
of dynamic processes: the age-specific onset rates of unhealthy conditions, the
rate of health deterioration of people with these conditions, and the likelihood that
Annu. Rev....

The theoretical approaches described above were developed without reference to
empirical findings. Initial examinations of empirical health trends indicated that
the trends differed when different aspects of health were examined and that some
indicators showed improving health and some deteriorating health. For instance,
Verbrugge (76) noted that from 1972 to 1981 there were increases in reported
disease presence and disability, yet improvements in self-reported health.Anumber
of researchers from a variety of countries noted that the 1970s were a period of
decreasing mortality and increasing disability....

To begin, at the left of the figure, trends in risk factors or biological markers
such as cholesterol and other lipids, weight, and indicators of insulin regulation are
separate markers of underlying health and population propensity to disease. At the
population level, the age of onset of these factors generally precedes the onset of
related diseases like cardiovascular disease and diabetes. The second box includes
diseases, conditions, and impairments. Sometimes it is difficult to separate diseases
from conditions that may or may not have a clear disease process and may or may
not have associated impairment. Cognitive deterioration is not always linked to a
recognized disease process, and...
