Introduction
Results
  • A total of 32 patients receiving inpatient and
    outpatient mental health services were enrolled
    in the study. Participants were recruited from
    two sites in Lincoln, NE the Community
    Transition Program (CTP) at the Lincoln Regional
    Center (n 18), and the Community Mental Health
    Center in Lincoln (n 14). Inclusion criteria
    for the treatment group (n 16) were current use
    of clozapine (Clozaril) and/or olanzapine
    (Zyprexa).
  • The mean age for all participants is 41 years
    (SD 11.48 range 22 to 56 years). Most
    participants were European-American (87.5) and
    12.5 African-American. More males (75) than
    females (25) participated in the study. Of the
    patients in the treatment group, 68.8 were
    currently taking clozapine and 31.3 were taking
    olanzapine.
  • Participants in the treatment group reported
    eating an average of 3 full meals per day, and an
    average of 1.8 snacks per day. The majority
    (56.3) of patients taking clozapine and/or
    olanzapine reported to have gained weight over
    the past six months. Most patients believed that
    a persons weight is related to their eating
    habits (85). A moderate effect was found for
    patients beliefs about needing medication (73)
    and their attribution of weight gain to their
    medication (73). Perceived effectiveness of
    medication for experienced symptoms was somewhat
    smaller (67).
  • A mixed groups factorial ANOVA was performed to
    examine the effects of Time and Study Group
    regarding weight gain among the control group and
    the medication group (those people taking
    clozapine and olanzapine). Table 1 shows the
    means for each condition of the design. The
    interaction of Time and Study Group as they
    relate to weight gain approached significance
    (F(3, 54) 2.683, p .056, Mse 160.94). As
    hypothesized, the pattern of this interaction was
    that weight increases over time more for the
    Medication Group than the Control Group. Despite
    having an interaction which approached
    significance, the main effect of Time (F(3, 54)
    .219, p .883) was not significant. In addition,
    the main effect for Study Group (F(1, 18) .242,
    p .628) was also not significant.
  • With respect to those people taking clozapine
    and those taking olanzapine, there were no
    significant differences between location, gender,
    ethnicity, history of obesity, history of
    diabetes, familial history of obesity, or
    familial history of diabetes. Regarding
    performance on the structured interview, no
    significant differences were observed between the
    mean scores of those people taking clozapine and
    those taking olanzapine (Table 2). Despite the
    lack of statistical significance, those people
    taking clozapine had higher mean scores on the
    four domains of the interview than those taking
    olanzapine with the exception of Beliefs About
    Weight Gain. Table 2 provides the weighted means
    scores for each group for each domain and the
    standard deviation of each group.
  • The graph below shows change in weight over
    time for each of the 16 participants in the study
    (each colored line represents one participant).
    There are marked co-fluctuations in weights which
    may reflect the changes in weight over time in
    which some data was incomplete, thus the changes
    look more disparate. The solid line represents
    the trend line for the medication group and the
    dashed line represents the trend line for the
    control group.
  • Following the market entrance of clozapine and
    olanzapine there has been an increasing amount of
    discourse among mental health providers about the
    observed weight-gain associated with the use of
    both medications (Gothelf et al., 2002 Kinon,
    Basson, Gilmore, Tollefson, 2001 Lewis, 2002
    Malyuk, Gibson, Procyshyn, Kang, 2002).
  • Examining the attitudes and beliefs about
    weight gain among people with serious mental
    illness provides information about the
    effectiveness and potential drawbacks to using
    clozapine and olanzapine as a method of treatment
    for psychotic symptoms.
  • In addition, knowing how people with serious
    mental illness think and feel about their
    medication has implications for their level of
    treatment compliance, relative degree of
    depression, and vulnerability for developing
    new-onset diabetes mellitus and obesity
    (Umbricht, Flury, Bridler, 2001 Vanina et al.,
    2002 Webster, Devarajan, Gallant, Harris,
    Kopala, 2001).
  • It is hypothesized that weight gain experienced
    by those persons taking clozapine or olanzapine
    will be viewed negatively, those who experience
    weight gain while taking clozapine and olanzapine
    will attribute their weight gain to the
    medications, and weight gain will contribute to
    negative beliefs about the clinical effectiveness
    of clozapine or olanzapine.

Discussion

Method
  • The results of this study should be interpreted
    with caution due to the small sample size (N
    32). Thus the findings presented represent a
    first look at the relationship between weight
    gain due to clozapine and olanzapine and four
    domains which may change in relation to the
    subjective experience of weight gain due to
    antipsychotic medications. One barrier
    encountered in course of this study was the
    completeness of weight data included in patients
    medical charts. For participants in the
    medication group it was difficult to determine
    weights prior to the date on which they were
    first prescribed clozapine and olanzapine,
    because of this weight data was aggregated into
    four 6-month variables for the purpose of
    analysis.
  • As indicated in the weight chart, there were
    differences in weight among those in the
    medication group and those in the control group.
    Although these results did not reach
    significance, the predicted direction of change
    is supported by the authors hypotheses and
    preliminary evidence suggested by Vanina, et al.,
    2002.
  • With respect to responses to the structured
    interview, the results failed to provide a clear
    explanation for how those people taking clozapine
    and olanzapine regarded their medications.
    Although group differences approached
    significance, the results were not powerful
    enough to make this distinction clear. For this,
    a larger sample size is needed to find the
    effect. The finding that those people taking
    clozapine had higher scores on the interview
    might be a reflection of level of care, as most
    people prescribed clozapine were outpatients.
    These results may also suggest that those people
    taking clozapine regard their medications more
    highly, although this finding would need
    additional research as previous studies of
    patient satisfaction with clozapine (e.g.,
    Czobor, et al., 2002) have revealed some dislike
    due to the reported side effects.
  • While more research is needed, these results
    have important implications for the course of
    treatment for those people with SMI. It has been
    suggested that those people who experience an
    increase in weight as a result of their
    medication have the potential to develop
    depression, diabetes, low self-esteem, obesity,
    an increase in suicidal ideation, and may become
    less compliant with treatment (Sheitman, et al.,
    1999 Vanina, et al., 2002).
  • As treatment research and mental healthcare
    providers strive to find ways of increasing and
    improving treatment compliance, the topic of
    beliefs and attitudes about medication become
    ever more important. Additionally, as the
    pharmaceutical industry continues in its efforts
    to modify and create new medications it is
    important for them to know how the side effects
    of such medications impact their clients.
  • Two groups of individuals were used in this
    research each group was comprised of inpatients
    of the Lincoln Regional Center (LRC) and people
    receiving outpatient treatment at the Community
    Mental Health Center (CMHC) of Lancaster County
    in Nebraska.
  • The participants in the antipsychotic
    medication group (N 16) were receiving either
    clozapine (Clozaril) or olanzapine (Zyprexa) and
    those participants in the control group were not
    receiving clozapine or olanzapine for the
    treatment of their symptoms.
  • The control group (N 16) was constructed
    using a matched-control design on the basis of
    date of birth within one year, gender, ethnicity,
    date of admission within two months, and weight
    within 10 pounds at the time the matching
    participant began pharmacological treatment.
  • For those in the antipsychotic medication
    group, retrospective weights were collected from
    the medical charts for one year prior to
    antipsychotic medication treatment and
    retrospectively, for an additional year following
    initiation of antipsychotic treatment.
  • For those in the control group retrospective
    weights were collected from the medical chart for
    two years, with a midpoint that matched the
    initiation of antipsychotic treatment in the
    antipsychotic medication group.
  • Those participants who are currently admitted
    were given a structured interview to access their
    attitudes and beliefs about the need for
    medication, eating habits, weight gain,
    attributions of weight gain to antipsychotic
    medication, clinical effectiveness of
    antipsychotic medication, family history of
    diabetes mellitus, and family history of obesity.
